INTRODUCTION
The Simrad PI54 is an integration of proven commercial fishing
technologies which can dramatically increase the yield and
effectiveness of purse/danish seining and bot tom/pelagic
trawling applications.
By means of six underwater sensors mounted on the gear, this
robust, maintenance-free catch monitoring system allows
unparalleled control over fishing operations by providing
continuous, centralised information on the vessel’s position, its
gear and the environment at and below the surface.
This manual is not intended to be read from cover to cover, but
is designed as a book of references that you can consult
whenever necessary.
This manual describes PI54 software version 0.40.

SYSTEM DESCRIPTION
The Simrad PI54 catch monitoring system consists of an
operator station, a hydrophone and an optional echo sounder
transducer. The hydrophone and the transducer are both
mounted under the vessel’s hull. The system further comprises a
number of small and robust sensors measuring the conditions on
your fishing gear.
The PI54 catch monitoring system can work with six sensors
simultanously.
The sensors are powered by built-in rechargeable bat teries. They
are housed in titanium casings, and designed using advanced
shock absorbing materials. The information collected by the
sensors are sent through the water to the hydrophone by means
of coded sound waves. From the hydrophone, the signals are
sent to the operator unit, which decodes the information,
interprets it, and finally present it to you.

Operator Unit
The PI54 Operator Unit is a marine grade electronic
instrument incorporating an impact resistant polycarbonate front
panel, die-cast aluminium housing and watertight electrical
connections.
The PI54 electronics are sealed in the operator unit allowing the
it to be flush or bracket mounted in the wheelhouse or at an
exposed control station.
Computed information is displayed in both numerical and
graphical form on the display. The unit is operated using
drop-down menus and an integrated keypad.

850-165186 / Rev.B
Hull mounted and portable hydrophones
Two hull mounted hydrophones are available, one for purse
seining operations, and one for trawl operations. You can install
both, and then select active hydrophone by means of a selector
box on the bulkhead.
Purse seining: The hull mounted
hydrophone for purse seining operations
has a 90 degrees horizontal beam and a
30 degrees vertical beam to provide the
PI54 with optimal reception from the
sensors. T his specific beam pattern is
especially suited for purse seining and the
wide coverage area reduces the need for
careful alignment.
Trawling: The hull mounted hydrophone f or trawling
operations has a 50 degrees horizontal beam and a 30degrees
vertical beam to provide the PI54 with optimal reception from
the sensors. This specific beam pattern is especially suited for
trawling and the wide coverage area reduces the need for careful
alignment.
Portable: A portable hydrophone is also
available. It is designed as a temporary
measure until a fixed hydrophone can be
installed at the vessel’s next planned dry
docking. It has an omni-directional beam
and a 50 meter integrated cable which is
sheathed in polyurethane providing robust
external protection to compliment its 150
kg tensile strength. The cable is supplied on
a reel for convenient retrieval and stowage,
and is equipped with a plug for easy
attachment to the Operator Unit.

Sensor overview
This chapter provides a very short description of each sensor.
• Depth sensor - The Depth sensor provide infor mation about
the current depth as well as the descending or ascending rate
related to the surface.
• Catch sensor - The Catch sensor provides information about
the amount of catch in the trawl. The sensor monitors the
opening of the meshes in the cod-end, and will activate once
the caught volume pulls the detector wire. To monitor the
filling rate, you are adviced to use minimum two sensors.
• Bottom Contact sensor - The Bottom Contact sensors
detects if a trawl is accidentally lifted off the seabed, or a
purse seine is touching the bottom.
• Rip sensor - T he Rip sensor provides an immediate warning
when the net is ripped.
• Temperature sensor - Temperature sensors read and transmit
the ambient water temperature at the gear depth.
• Height sensor - The Height sensor contains s small echo
sounder to measure the current depth related to the seabed.
• Spread & Remote sensor - These sensor always work in
pairs, and they measure the distance betwen the trawl doors.
You can also use two Remote sensors if you run a twin trawl.
The use of separate communication channels f or the individual
sensors allows you to use your sensors in the vincinity of other
vessels using PI or PS sensors. The communication channels can
be defined and/or changed onboard your vessel using a standard
computer and the PI Configurator utility.

Battery chargers
All sensors are power by internal batteries, and these need
charging at regular intervals. The Simrad chargers have been
designed to allow the sensors to be stored in charging positions
whenever they are not used, and “overcharging” will not take
place. Either of the two charger types can be used on any of the
sensors, but the PI Charger will only provide fast charging on
the PI Sensors.
PS30 Charger
Three different Simrad PS30 Chargers are
available depending on the vessel’s main power
supply; 230 Vac, 110 Vac and +24 Vdc.
PI Charger
The PI Charger will provide fast charging of the
new PI sensor series. The Simrad PI Charger
requires a +12 to +32 Vdc power supply.

Introducing the sensors
The PI54 catch monitoring can be used with a variety of
sensors. All these sensors can be placed on your trawl or purse
seine to monitor key parameters.
On the PI54, you can use maximum six sensors simultanously.
There are two sensor families; PI and PS. The sensors in the
two families are almost identical, and they can be used together
on the same PI54 system. The PI sensors will however offer
increased range, some added functionality, and they can also be
charged much faster using the PI Charger.
Bottom Contact: Best at the bottom!
With patented technology and awardwinning design, Simrad
provides you full control of the actions that take place at the
bottom. Mounted on a bottom trawl, pelagic trawl or purse
seine, this sensor will provide the important information when
you need it!
(A) = The Bottom Contact sensor mounted on a bottom trawl
will let you know once the trawl lifts a few centimeters above the
bottom. You can then immediatley perform the necessary
adjustments, and you will not loose any catch.
(B) = On a purse seine you will be notified once the seine
reaches the bottom, and you can thus fish even on a rough
bottom.
(C) = On a pelagic trawl, the sensor will notify you once you get
near the bottom.
The Bottom Contact sensor will let you know immediately if
your gear touches the bottom.
• Bottow trawl: If your trawl lifts off the bottom, this may
cause fish to escape, and hence reduce the catch. This sensor
will detect this, and allow you to trim your equipment for
perfect balance.
Getting started
21
850-165186 / Rev.B
• Pelagic trawl: On a pelagic trawl, this sensor proves very
useful when the trawl moves downwards. It will let you
know immediately if the footrope touches bottom.
• Purse seine: When you work with a purse seine, you need to
know when the seine reaches the bottom. This sensor will let
you know. once it happens.
• Danish seine: Used on a Danish seine, the sensor will let you
know when the net has a stable bottom contact, and when it
is time to haul.
• Scientific research: During scientific surveys, an exact
definition of towed distance with proper ground gear contact
is an essential parameter in bottom trawl swept area estimates
of fish abundance. Using a Bottom Contact sensor will
reduce errors in this key parameter.
Catch sensor: When is the trawl full?
This is your “eye” at the cod-end. With PI Catch sensors in use,
you can easily monitor the fi lling rate and the amount of catch
in the trawl. Save time and fuel, haul in the trawl at the right
moment! The design is rugged and awardwinning, and the
sensor’s sensitivity is easily adjustable for trawls of all sizes.
Some professionals claim that the Catch sensor is the most
important sensor on the trawl. Why? Because it will tell you the
amount of catch in the trawl.
The sensor simply monitors the expansion of the meshes in the
cod-end. Once the volume caught is enough to expand the
meshes, they will pull the detector wires and engage the sensor.
The sensitivity of the sensor can easily be adjusted, just extend
the detection rubber b ands to span additional meshes.
To monitor the filling rate, we recommend that you use
minimum two sensors. Place the first sensor at the far end of the
cod-end, it will tell you that the trawl is actually fishing. Place
the second sensor closer to the trawl opening. Once the trawl is
filled to the chosen location, the sensor is engaged, and you
know that it is time to haul.
Use the PI Catch sensor to adjust the catch volume according to
the production capacity, check that the trawl is fishing, adjust
the caught volume to secure quality, and minimize the towing
time to save fuel. These are only a few of t he reasons why this
sensor is considered to be so important.

850-165186 / Rev.B
Depth: How deep can you go?
When the sonar and echo sounder tell you how deep the school
goes, it is good to know that you can place your fishing gear at
the same depth. And even better, you can monitor and hold the
desired depth. The design is rugged and awardwinning, and the
sensor is available for three different depth ranges.
The PI Depth sensor provides information about the current
depth and the depth changes of your gear.
• Bottom trawl: On a bottom trawl, you will use the sensor to
achieve full control when shooting, and t o position the trawl
on the slope.
• Pelagic trawl: During pelagic trawling, you know how
important it is to position the trawl relative to the largest
concentration of fish. By using a Depth sensor, you can
monitor the exact depth relative to the surface, and adjust the
trawl depth accordingly. Additional depth sensors on the
doors will monitor if the doors stay at the same depth.
• Purse seine: During seining, use the Depth sensor to monitor
the depth of the net, and the descending speed of the net.
Then you will know when to start pursing, and which speed
to use.
• Danish seine: Mounted on a Danish Seine the Depth sensor
monitors the sinking speed of the net, and it will tell you
when to start hauling once the net has stopped sinking.
Height sensor: Accurate distance to the bottom!
With a built-in echo sounder, this new PI sensor is full of
advanced technology. Wherever you place it, it will always tell
you the exact distance to the bottom.
The height sensor measures the height over the bottom, that is
the distance from the bottom and up to wherever the sensor is
located. This provides you with a valuable range of applications
for bottom and pelagic trawling.
• Bottom trawl: Place the sensor behind the headrope, and it
will tell you the height of the trawl opening. This allows you
to adjust you equipment immediately if the opening is
reduced, and you will avoid loosing catch.
• Pelagic trawl: With a height sensor behind the footrope you
will know at once if the trawl approaches the bottom. If you
use a second sensor behind the headrope, the difference
between the two measurements will give you the height of
the trawl opening.
Getting started
23
850-165186 / Rev.B
Rip: Check for damages!
The Rip sensor is identical to the Catch sensor, and can thus be
regarded as a application for the Catch sensor. Place the sensor
on the trawl belly behind the footrope, and use it to detect if the
trawl is torn o r in any other ways damaged by r ocks or other
roughness on the bottom. If this is detected immediately you can
adjust the gear to minimise the damage.
Spread and Remote: Check the trawl doors!
This dynamic duo tells you the exact distance between the trawl
doors. Used on bottom and pelagic trawls the Spread and
Remote sensors p rovide crucial information about your trawl
behaviour. On a twin trawl, simply add a Remote sensor and
you have both openings covered!
These two sensors always work in pairs. They are used to
monitor the physical distance between the trawl doors during
bottom and pelagic trawling.
Use a Spread sensor on the port door and a Remote sensor on
the starboard door. Both sensors are normally mounted in
special adapters, but you may also attached them to the
wing-end or warp using snap hooks or rope.
The Spread sensor communicates with the Remote sens or using
a special transverse communication link. By means of this link it
measures the excact distance (maximum 350 meters) between
the two sensors. The information is is transmitted t o the vessel
by the Spread sensor.
As you already know, correct door spread is important in order
to obtain the correct sweep-angle, as this ensures optimal trawl
performance. Door behavior and stability during shooting and
towing is also monitored by these sensors. Many regard this pair
of sensors one of the most important sensors to obtain efficient
trawling.
A special version of the PI Spread sensor, The PI Twin Spread,
allows you to use a single Spread sensor with two Remote
sensors to monitor a twin trawl.
Temperature: Too warm or too cold water?
Fishingintoowarmortoocoldwatermaybejustawasteof
time and money. The same applies to a pelagic trawl placed on
the wrong side of a thermal layer. Using advanced technology,
rugged construction and awardwinning design, the PI
Temperature sensor allows you to increase your fishing
efficiency.
The PI Temperature sensor tells you the exact sea water
temperature while you are fishing.
Simrad PI54
24
850-165186 / Rev.B
The water temperature is an important parameter. Fish and bait
are temperature sensitive, and they are normally found within
specific temperature zones for feeding and spawning.
However, the temperature layers in the water are changing
constantly, and for this reason the temperature must be
monitored constantly. Fishing in an area with unfavourable
water temperature might be just a waste of time!
For any kind of trawling, use this sensor to monitor ing and log
the temperature. Then, increase your knowledge about the
correlation between temperature, fish concentration and catch
efficiency. On a purse seine net, monitor the temperature to see
when you are passing the thermo-cline.

The Status display shows sensor data, signal thresholds and
background noise levels providing an overview of present
hydro-acoustical conditions and the margin for reliable signal
detection. Other information displayed includes cable status,
program version, and echo sounder / position information.
Note that some of the information provided by the Status
display assumes that you have the relevant sensors connected to
and operational on your PI54 system.
The Status display can only be set up as a full screen feature.

The numeric displays at the top of the Status display provide
the current information from the active sensors. Due to the lack
of space, the information from the sensors have been
abbreviated slightly. For a more detailed presentation, you must
select the the Numeric display presentation.

SW: This sentence provides the current software version in your
PI54 system. Main is the operational software providing the
user interface, µC is the P I54 microcontroller, while DSP is the
software controlling the digital signal processor, that is the
reception and interpretation of sensor information.

the code will be 0 (zero).
Hydrophone: A yellow indicator is provided when the
hydrophone is connected and fully operational. If the indicator
is red, a short circuit has occurred. If the indicator is black, the
PI54 has lost electrical contact with the hydrophone.
NMEA1/2: Any information accepted by the NMEA interface

(C) Frequency spectrum
This graph provides you with information about the background
noise and the signal strength of the frequency band or channel
number selected. Each vertical bar represents the background
noise for the given frequency or channel, and the level is
measured continuously.
To select spectrum display, press the ADJ button to open the
Status setup dialogue, and select Spectrum, display to show
Frequency or Channel. In most cases a Channel view will be
most useful to you.
This function is very useful if you have too much noise and this
makes the communication with the sensor unreliable. Switch off
as much electrical, mechanical and acoustic gear and equipment
as possible. Then, switch the systems on again one by one while
keeping an eye on the frequency spectrum. When the “noisy”
system is activated, it is most likely easy to see!
Note that the frequency spectrum presentation depends on the
Interference filter setting.
(D) Gain indicators
There are six gain indicators, one for each of the current
sensors. At the top of each indicator you can see sensor number
and sensor type, at the bottom you can see the sensor’s
communication channel and current update rate.Green colour
indicates that the reception of signals and noise is within normal
specifications. Red colour indicates that the received signal
exceeds the minimum level required for reception, this is
therefore not an error message.
For the technical minded: When no sensors have been deployed,
the indicators will present the mean noise level. This is the noise
in the surrounding water, caused by mechanical, electrical,
acoustic and natural disturbances. This noise level should be as
low as possible. When a sensor in the water transmits its
information back to the PI54, this is indicated as the green
indicator extends above the mean noise level. In order for the
reception circuitry to accept and recognize the signal, it must be
stronger than a predefined minimum level. The level is normally
referred to as the detection level. If the signal is stronger than
the detection level, the indicator bar will change colour to red.

How to set up the sensors
The very first time you switch on the PI54, you will need to set
up the sensor conf iguration. This will also be required if you
perform a “master reset” on the PI54, and then reload the
manufacturer’s default settings.
Observe the following procedure to establish the most common
values. For more detailed information about the settings, refer to
the References chapter.
Note: In order to establish the sensor configuration, you need to know
what kind of sensors you have, which channels they
communicate on, and how often they communicate. This
information is required before you start the configuration on the
PI54.
Note: Do not attempt to set up the sensors unless this is absolutely
necessary.
We strongly suggest that you use the forms in the front of this
manual to write down t he sensor you have with information
about their update rates and communication channels.
1 Press the MENU button to open the main menu.
2 Open the Setup menu (4), and select Sensor setup (5).
3 Press the ENT key to bypass the warning page.
4 For each of the sensors you shall use, select the following
parameters:
a Set Sensor type to SINGLE to activate the sensor.
b Set Update rate FAST, SLOW or NORMAL
c Set Measure to chosen sensor type.
d Set Channel to correct communication channel for the
chosen sensor.
5 For operational use, make sure that Demo mode is set to
OFF.
6 When you have defined the sensors, press the ENT
buttom to save the changes and exit.
If you configure less then six sensors, you will be able to set the
Sensor parameter to Dual. You can not use this setting. Dual
sensors are not yet available, and this functionality is not yet
supported by the digital signal processing in the PI54. The
ability to choose Dual is implemented for future expansion only,
and any attempt to choose this setting will not work.
Operational procedures
59
850-165186 / Rev.B
Predefined settings
Each sensor is delivered with a predefined setup. This setup
includes:
• transmission channel for the acoustic communication link
between the sensor and the vessel’s hydrophone
• update rate; how often the sensor sends its readings back to
the PI54 system.
To change the sensor setup, you can call your local Simrad
dealer, or you can do it yourself if you have the proper
equipment, training and the PI Configurator software.
Changing a transmission channel
It may be required to change one or more transmission channels,
and there may be many reasons for this.
• You have more than one of each sensor. For example, if you
have three temperature sensors, they MUST communicate on
three different channels.
• Other vessels near your use the same PI54 system (or a
similar), and they have one or more of their sensors set up to
the same communication channels as you have. This will
create interference, as you will “read” each others sensors.
• If your sensors are set up to use communication channels too
close to each other (for example, you have chosen channels
4, 5 and 6), this will limit the vessel’s speed. The reason for
this is the doppler effect. If the speed is too high, the doppler
will cause the transmission frequencies to change so much
that they overlap, and this will create interference. The PI54
will provide a warning if this is about to happen! You must
then either change to other c ommunication channels further
apart, or reduce the maximum shooting speed.
• If you operate at the maximum range of the sensors, you may
be able to increase this range slightly if you use lower
communication channels. This is because the l ower
communication channels user lower transmission
frequencies.
Changing the update rate
It may be required to change the update rate on a sensor, that is
how often it sends information back to the PI54 system. A high
update rate will give frequent information updates, but the
sensor will use more battery power. If you need your batteries to
last as long as possible, you must consider lowering the update
rate.
Simrad PI54
60
850-165186 / Rev.B
• A low update rate will provide you with fewer information
updates, but the battery will last very long.
• A high update rate will give you frequent information
updates, but the battery will run out faster.
All sensors are provided from Simrad with a default update rate
setting. In some cases you may find that this update rate does
not suit your operational needs. This is a decision you have to
make depending on the local fishing conditions.
How to change the sensor setup
To change the sensor setup, you can call your local Simrad
dealer, or you can do it yourself if you have the proper
equipment, training and the PI Configurator software.

How to mount the sensors on the net
Once the sensor has been coded correctly, you must mount it on
the net. The mounting instructions for each sensor is provided in
the Sensors chapter, and the same information can also be found
on the Quick Reference Guide for each sensor.

How to use the sensors
Once the sensors have been coded and installed on the net, they
will automatically be switched on once they are submerged into
water. The PI54 will then automatically retreive information
from them, and provided that you have chosen the correct
display presentation, the information will be provided to you.
Applications
The various applications available to you with the different
sensors are explained in the Getting started and Applications
chapters.
Display presentation
How to set up the display to see the information provided by the

How to replace the sacrificial water switch
All PI and PS sensors are equipped with a water switch, and two
different types are used. If your sensors are equipped with a
brass screw, observe the following procedure for replacement.
1 Turn the sensor upside down, and locate the brass screw.
2 Inspect the screw for wear and tear. If required, replace
the screw.
A standard commercial brass screw is used. Local supply will
normally be available, but the following specifications must be
met:
Brass, Size M5x10, DIN85A, rounded head
Before a new screw is inserted, Aqua Shield (or a similar
underwater lubricant) must be applied. Due to the size of the
tube, we recommend that the grease is applied from a syringe.
1 Apply Aqua Shield to the screw threads.
2 Insert the screw, mount firmly, but not too hard.
3 Use maximum torque 1.5 NM
A pack with ten screws and a tube of Aqua Shield can be
ordered from Simrad as a spare parts kit.
Aqua Shield is manufactured by D.A.Stuart, Warrenville,
Illinois, USA (www.d-a-stuart.com).

How to calibrate the Depth sensor
Only the Depth sensor can be calibrated. The purpose is to
ensure that the depth reported by the sensor is as accurate as
possible.
This procedure is carried out onboard the vessel.
1 Mount a rope to the top fastening lugs on the sensor.
2 Tighten the rope, and measure one meter from the bottom
of the sensor to a spot on the rope. Place a visual marker
on the rope at that location.
3 Lower the sensor over the side of the vessel and into the

minutes. Meanwhile, observe that the numerical
presentation shows grey characters only.
12 On the PI54, observe that the numerical presentation of
the Depth sensor is stable, and shows 1 meter.
13 Retrieve the sensor from the water.
Note: In order to calibrate the sensor, it must be submerged in salt
water.
You may wish to use a different depth reference t han the sea
surface. If this is the case, change the marking on the rope to fit
you preference, for example the depth of the keel or the depth of
an echo sounder transducer.

How to define sensor offsets
Only the Depth and Spread sensors can have their offset values
adjusted. The pur pose is to allow you to compensate for known
deviations.
You may wish to insert a Depth sensor offset to line up the
depth readings from the sensor with those from your echo
sounder. If the echo sounder transducer is located X meters
below the surface, the Depth sensor should have the same offset
value.
Note: If you have performed a Depth sensor calibration, you will see
than an offset value may already be present. This value has been
provided by the calibration routine.

How to set up a Twin Spread sensor for
twin trawl applications
By means of the Twin Spread sensor, you can set up your PI54
to monitor the openings on a twin trawl. Apart from the Twin
Spread sens or, you will also need two Remote sensors.
Sensor configuration
The Twin Spread and Remote sensors are supplied in sets, and
they MUST operate in these sets. The sets are:
• Twin Spread 1 uses two Remote sensors; Remote 1 and
Remote 3.
• Twin Spread 2 uses two Remote sensors; Remote 2 and
Remote 4.
When supplied from the manufacturer, all Twin Spread sensors
are set up as Twin Spread 1. If you wish to use a Twin Spread 2,
your dealer (or yourself) must reconfigure the sensor using the
PI Configurator application.
Communication channels and update rate
Each Twin Spread se nsor will communicate on two channels,
one for each of the two distances the sensor measures. B y
default, these communication channels ar e set to 02 and 07.
• Channel 02 is used to measure the distance to Remote 1.
• Channel 07 is used to measure the distance to Remote 3.
By default, both communication channels are set up with Fast
update rate. In order to increase the lifetime between each
sensor charging, you may consider changing to Normal update
rate.
If you wish to reconfigure the settings, your dealer (or yourself)
must use the PI Configurator application.
Placing the sensors on the trawl
The Twin Spread sensor must be mounted on the port trawl
door, and the three communication transducers on the sensor
must not be obstructed. Ensure that you have a clear line of
sight between the tip of the Twin Spread sensor and the vessel,
and between the Twin Spread se nsor and the two Remote
sensors.
Remote 1 is placed on the centre clump.
Remote 3 is placed on the starboard door.
Simrad PI54
68
850-165186 / Rev.B
This configuration will allow the Twin Spread sensor to measure
the distance from the port door to the centre clump directly. It
will also measure the distance between the two trawl doors. In
order to calculate the distance between the centre clump and the
starboard door, you must perform the required settings on the
PI54.
(P) = Port trawl
(S) = Starboard trawl
(C) = Port trawl door with the Twin Spread 1 sensor mounted.
(D) = Centre clump with Remote 1 mounted.
(E) = Starboard trawl door with Remote 3 mounted.
(F) = Forward
(1) = Distance between port trawl door and centre clump,
measured direcly by the Twin Spread sensor.
(2) = Distance between the centre clump and the starboard
trawl door, must be calculated by the PI54 system.

When you reconfigure a Twin Spread 1 sensor to act as a Twin
Spread 2, you must also choose two additional communication
channels. You can choose any channels available on your
system.
In this description we will use channels 09 and 11 as follows:
• Channel 09 on Twin Spread 2 is used to measure the
distance to Remote 2.
• Channel 11 on Twin Spread 2 is used to measure the
distance to Remote 4.
If you wish to reconfigure the settings, your dealer (or yourself)

How to set up marker lines
When you have chosen the Graphic display presentation, you
can choose to superimpose the information from the echo
sounder, and then add marker lines to see where your sensors
are located in relation to the bottom and fish echoes. Note that
the echo sounder data will only appear if you have mounted an
echo sounder transducer to the PI54.
The following parameters will affect the way the marker lines
are displayed:
• Width - you can select how thick (in pixels) each marker line
shall be.
• Delay - The echo sounder information is provided by the
transducer, and this transducer is located under the vessel.
The sensors are located on the gear, which may be positioned
several hundred meters behind the vessel. To adjust for this
delay, you can enter a value for Marker line delay.Youmust
calculate this value (in minutes) based on the vessel’s speed,
the wire length and the depth of the gear.
Alternatively, you can use the built-in Trawl caluclator to
find the correct delay.
• Colour - The colour of the marker line is automatically set to
the current Numeric display background colour for the same
sensor. To change that colour, you must access the Display
colour setup page from the Setup menu.
• Expanded view: With the setting Sensor marker in
expansion active, the Depth and Height marker lines are
shown in the expanded areas (Bottom lock, Zoom and Shift),
and thus easier to read. This is a useful feature when the
sensor is towed close to the bottom, and it is particulary
important for the Height sensor.
• Marker white zone: When this setting is enabled, white
pixels are added above and under the marker line to make it
easier to distinguish it from the background colours.
• Height marker in main echogram: This setting is special
for Height sensors. If you have a Height sensor on the top of
a bottom trawl and the trawl opening is small, it may be
difficult to tell the Height marker from the bottom echo. If
this is the case, set this function to Off, and view the Height
marker in expanded mode only.
Simrad PI54
82
850-165186 / Rev.B
• Height reference: The Height sensor measures the distance
from the headrope to the bottom. If you use the PI54 echo
sounder, set Height reference to Bottom (default), and the
height marker will follow the bottom contour. If you even
define the delay correctly, you will be able to see the trawl in
true motion. If you do not have en active echo sounder, set
Height reference to Surface. The height will then be shown
with 0 m depth as reference, and the marker line will appear
as a nearly straight line some distance below 0 meters. The
distance from the 0 meter line and down to the marker line
will be the current height of the trawl.

3 Press the GAIN+ button until the Marker line setup
dialogue appears.
4 Observe the list of sensors. Only the sensors capable of

Trawl calculator
In order to calculate the correct delay, we suggest that you use
the built-in Trawl calculator. Observe the following procedure:
1 Press the GAIN+ button to access the Trawl calculator
setup page.
2 Set Trawl calculator mode to Auto.
3 Set Towing speed to Auto.
- In order to retrieve speed information, the relevant
equipment (GPS) must be interfaced to your PI54.
- When you read the speed information from a GPS, the
information is very accurate. Due to the fact that the
trawl calculations are made continuously, even the
slightest change in speed will be reflected on the
display presentation, and you may experience that the
markers fluctuate. If this is a pr oblem, enter the
average vessel speed manually.
4 If you run a pelagic trawl, set Trawl depth to Manual,
and enter the mean depth.
5 If you run a bottom trawl, you can set the Trawl depth to
Bottom, and read the depth from the echo sounder.
- If a transducer is connected to the PI54, the trawl
calculator will update the delay based on the data from
the echo sounder.
6 Enter the Wire length. In most cases, this is the length
from the stern of the vessel to the trawl doors.
7 Enter the Wire length offset. This is the distance from the
trawl doors to the headrope, and normally a fixed value.
The calculator will add the wire length to the wire length
offset, and use the sum of these in the calculations.

Depth and Height marker lines
The purpose of these marker lines is to provide an easy way to
monitor the depth of the gear. The Height sensor measures the
distance from the seabed and up to the sensor, while the Depth
sensor measures the distance from the sea surface and down to
the sensor.
1 Identify which of the sensors that are the Depth and/or
Height sensors.
2 For each sensor, set Auto to On.
- This enables the PI54 to use the delay calculated by t he
Trawl calculator.
- You can also set Auto to Off. You must then calculate
the delay yourself, and enter it manually in the Delay
column.
3 Enter your preferred value for marker line Width.
4 Enable each individual marker line by setting Show to

If the trawl door distance is reduced or increased, this will be
easily detected as the marker line moves up or down. Note that
you do not monitor the depth of the trawl doors even though
you use the depth scale, the scale is used as a range scale.
Surface temperature marker line
The purpose of this marker line is to provide an easy way to
monitor the surface temperature. Note that this is NOT a reading
from a temperature sensor, but from a feeler. Such feelers are
often built into the echo sounder transducers.
1 Ensure that a proper feeler is connected to the PI54.

Special features for trawl marker lines
When you have chosen a graphic presentation, you can choose
to superimpose the information from the echo sounder, and then
add marker lines to see where your sensors are located in
relation to the bottom and fish echoes. When you use a pelagic
or bottom trawl, the PI54 offers certain special features to
provide additional information.
(A) = Numeric depth display, Sensor “6D” placed on the
headrope
(B) = Marker line from the footrope, added by using the Manual
trawl marker setting
(C) = Marker line from the headrope using the data from Depth
sensor “6D”
The recommended sensor configuration to monitor the trawl
opening is to use one Height or Depth sensor on the headrope,
and one Depth sensor on the footrope. However, if you only use
one of these sensors, place it on the headrope. The PI54 will
then manually draw the trawl opening markers for you provided
that you enter the typical height of the trawl opening.
The following parameters will provide the extra information
related to trawl markers:
• Headrope and footrope sensors: You need to tell the PI54
which Depth and/or Height sensor(s) you have placed on the
footrope and/or headrope of the trawl.
Operational procedures
87
850-165186 / Rev.B
• Trawl opening mode: This parameter decides how the trawl
opening shall be recreated on the graphic presentation. If you
have sufficient sensors on the trawl you must select Auto,
and the the PI54 will automatically calculate the trawl
opening and draw it accordingly. If you only have one sensor
on the trawl opening (Depth or Height sensor on the
headrope), the Manual setting will add an artificial line on
the presentation. The distance from the headrope to the
footrope must then be defined manually using the Manual
trawl marker parameter.
Access to the parameters
1 Make sure that a graphic presentation is active.
2 Press the ADJ button to open the Graphic setup
dialogue.
3 Press the GAIN+ button to access the Trawl inf o setup

Set up the parameters
1 Locate the setting Headrope sensor, and choose the
sensor that you have placed on the headrope.
- If you have no Depth or Height sensors on the
headrope, leave the setting to None.
2 Locate the setting Footrope sensor, and chose the sensor
that you have placed on the footrope.
- If you have no Depth or Height sensors on the
footrope, leave the setting to None.
3 Observe that the setting for Trawl opening mode is
automatically set to Au to or Manual.
- If you have sensors placed on both the footrope and the
headrope, the PI54 will be able to calculate the trawl
opening automatically, and the mode is set to Auto.
- If you have only one sensor, you will need to enter a
manual trawl marker.
4 If you have only one sensor, enter a value for Manual
trawl marker.
- This value must represent the actual height of your
trawl opening, based on your knowledge about your
gear. The information will be used by the PI54 to draw
a second trawl marker line.

How to use visual aids and filters
When you use the echo sounder, several visual aids and filters
are available to make the echoes easier to read and interpret.
Ping to ping filter
This function employs a filter which compares the echo
information from one ping with the information from the
previous ping. This will “clean up” the echogram by r emoving
random noise spikes and interference with no correlation with
the previous echo. The function will thus make the echoes
appear more stable. You can switch this filter on or off.
1 Make sure that your echo sounder presentation is active.
2 Press the ADJ button to open setup dialogue.
3 Locate the Ping to ping filter parameter. Set it to ON.
Colour threshold
This function allows you to choose the number of colours to use
for echogram presentation. By switching this filter on and
selecting a colour in the box, all echo colours “below” the
chosen colour will not be shown in the echogram. You can thus
regard this as an “echo threshold” which will remove the
weakest echoes.
1 Make sure that your echo sounder presentation is active.
2 Press the ADJ button to open setup page
3 Locate the Colour threshold parameter. Set it to ON.
4 Select preferred colour in the box.
Signal threshold
This is an on/off function. When activated, it will remove the
weakest echoes from the screen. The threshold level is
automatic. Activate with caution, as it may remove small fish or
other weak unidentified echoes from the presentation.
1 Make sure that your echo sounder presentation is active.
2 Press the ADJ button to open setup page
3 Locate the Signal threshold parameter. Set it to ON.
Depth grid
When this function is enabled, thin horisontal depth lines will be
added to the echogram to easier identify the depth intervals.
1 Make sure that your echo sounder presentation is active.
2 Press the ADJ button to open setup page
3 Locate the Depth grid parameter. Set it to ON.

PRACTICAL USE OF THE SENSORS
The PI54 catch monitoring can operate with several different
sensors. In the following, the most important information
regarding installation and use of each sensor is described.
Both PI and PS sensors are described. The PI sensors have
longer ranges, they can be “fast-charged” using the PI Charger,
and they will provide some additional functionality. For all
other practical purposes the two types may be regarded as
identical. The PI54 system will automatically adapt to and work
with both types, and you can also use PS and PI sensors
together.

Communication channels and update rates
All sensors are provided from the factory with pre-defined
communication channels and update rates.
Sensor Com.channel Update rate

PI Depth (600 m) 12 Fast
PI Depth (1000 m) 10 Fast

Factory default communication channels and update rates
Changing a transmission channel
It may be required to change one or more transmission channels,
and there may be many reasons for this.
• You have more than one of each sensor. For example, if you
have three temperature sensors, they MUST communicate on
three different channels.
• Other vessels near your use the same PI54 system (or a
similar), and they have one or more of their sensors set up to
the same communication channels as you have. This will
create interference, as you will “read” each others sensors.
• If your sensors are set up to use communication channels too
close to each other (for example, you have chosen channels
4, 5 and 6), this will limit the vessel’s speed. The reason for
this is the doppler effect. If the speed is too high, the doppler
will cause the transmission frequencies to change so much
that they overlap, and this will create interference. The PI54
will provide a warning if this is about to happen! You must
then either change to other c ommunication channels further
apart, or reduce the maximum shooting speed.
• If you operate at the maximum range of the sensors, you may
be able to increase this range slightly if you use lower
communication channels. This is because the l ower
communication channels user lower transmission
frequencies.
Sensors
105
850-165186 / Rev.B
Changing the update rate
It may be required to change the update rate on a sensor, that is
how often it sends information back to the PI54 system. A high
update rate will give frequent information updates, but the
sensor will use more battery power. If you need your batteries to
last as long as possible, you must consider lowering the update
rate.
• A low update rate will provide you with fewer information
updates, but the battery will last very long.
• A high update rate will give you frequent information
updates, but the battery will run out faster.
All sensors are provided from Simrad with a default update rate
setting. In some cases you may find that this update rate does
not suit your operational needs. This is a decision you have to
make depending on the local fishing conditions.
How to change the sensor setup
To change the sensor setup, you can call your local Simrad
dealer, or you can do it yourself if you have the proper
equipment, training and the PI Configurator software.
The PI Configurator application is provided to enable local
sensor configuration. In order to perform this configuration, you
will need a personal computer (desktop or laptop) running
Microsoft® Windows® 2000 or Windows XP®, and a special
cable.
Special configuration of PI Spread
The PI Spread sensor is always used with a PI Remote sensor,
and these must be configured in a pair in order to make the
transverse communication link work properly. In order to allow
for a dual Spread application, you can use two predefined
configurations: PI Spread 1 and/or PI Spread 2.
The Remote sensors are available pre-programmed for these
two pairs, and the sensors are identified as Remote 1 and
Remote 2.
The two pairs must be configured as follows:
Configuration Spread sensor Remote sensor
PI Spread 1 PI Spread (*) Remote 1
PI Spread 2 PI Spread (*) Remote 2
(*) = The same PI Spread sensor is used for both configur-
ations. By default, it is programmed for PI Spread 1.Ifyou
wish to use it for PI Spread 2, you must re--configure it using
the PI Configurator application.
Simrad PI54
106
850-165186 / Rev.B
You can select the communication channels between the PI
Spread sensors and the vessel to suit your preferences.
Special configuration of PI Twin Spread
The PI Twin Spread sensor is always used with two PI Remote
sensors, and these must be configured as a group in order to
make the transverse communication links work properly. In
order to allow for a dual Spread application, you can use two
predefined configurations: PI Twin Spread 1 and/or PI Twin
Spread 2.
The Remote sensors are available pre-programmed for these
two pairs, and the sensors are identified as Remote 1, Remote
2, Remote 3 and Remote 2. The two first (1 and 2) are the same
sensors as for the standard PI Spread application.
The two groups must be configured as follows:
Configuration Spread sensor Remote sensors
PI Twin Spread 1 PI Twin Spread (*) Remote 1 Remote 3
PI Twin Spread 2 PI Twin Spread (*) Remote 2 Remote 4
(*) = The same PI Twin Spread sensor is used for both configurations.
By default, it is programmed for PI Twin Spread 1. If you wish to use it
for PI Twin Spread 2, you must re--configure it using the PI Configura-
tor application.
You can select the communication channels between the PI
Twin Spread sensors and the vessel to suit your preferences.

(B) = Positive charging / fastening lug
(C) = Communication link ( Channel 1 - 30)
(D) = Location of sensor lamp
(E) = Water switch sensor
(F) = Detection wire (in/out)
(G) = Ground weight
Daily operation
Once installed and put to use, the sensor will

waterswitch is activated. After an initial startup,
the sensor starts transmission of the detector wire
(F) status (in or out). When the sensor is not in
use, check that the sensor lamp (D) is not flashing
from time to time, as this indicaties that the
sensor is on and is discharging its batteries. In
this case, wash the sensor in fresh water to
remove salt and dirt.
If you operate with Fast update rate, t he sensor
must be charged approximately every 35 hours.
Used with Normal or Slow update rates, the
operational life is approximately 60 or 250 hours
respectively. The optimal sensor charging
temperature is from +10 to +25° C.

minutes the sensor has been “lifted
off” the bottom. It must be reset
manually.
(D) = Indicator, lit for every sensor
interrogation.
(E) = Interference symbol.
(F) = Sensor set up as sensor no.3.
(G) = Sensor has lost contact with
bottom. The timer starts. An audible
alarm may be enabled.
(H) = The timer shows how many
minutes the net has “lifted off”
during a tow.
Sensor configuration
On delivery, all Bottom Contact sensors are configured in
Channel 6 and with Normal update rate.
Note: The sensor and the PI54 system setup must correspond,
otherwise the communication will not work.
To change the sensor setup (channel selection, update rate etc),
use the PI Configurator utility.
The sensor update rate controls how often the sensor monitors
whether the gear is on of off the bottom. Th ree settings are
available. Note that a faster update rate will decrease the battery
life.
• Fast (~3,2 sec): Recommended for new trawl or gear , or
changes in rigging to monitor instabilities in ground gear
bottom contact.
Sensors
109
850-165186 / Rev.B
• Normal (~5,3 sec): Recommended for normal fishing.
• Slow (~33 sec): Recommended if maximum operational
battery life before charging is required. The system will be
more sensitive to bad communication conditions due to the
slow data update.
System configuration
Sensor configuration: The sensor must be configured with a
unique sensor number. Select update rate and channel number
according to the sensor’s configuration. Write down this
configuration for future reference.
Status & Receiver: The Interference filter must be switched on.
Set it to level 9 if you have noise problems from other
hydroacoustic sources. Note that with the filter on, it will
influence the signal spectrum shown in the Status display.
Catch/Bottom sensor filter: Switch this filter off. Set it to
Light or Heavy only if you experience excessive noise.
Mounting
Location: Place the sensor where you
wish to monitor bottom contact. This
is normally in the center of the net.
Seize the attachment ring (A) for the
stay underneath the net, then put two
carabine hooks inside the footrope
forming a bridle of 15 to 20 cm
securely holding the sensor in a stable
position.
Penetration ring: Place the
penetration ring (B) for the detection
wire approximately 30 cm rear of the
footrope. Before final seizing, mount
the sensor to the carabine hooks and
check that t he detection wire (E)
passes trough the center of the
penetration ring (B). Remove any net
on the inside of the penetration r ing.
Simrad PI54
110
850-165186 / Rev.B
Set up: Correct function requires that the length of the stay (F)
and the detection chain (G) are trimmed with regard to each
other and the gear in use. Standard delivery includes a 63 cm
stay and 39 cm detection chain for use with 14 to 16 inch
bobbins or rock hoppers (C).

(K) = Bottom
(L) = Angle approximately 25°
Adjustment: Lay the sensor on an elevated surface. Adjust the
length of the detection chain (G) as necessary. Observe detection
wire (E) movement while simulating bottom contact by raising
the weight. Tilt the weight approximately 25° to compensate for
drag forces when towed through the water, and adjust the stay
length to be taut. To avoid damage, remove the weight before
coiling the gear on the drum.
Note: The sensor’s detection wire must always be allowed to pass
freely through the center of the penetration ring when it is
deployed. Attach the rubber straps so that the sensor is held
horizontally during towing.
Sacrificial water switch sensor
If the water switch on your sensor is a sacrificial brass screw,
this screw must be checked every month. Whenever required

sensitive to bad communication conditions due to the slow data
update.
System configuration
Sensor configuration: The sensor must be configured with a
unique sensor number. Select update rate and channel number
according to the sensor’s configuration. Write down this
configuration for future reference.
Status & Receiver: The Interference filter must be switched on.
Set it to level 9 if you have noise problems from other
hydroacoustic sources. Note that with the filter on, it will
influence the signal spectrum shown in the Status display.
Catch/Bottom sensor filter: Switch this filter off. Set it to
Light or Heavy only if you experience excessive noise.
Mounting
Location: Place the sensor where you
wish to monitor bottom contact. This
is normally in the center of the net.
Seize the attachment ring (A) for the
stay underneath the net, then put two
carabine hooks inside the footrope
forming a bridle of 15 to 20 cm
securely holding the sensor in a stable
position.
Penetration ring: Place the
penetration ring (B) for the detection
wire approximately 30 cm rear of the
footrope. Before final seizing, mount
the sensor to the carabine hooks and
check that t he detection wire (E)
passes trough the center of the
penetration ring (B). Remove any net
on the inside of the penetration r ing.

wire (E) movement while simulating bottom contact by raising
the weight. Tilt the weight approximately 25° to compensate for
drag forces when towed through the water, and adjust the stay
length to be taut. To avoid damage, remove the weight before
coiling the gear on the drum.
Note: The sensor’s detection wire must always be allowed to pass
freely through the center of the penetration ring when it is
deployed. Attach the rubber straps so that the sensor is held

PI Catch sensor
Purpose
The PI Catch sensor detects when the trawl has been filled with
fish. The sensor monitors the opening of the m eshes in the cod
end, and will be activated once the volume caught is enough to
pull the detector wires.
Catch sensor principle: Three sensors are
mounted at the cod end of the trawl to detect the
amount of fish caught.
Main parts
(A) = Negative charging / fastening lug
(B) = Positive charging / fastening lug
(C) = Communication link
(D) = Location of sensor lamp
(E) = Water switch sensor
(F) = Detection wires
Daily operation
To monitor the filling rate, we recommend that
you use minimum two sensors. The first sensor is
located at the far end of the cod-end indicating
that the trawl is fishing, while the second sensor
tells when to haul. Due to the f ish moving back
and forth in the cod-end, the sensor will normally
change status (on/off) several times until the
volume caught keeps the opening of the meshes
stable.
Simrad PI54
116
850-165186 / Rev.B
Once installed and put to use, the sensor will automatically be
switched on once the waterswitch is activated. After an initial
startup, the sensor starts transmission of the detection wires (F)
status (in or out). When the sensor is not in use, check that the
sensor lamp (D) is not flashing from time to time, as this
indicaties that the sensor is on and is discharging its batteries.
In this case, wash the sensor in fresh water to r emove salt and
dirt.
If you operate with Fast update rate, the sensor must be charged
approximately every 35 hours. Used with Normal or Slow
update rates, the operational life is approximately 150 or 300
hours respectively. The optimal sensor charging temperature is
from +10 to +25° C.
Note: Note that charging sensors at sub-zero temperatures can create
explosive gasses. Simrad AS assumes no liability for the
improper charging of sensors or the use of chargers not

Sensor configuration
On delivery, all Catch sensors are configured in Channel 4 and
with Normal update rate. If you use more than one Catch sensor,
make sure that you set them up to operate on different channels
and with different sensor numbers!
Note: The sensor and the PI54 system setup must correspond,
otherwise the communication will not work.
To change the sensor setup (channel selection, update rate etc),
use the PI Configurator utility.
The Catch sensor can be configured (using the PI Configurator
software) to act as a FA701 catch sensor. This will allow the
sensor to be used with the Simrad FS trawl sonar. The
communication channel on the FS sonar must be set up to
correspond to the equivalent sensor number (1, 2 3 or 4).
The sensor update rate controls how often the amount of fish
caught is measured and transmitted to the vessel. Three settings
are available. Note that a faster update rate will decrease the
battery life.
• Fast (~5,3 sec): Recommended for trawling in areas where
the rate of filling is very high. Use this setting to avoid
damage to the trawl or excessive catches.
• Normal (~33 sec): Recommended for normal fishing.
• Slow (~125 sec): Recommended if maximum operational
battery life before charging is required. The system will be
more sensitive to bad communication conditions due to the
slow data update.
When the Catch sensor is configured as an FA701, it will have a
constant update rate of approximately 80 seconds. This rate
must not be changed.
System configuration
Sensor configuration: The sensor must be configured with a

Location: Attach the sensor on top of the cod-end where the
catch is to be monitored. As the cod-end fills, the net’s meshes
will open pulling the detector wires and thus activating the
sensor.
Sensor attachment to a net with an approximate mesh size of 140 mm. The distance
between the anchor points for the attachment rings and rubber straps will vary

(C) = Nylon attachment rings bent to the net
(D) = Detection wires
(E) = Rubber strap
(F) = Attachment point
Attachment: The Catch sensor’s orientation towards the vessel
is maintained by the steel and nylon attachment rings. The
number of meshes the attachment rings are supported between
must be restricted to avoid unnecessary stress on the s ensors
fastening lugs when the cod -end is filled to maximum. The use
of both nylon and steel attachment rings is required to secure the
sensor lugs if excessive forces are applied on them. The nylon
rings will stretch or break down, but the steel ring will prevent
the sensor from being lost. Note that two steel rings must be
mounted on the same side.

Sensitivity: The sensitivity of the Catch sensor is determined by
the number of meshes separating the rubber straps. You can
simulate this by stretching the net’s meshes to approximate the
mesh opening estimated to trigger the sensor. Mark the location
(with colored thread) for future references.
Rubber straps: Inspect the rubber straps regularly and always
before a new haul. Replace them if you detect visible signs of
cracks or damage.

sensor is normally attached to the
headrope (A). For secure fastening
and stable positioning of the sensor
pointing towards the vessel, make a
fine mesh bag (B) located at the
centre of the headrope. Size two snap
hooks (C) approximately 10 - 15 cm
from the headrope forming a bridle,
and keep the sensor stretched by
means of two rubber straps (D)
attached to the aft fastening lugs.

PI Height sensor
Purpose
The PI Height sensor monitors the current height of the trawl,
as well as the rate of any height changes. All measurements are
related to the bottom.
(A) = The PI Height sensor is normally
mounted on the headrope, and by means of
the built-in echo sounder it will measure the
distance t o the bottom.
(B) = Echo sounder transmission field
Main parts
(A) = Negative charging and fastening lug
(B) = Positive charging and fastening lug
(C) = Communication link
(D) = Location of sensor lamp
(E) = Water switch sensor
(F) = Echo sounder transducer - must be

850-165186 / Rev.B
Daily operation
Once installed and put to use, the Height sensor will
automatically be switched on once the waterswitch is activated.
After an initial startup, the sensor starts the echo sounder, and
the depth results are transmitted to the vessel. When the sensors
are not in use, check that the sensor lamp (D) do not flash from
time to time, as this indicates that the sensor is on and is
discharging its batteries. In this case, wash the sensor in fresh
water to remove salt and dirt.
If you operate with Fast update rate, t he sensors must be
charged approximately every 35 hours. Used with Normal or
Slow update rates, the operational life is approximately 60 or
250 hours respectively. The optimal sensor charging t emperature
is from +10 to +25°C. The sensor can only be charged with the
PI Charger.
Note: Charging sensors at sub-zero temperatures can create explosive
gasses. Simrad AS assumes no liability for the improper
charging of sensors or the use of chargers not specified in
Simrad’s sensor charging documentation.
Numerical presentation
On the PI54 display, the distance to the bottom is displayed in
the numeric display. If the height is increasing or decreasing,
this is shown with two arrows and the variation in meters per
second. When the readings are stable, the digits are shown in
black colour. When the values are predicted, the digits are grey,
and if the contact is lost, the characters *.* * are shown in grey.
(A) = Sensor set up as sensor no.1.
(B) = Height measured in meters.
(C) = Current distance from t he

Sensor configuration
On delivery, all Height sensors are configured in Channel 14
and with Fast update rate.
Note: The sensor and the PI54 system setup must correspond,
otherwise the communication will not work.
To change the sensor setup (channel selection), use the PI
Configurator utility.
The sensor update rate controls how often the sensor reads and
reports the height. Three settings are available. Note that a faster
update rate will decrease the battery life.
• Fast (~5,5 sec): Recommended for new trawl or changes in
rigging to monitor any instabilities or unexpected changes.
This mode provides the shortest battery life before charging.
• Normal (~14 sec): Recommended for well known trawl
behavior with stable situations. Use this setting during
normal conditions.
• Slow (~34 sec): Recommended to monitoring a stable
situation over time. The system will be more sensitive to bad
communication conditions due to the slow data update. This
mode provides longest operational battery life before
charging.
System configuration
Sensor configuration: The sensor must be configured with a
unique sensor number. Select channel number and update rate
according to the sensor’s configuration. Write down the
configuration for future reference.
Status & Receiver: The Interference filter must be switched on.
Set it to level 9 if you have noise problems from other
hydroacoustic sources. Note that with the filter on, it will
influence the signal spectrum shown in the Status display.
Sensor filter: Switch this filter to Light. Set it to Heavy only if
you experience excessive noise. Position Off will provide raw
data and fastest possible response.

Mounting
Location: Place the sensor where you wish to monitor the
height. This i s normally aft of the headrope at the center of the
net.
Ensure that you mount the sensor with the reverse side (D) and
the echo sounder transducer (E) pointing towards the bottom!
The SIMRAD print on the sensor (C) must point up towards the
water surface!
Mounting: Secure the two forward
fastening lugs (A) using two snap
hooks and rope. Then, secure the two
aft fastening lugs (B) using snap
hooks and strong rubber bands. This
mounting places the sensor i n a cradle
supported on all four sides.
In order to secure the sensor in place,
we recommend that you assemble a
bag of fine-meshed net, and ties this
to the trawl close to the middle of the
headrope. Then, mount the sensor
inside this bag. The sensor must be
properly secured to prevent it from
moving sideways or rotate during use.

PI Rip sensor
Purpose
The PI Rip sensor is identical to the PI Catch, and it must be
regarded as a second application for the Catch sensor. The PI
Rip sensor will monitor if your net is damaged and ripped apart
due to obstructions or foreign objects on the seabed.
(A) = The PI Rip is mounted on the footrope with
the two sensor wires stretched out and the wires
engaged.

Once installed and put to use, the sensor will automatically be
switched on once the waterswitch is activated. After an initial
startup, the sensor will detect the status of the detection wires,
and transmit this information to the vessel. When the sensor is
not in use, check that the sensor lamps (D) do not flash from
time to time, as this indicates that the sensor is on and is
discharging its batteries. In this case, wash the sensor in fresh
water to remove salt and dirt.
If you operate with Fast update rate, t he sensors must be
charged approximately every 35 hours. Used with Normal or
Slow update rates, the operational life is approximately 150 or
300 hours respectively. The optimal sensor charging t emperature
is from +10 to +25° C.
Note: Note that charging sensors at sub-zero temperatures can create
explosive gasses. Simrad AS assumes no liability for the
improper charging of sensors or the use of chargers not
specified in Simrad’s sensor charging documentation.
Numeric presentation
On the PI54 display, the Rip sensor status is displayed with
graphic symbols. The timers count the total number of minutes
the sensor has been activated (red rectangle). If only predicted
timer values exist, the timer characters are shown in grey. If the
sensor communication is lost, the graphic symbol is replaced by
the characters ***.* (in grey).

Sensor configuration
On delivery, all Rip sensors are configured in Channel 4 and
with Normal update rate. If you wish to use Rip and Catch
sensors simultanously, one of them must be set to a different
communication channel.
Note: The sensor and the PI54 system setup must correspond,
otherwise the communication will not work.
To change the sensor setup (channel selection), use the PI
Configurator utility.
The sensor update rate controls how often the sensor reads and
reports the condition of the net. Three settings are available.
Note that a faster update rate will decrease the battery life.
• Fast ( ~5,3 sec): Recommended if you suspect that the bottom
conditions are rough and unpredicatble, and that damage may
be easily inflicted. This mode provides the shortest battery
life before charging.
• Normal (~33 sec): Recommended for normal bottom
conditions.
• Slow (~125 sec): Recommended if the bottom conditions are
well known, and you know that no obstructions exist. This
mode provides longest operational battery life before
charging.

Location: Place the sensor where you wish to check the net
condition. This is normally close to the footrope at the center of
the net. If the net is torn, the slack will release one or both of the
sensor’s detection wires.
Rip sensor attachment to the net, location just aft of the footrope. The distance between
the anchor points for the attachment rings and rubber straps must be defined depending
on the size of the net and how large area you wish to monitor.

850-165186 / Rev.B
Attachment: The sensor’s orientation towards the vessel is
maintained by the steel and nylon attachment rings. The number
of meshes the attachment rings are supported between must be
restricted to avoid unnecessary stress on the s ensors fastening
lugs. The use of both nylon and steel attachment rings is
required to secure the sensor lugs if excessive forces are applied
on them. The nylon rings will stretch or break down, but the
steel ring will prevent the sensor from being lost. Note that two
steel rings must be mounted on the same side of the sensor.
Rubber straps: The two rubber bands (E) must be stretched
towards aft, and mounted to the meshes in such a way that the
detection wires are engaged during normal operations. The
angle between the two rubber bands should be approximately 70
degrees. Inspect the rubber straps regularly and always before a
new haul. Replace them if you detect visible signs of cracks or
damage.

After an initial startup, the sensor starts interrogating the
Remote s ensor to measure the distance. The results are
transmitted to the vessel. When the sensors are not in use, check
that the sensor lamps (D) do not flash from time to time, as this
indicates that the sensor is on and is discharging its batteries.
If you operate with Fast update rate, t he sensors must be
charged approximately every 45 hours. Used with Normal or
Slow update rates, the operational life is approximately 100 or
150 hours respectively. The optimal sensor charging t emperature
is from +10 to +25° C.
Note: The two rubber inserts provided at the bottom of each sensor
adapter must not be replaced with any other types or designs. It
is essential that these inserts provide a secure cradle for the
sensors, but they must also allow for free water circulation to
allow the sensor’s water switch to engage. Also, the design of
the inserts allows sand and mud to flow out when the trawl
doors are pulled up from the water.

that the sensor lamp ( D) is not flashing from time
to time, as this indicates that the sensor is on and
is discharging its batteries.
You can only operate this sensor with Fast update
rate. The sensor must then be charged
approximately every 30 hours. The optimal
sensor charging temperature is from +10 to
+25°C.
Note that charging sens ors at sub-zero temperatures can create
explosive gasses. Simrad AS assumes no liability for the
improper charging of sensors or the use of chargers not specified
in Simrad’s sensor charging documentation.

Sensor configuration
On delivery, all temper ature sensors are configured in Channel 8
and with Fast update rate. It is not possible to change the update
rate setting. If you use more than one sensor, you must set them
up to operate in different channels.
Note: The sensor and the PI54 system setup must correspond,
otherwise the communication will not work.
To change the sensor setup (channel selection), use the PI
Configurator utility.
The sensor update rate controls how often the temperature is
measured, and the data transmitted to the vessel. To be able to
monitor fast changes in the sea temperature, the sensor will only
operate on Fast update rate.
System configuration
Sensor configuration: The sensor must be configured with a
unique sensor number. Select channel number according to the
sensor’s configuration. Write down the configuration for future
reference.
Status & Receiver: The Interference filter must be switched on.
Set it to level 9 if you have noise problems from other
hydroacoustic sources. Note that with the filter on, it will
influence the signal spectrum shown in the Status display.
Sensor filter: Switch this filter to Light. Set it to Heavy only if
you experience excessive noise. Position Off will provide raw
data and fastest possible response.

Purse seine: In order to secure stable communication with the
vessel’s hydrophone, it is very important that the sensor is
allowed to hang freely with the top end pointing towards the
surface during shooting and pursing.
Attach the sensor to a standard purse
ring with two separate wires (A).
Mount one end of each wire to a
common snap hook (B), and place
another snap hook at the other end of
each wire to snap onto the sensor.
Mount a safety line (C) between the

SENSOR CHARGERS
Overview
Two different battery chargers can be used to charge the PI and
PS sensors:
• PI Charger
• PS30 Charger
Even though both chargers can be used to charge any of the
sensors (except the PI Height sensor), only the PI Charger will
provide fast and intelligent charging of the PI sensors.
Note: The PI Height sensor can only be charged with the PI Charger.

PI Charger
Purpose
The PI Charger is an intelligent battery charger for fast and
secure charging of the PI sensors. The charger will
automatically set up the correct charging current depending on
the sensor type and the battery temperature. Even though the PI
Charger is designed for fast charge of the PI sensors, it can also
charge the PS sensors, but only at normal charge rate. A fuel
meter shows the status of the battery during the charge.
Daily operation
1) Attach the charging clamps to the sensor as
follows:
Red clamp: Positive fastening lug (+)
Black clamp: Negative fastening lug ( -)
2) Ensure that attachment materials, rope etc. do not
short circuit the charging lugs, preventing charging
and causing damage to the sensor lugs.
Once connected, the charger will identify whether
the sensor connected can be fast charged or not.
The battery temperature will always be monitored
for a fast charging sensor. A sensor which can not
be fast charged, will not display the battery
temperature, and the temperature LED will be
dark.
3) Observe the charge times and temperature limitations:
Fast charge: First approximately 1 hour for 70% battery
capacity, then approximately 3 hours to reach 100% capacity.
Once fully charged, a constant trickle charge will compensate
for self discharging. Note that fast charging applies to PI
sensors only!
Normal charge: 16 hours for full battery capacity. This
mode applies for charging outside specified temeparture
range, and for all PS sensors.
Charging temperature: For best res ults, keep the ambient
temperature between +10 and +25°C. Do not charge in
temperatures above +50°C or below 0°C!

Green and Blue: Battery temperature between 0 and +5°C.
Fast charge is disabled, normal charge is used.
Green and Red: Battery temperature between +40 and
+50°C. Fast charg disabled, normal charge is used.
Blue: Battery temperature is below 0°C. No charging takes
place.
Red: Battery temperature is above +50°C. No charging takes
place.
Warning: Charging a sensor at sub-zero temperature might
develop explosive gases r epresenting a potential
danger. Simrad assumes no liability for improper
charging, o r the use of other chargers than those
approved by Simrad.
Automatic configuration
The charger communicates with the sensor at regular i ntervals.
The fast charge cycle is controlled by data exchanged between
the PI sensor and the charger, and a series of safety mechanisms
controls the termination of the fast charging current.
The PS sensors do not communicate with the charger. A
constant charge current of 58 mA is then set up by the charger
regardless of the battery temperature.

Purpose
The PS Charger is a battery charger for secure charging of the
PS and PI sensors.
Daily operation
1) Attach the charging clamps to the sensor as follows:

Black clamp: Negative fastening lug (-)
2) Ensure that attachment materials, rope etc. does not short
circuit the charging lugs, preventing charging and causing
damage to the sensor lugs.
3) Observe the sensor’s indiactor lamp. It will flash once every
four seconds during charging.
4) Observe the charge times and temperature limitations:
Normal charge: ~16 hours for full battery capacity.
Charging temperature: To obtain best results, try to keep
the ambient temperature between +10°C and +25°C. The
sensor must not be charged in temperatures above +50°C or
below 0°C!
Warning: Charging a sensor at sub-zero temperature might
develop explosive gases r epresenting a potential
danger. Simrad assumes no liability for improper
charging, o r the use of other chargers than those
approved by Simrad.

General guidelines
Operational time and service life of the sensor’s NiCd battery
depends on proper use and regular charging. Observe the
following precautions, as these will have an influence on the
battery performance:
• Observe the charging temperatures.
• Charge sensors regularly. Avoid draining the sensor battery
completely before charging.
• Charge the sensor battery before storage, and at three-month
intervals under long-term storage.
• Operational life may be initially reduced after long-term
storage or charging f or a long time.
• Sensors are not damaged by being left attached to a charger
for several days. However, do not store the sensor for
extended periods under charge.
• We recommend that a wooden box is made to keep the sensor
in a secure place during charging and storage. Make openings
in the bottom to drain for sea water.
Battery depleted frequently
If the charger lamp is illuminated, but the sensor l amp does not
flash every four seconds, the battery is not being charged
properly. Most likely, this is because the sensor was not
switched off when the charger was connected.
To correct, charge the sensor for ten minutes, then disconnect
the alligator clips. Use a small wire, and make contact between
the water switch sensor and one of the fastening lugs. This will
cause the sensor to flash its start-up code. If not, wash the sensor
in fresh water to disengage the water switch.

Depth calibration
This function is used t o enable calibration of the PI54 Depth
sensor.
To access this function, press the MENU button to open the
main menu. Then, open the Setup menu, and select Sensor
alarm/calibration .
When the dialogue opens, press the GAIN+ button a few times
to open the Depth calibration dialogue.
The Depth calibration feature will calibrate the current depth
of the Depth sensor to one -1- meter.
1 Lower the sensor over the side to a depth of one meter, to
a certain draft depth pl us one me ter, or to any reference
level that you wish to be defined as one meter.
2 Once the reading from the sensor is stable, set Depth
sensor calibration to YES.
The calibration takes one minute. While the process is running,
the numerical pr esentation is shown with grey text. Note that the
sensor must be submerged into salt water to perform the
calibration.

Echo presentation setup
These settings are used to set up the echo sounder presentation
parameters on the PI54. The operational parameters are set up
using t he Echo sounder setup dialogue.
To access the parameters, press the ADJ (Adjust) button when
you have an echo sounder presentation in the active window.
You can also press the ENT button, and then select Echo
presentation setup on the Echo quick menu.
Range start: This is the upper depth from which you wish the
echo sounder shall start. This value will typically be 0 meters,
but you may for example set up the echo sounder to only present
echoes from 5 meters below the sea surface and downwards.
Range: This is the vertical depth range for the echo sounder.
You can set it to change depth range automaticially (AUTO), or
you can define your own fixed range. The maximum range will
depend on the chosen echo sounder frequency, as the 38 or 50
kHz modes will detect echoes deeper than the 200 kHz mode.
Gain: This is the gain in the echo sounder’s preamplifier. The
gain must be defined manually, and you can choose any value
between 1 and 100%. In most cases, use a value around 60%. If
you use too much gain, the echogram will contain a lot of noise
and false echoes.
White line: This parameter allows you to switch the White line
function on or off. When enabled, a band in the current
echogram background colour is inserted immediately below the
detected bottom depth.
Simrad PI54
178
850-165186 / Rev.B
Expansion window: The PI54 provides bottom expansion and
zoom functions. When one of these is enabled, you can control
the depth range in the expanded window using this parameter.
To enable the bottom expansion function, press the B-LCK
button on the keypad. To enable the zoom function, press the
ZOOM button. To disable both, press the STND or SHIFT
buttons. You can also access this parameter in t he Graphic
setup.
TVG (Time Varying Gain): The PI54 provides a TVG function
to enhance the echoes from deeper waters. You can switch the
TVG to OFF (not recommened), or select either Special (40 log
R) or Normal (20 log R) setting, depending on your preferences.
For all normal operation, leave it at Normal. Try Special if you
are looking for echoes close to the seabed in deeper waters.
Ping to ping filter: This function employs a filter which
compares the echo information from one ping with the
information from the previous ping. This will “clean up” the
echogram by removing random noise spikes and interference
with no correlation with the previous echo. The function will
thus make the echoes appear more stable. You can switch this
filter on or off.
Signal threshold: This is an on/off function. When activated, it
will remove the weakest echoes from the screen. The threshold
level is automatic. Activate with caution, as it may remove
small fish or other weak unidentified echoes from the
presentation.
Colour threshold: This function allows you to choose the
number of colours t o use for echogram presentation. By
switching this filter on and selecting a colour in the box, all
echo colours “below” the chosen colour will not be shown in the
echogram. You can thus regard this as an “echo threshold”
which will remove the weakest echoes.
Depth grid: When this function is enabled, thin horisontal depth
lines will be added to the echogram to easier identify the depth
intervals. When you operate with a graphic display, this function
can also be switched on and off in the Graphic setup.
Transmit pulse length: This parameter allows you to choose
the length of the echo sounder pulse transmissions. You can
choose OFF (to observe the ambient sea noise), SHORT,
MEDIUM, LONG or AUTO. In most cases, select AUTO. The
PI54 will then automatically choose the pulse length depending
on your current depth range. If you choose to try a manual
mode, try long pulse lengths when you operate in deeper waters,
and shorter pulses with higher frequency in shallower waters.
References
179
850-165186 / Rev.B
As a general rule, short pulses serve to make the echoes from
various objects more distinct. It is therefore used to obtain
optimal vertical resolution, as it will separate individual fishes
from each other and from the bottom. Longer pulses will
penetrate deeper, but with less resolution.
Transmit power: This parameter allows you to change the
power output from the echo sounder. You can choose OFF (and
no echogram will appear!), 10 W, 100 W, 500 W, 1000 W or
AUTO. In most cases, select AUTO. The echo sounder will then
automatically adjust the power output depending on the current
operational frequency and the current depth.
Scroll speed: This function controls how fast the presentation
shall scroll from right to left across the display. By def ining this
speed you also control the time scale. If you slow down the
scroll speed, you will also increase the time between each echo
sounder transmission (ping). If you choose FREEZE the
presentation (and also the echo sounder transmissions) will stop
altogether. N ote that this parameter can also be set in the
Graphic setup.
Note: The echo sounder frequency you choose must be supported by
the transducer you have installed!

PI54. This operation is only carried out once, and that is during
the system installation. DO NOT ADJUST t hese settings during
normal operation of the echo sounder, as incorrect settings may
result in damage to the PI54 and/or the transducer(s).
For more detailed information on transducer installation, consult
the PI54 installation manual.
Select transducer: Enter the type and main parameters of each
transducer connected to the PI54 system.
Transducer type: Enter transducer type. You can leaf through a
number of predefined transducer types, or defi ne your own.
Note that some of the predefined types are “dual” transducers,
which means that both transceiver outputs ports (Echo1 and

Transducer port: Enter which transceiver port (output) the
transducer is connected to; Echo1 or Echo2. With the predefined
transducer types, the ports are also set by the software.
Transducer beam angle: Enter the fore -and-aft and
athwartships beam angles for the transducer. With the
predefined transducer types, this information is already known.
Transducer depth: Enter the vertical distance between the
transducer face and the water surface. Normally, this value can
be fixed, but if it changes considerably when the vessel is
loaded, you may need to change it. The value is used to provide
you with a correct depth under keel (DK) value in the echo
sounder presentation.
Echo sounder parameters
Keel depth below surface: Enter the distance between the keel
and the water surface. Normally, this value can be fixed, but if it
changes considerably when the vessel is loaded, you may need
to change it. This parameter is used to provide you with the
correct depth below keel value in the echo sounder presentation.
Data on NMEA-out from: Choose if the echo sounder data
output on the NMEA interface shall be taken from the 38 kHz,
50 kHz or 200 kHz echo sounder frequency.
Alarm for fish, strength: This parameter enables the fish
detection alarm, and adjusts the sensitivity (strength). With high
sensitivity, smaller fish (with weaker echoes) will trigger the
alarm.
DepthDSfish:This parameter allows you to define a vertical
depth area (between a maximum and a minimum depth) in
which the fish alarm can be triggered. Echoes outside the chosen
area will not trigger the alarm.
Depth DK alarm (minimum and maximum values): This
parameter enables an alarm t o sound off if the water depth under
the keel is shallower or deeper than two predefined limits.
Water profile: This parameter sets up the echo sounder for
operation in fresh or salt water.
Velocity of sound in water: This parameter allows you to fine
tune the performance of the PI54 echo sounder to the speed of
sound in the water. However, in most cases, the accurate speed
is not known, and this parameter is not important at all when
operating in shallow waters. For all practical purposes, leave
this setting to the default value of 1470 m/s.
Time scale: This parameter allows you to switch the time scale
in the echo sounder presentation on or off.

Restart of AUTO pulse/power: If you have set the transmit
power and pulse length parameters to Auto, the echo sounder
will automatically restart the parameters at fixed intervals to
ensure correct settings. By means of this parameter, you can
control the intervals. In most cases, leave this setting to 20
seconds, which is the default value.
Echo sampling: Using this function, you can select if the

Graphic setup
These settings are used to set up the PI54 parameters related to
the Graphic display.
The Graphic display shows the data from the sensors i n their
alphanumerical presentations, as well as historical plots
sumperimposed on the echogram. The digits in the
alphanumerical presentations are black when the data are valid,
they are grey when the values are only predicted, or they are
replaced with asterix characters (*) when the contact with the
sensor is lost. The yellow pulse lamp is lit every time
information in received back from the sensor. The positioning of
the alphanumerical presentations is controlled by the order of
which the sensors were configured in the Sensor setup
dialogue.
To access the parameters, press the ADJ button when you have
a graphic display in the active window. You can also press the
MENU button to access the Echo quick menu, and then select
Graphic setup.
Superimpose echo sounder: When activated, the presentation
from the echo sounder is added to the graphic display. Note that
this option is only valid if you have the echo sounder
transducer(s) installed, and the echo sounder is set up for normal
operation. You can only switch this function on or off.
Scroll speed: This function controls how fast the presentation
shall scroll from right to left across the display. By def ining this
speed you also control the time scale. If you slow down the
scroll speed, you will also increase the time between each echo
sounder transmission (ping). If you choose FREEZE the
presentation (and also the echo sounder transmissions) will stop
altogether. N ote that this parameter can also be set in the Echo
pres entation setup.

Additional information: The f eature will display an
information bar below the numeric presentations on the Graphic
display. The bar provides key technical pararameters related to
the echo sounder operation; frequency, output power and pulse
length. It will also show you the ambient air temperature, the
vessel’s speed and the current depth. If you use the selector pad
to adjust the depth of the VRM (Variable range marker) or the
echo sounder receiver gain, it will show you the current depth
and gain settings while you do this. The default setting is ON.
Depth grid: When this function is enabled, thin horisontal depth
lines will be added to the presentation to easier identify the
depth intervals. Note that this function can also be switched on
and off in the Echo presentation setup.
Data window sensors: When you have set up the Graphic
display on only a half screen, there is not space for more than
three sensor presentation rectangles at the top of the display.
With this parameter, you can choose if you wish to see sensors
1,2and3or4, 5 and 6. When you have set up the Graphic
display on a full screen, this parameter is not visible.
Echo strength colour scale: This parameter allows you to
switch t he echo strength colour scale on the left side of the
Graphic display presentation on or off. A turquoise colour
indicates the weakest echoes, while dark red i ndicates the
strongest echoes. Note that this colour scale can not be enabled
simultanously with the temperature scale.
Time scale: This parameter allows you to switch the time scale
in the Graphic display presentation o n or off. When enabled, it
is positioned immediately above the echogram. Note that the
time scale r elies on the chosen scroll speed: a low speed results
in a long time scale and vice versa.
Expansion window: The PI54 provides bottom expansion and
zoom functions. When one of these is enabled, you can control
the depth range in the expanded window using this parameter.
To enable the bottom expansion function, press the B-LCK

Interface setup
These settings are used to set up the PI54 parameters related to
the communication to and from peripheral units. To access the
parameters, press the MENU button to access the main menu.
Then, select Interface setup on the Setup menu.
Note: The parameters in the Interface setup will normally only be
accessed during system installation. If you change any of these
parameters during normal operation, your system may not be
able to communicate with external devices, and this may lead to
operational degradation.
Background
By means of the connectors on the rear side of the PI54 cabinet,
it can communicate with several peripheral devices. This is
useful, as it allows you to export and import information to and
from these devices. In order to establish this communication, the
devices on each end of the cable must speak the same
“language”. The National Marine Electronics Association
(NMEA) has defined communication standards f or maritime
electronic equipment, and the PI54 system conf orms to these
standards. The most common standard is NMEA 0183, and the
National Marine Electronics Association describes it as follows:
“The NMEA 0183 Interface Standard defines electrical signal
requirements, data transmission protocol and time, and specific
sentence formats for a 4800-baud serial data bus. Each bus may
have only one talker but many listeners.” For more information
about the National Marine Electronics Association and the
NMEA 0183 standard, refer to the organization’s web pages at
www.nmea.org
.
Telegrams
To move information between two electronic units, the data are
collected in telegrams
. The content (protocol) of each telegram
is defined by the NMEA standard, and several telegram types
exist to allow different type of data to be distributed. Unless you
wish to write your own software, you do not need to know how
these t elegrams are designed. However, whenever you set up
equipment interfaces, you need to ensure that each system on
your communication line is set up to send and receive the same
telegram. The standard allows one system to send data (a
“talker”) and several others to receive data simultanously
(”listeners”) on the same line. Therefore, you must ensure that
all products receiving data on a communication line is set up to
receive the same telegram(s) that the transmitting product
provides.

The Marker line s etup controls how the markers from the
applicable sensors are displayed on the Graphic display. The
setup function will read the current sensor configuration, and list
the relevant sensors on the menu.
In the example provided, the PI54 is set up with two Depth
sensors, one Height sensor, as well as input from a surface
temperature feeler. These will all provide information to the
graphic display. Those sensors that will not provide presentable
information will not be listed.
Note: The Ca tch and Bottom Contact sensors will not be able to
provide information for such markers, as they only trigger
on/off.
Auto: This option allows you to enable and use the delay
automatically calculated by the Trawl calculator. Select On to
enable the function. The current delay is then shown with grey
characters, and the values can not be edited. If you select Off
you must enter the Delay values manually. Note that the Trawl

Delay: For each sensor marker, you can define a presentation
delay. The echogram information provided by the PI54 is from
directly below the hull, but the marker information come from
the sensors, which are positioned some distance away. You can
therefore calculate a delay (in minutes and seconds) manually
based on the wire length, towing depth and speed, and with this
delay place the marker at its correct location on the echogram.
You can also enable the Trawl calculator function, and have the
delay calculated automatically.
Width: For each sensor marker, you can define the width of the
marker line in pixels. The colour of the line will automatically
be set to the current background colour of the numeric
presentation of the sensor data. The default line width is 2
pixels.
Show: Switch the marker(s) on or off to suit your preferences
and need for information. Use the palette to define unique
colours in order to distingush the markers from each other.
Surface temperature: This parameter allows you to
superimpose a temperature curve on the graphic display. To read
the values, you need to enable the temperature scale in the
Graphic setup. You can change the width of the temperature
marker line, and choose a colour from the palette.
Sensor marker in expansion: With this setting active, the
Depth and Height marker lines are expanded, and thus easier to
read. This is a useful feature when the sensor is towed close to
the bottom, and it is particulary important f or the Height sensor.
Marker white zone: When enabled, white pixels are added
above and under the marker to make it easier to distinguish it
from the background colours.
Height marker in main echogram: If you have a Height
sensor on the top of a bottom trawl and the trawl opening is
small, it may be difficult to tell the Height marker from the
bottom echo. If this is the case, set this function to Off,and
view the Height marker in expanded mode only.

850-165186 / Rev.B
Height reference: The Height sensor measures the distance
from the headrope to the bottom. If you use the PI54 echo
sounder, set Height reference to Bottom (default), and the
height marker will follow the bottom contour. If you even
define the delay correctly, you will be able to see the trawl in
true motion. If you do not have en active echo sounder, set
Height reference to Surface. The height will then be shown
with 0 m depth as reference, and the m a rker line will appear as a
nearly straight line some distance below 0 meters. The distance
from the 0 meter line and down to the marker line will be the
current opening of the trawl.

Receiver setup
These settings are used to establish the communication
parameters between the PI54 and the sensors.
To access the parameters, press the MENU button to access the
Setup menu (4). Then, select Receiver setup (6). You need to
acknowledge the access with the ENT button before the
dialogue is displayed.
The Receiver setup parameters have a major influence on the
PI54 performance. The default settings are those we have found
to be the best for general use, but for individual i nstallations
optimized settings may enhance the performance.
Interference filter: When this filter is active it will remove
interference (noise and false echoes) from other echo sounders
and sonars in the t he vincinity of your own vessel. It may not
remove all interference, but in most cases you will find this
filter to be very efficient. If you suffer from poor range
performance, and the spectrum o n the Status Display is nearly
flat, this filter may also prove useful. A normal sensor will then
show up with a narrow peak at its dedicated frequency. This
filter is by default switched on and set to level 9, and will tend
to prioritize stronger signals.
Interference filter level: Use this setting to control t he strength
of the Interfer ence filter. 9 is the default value and the heaviest
filtering. Selecting 0 will hardly have any effect, and is really
equivalent with the f ilter switched off.

Sensor filter: The PI54 is designed to quickly update data.
After the sensors have been submerged, the receiver requires
only three consecutive pings from individual sensors to calculate
and display their respective information. However, if you
experience problems with the reception, you may also try this
filter: it will average the data received from the sensors. Light
filtering will average the data received by the last four pings,
while heavy filtering averages the data received by the last eight
pings. We recommend that you only use heavy filtering if there
are large fluctuations in the displayed data, or if the rate of
change is small. Reduced filtering shortens the delay between
updating the changes in sensor location and the corresponding
displayed information. Default setting is LIGHT.
Catch/Bottom Sensor filter: This filter is used to smooth out
the information from the Catch and Bottom Contact sensors.
When the filter is switched off any change in sensor status will
immediately be shown on the display. Set to LIGHT the change
in status must last and remain stable for at least two pi ngs before
the display is changed. When HEAVY filtering is applied the
change i n status must last and remain stable for at least four
pings before the change is shown on the PI54 display.
AGC (Automatic Gain Control): This function allows the PI54
to automatically control the receiver gain. The units reads and
interprets the received signal strength, and adjusts the gain
accordingly. During normal operation, ON is the recommended
(and default) setting.
Manual gain: If you decide to switch the AGC off you must set
the gain manually. This can be useful when you work at
maximum detection ranges with favourable noise levels. The
default setting is 0 dB, and you can adjust the gain in steps of
20 dB.
Multipath filter (MP filter): When you operate in an areas with
substantial r everberation due to bottom topography, or in
shallow waters, you may experience problems when consecutive
operating channels have been configured, but the corresponding
sensors are not in use. False signals and sporadic error values
can also be caused by other types of hydroacoustical equipment
operating on the PI54 frequency range. This filter has been
implemented to remedy for such interference problem. Default
setting is OFF.
Multipath filter level (MP f ilter level): When the Multipath
filter has been enabled, you can adjust the filter l evel in small
steps to correct the interference problem. Lower filter values
represent stronger filtering. It is best to experiment with this
parameter by reducing the value in steps of 3 dB until the
Simrad PI54
210
850-165186 / Rev.B
detection error disappears. Check that the signals from the
sensor in use are still being r eceived, if they are not, the filter
will not be of help in this particular situation. The f ilter’s
effectiveness i s both location and net specific. Therefore, the
same parameters will not necessary work in different areas or
using various types of nets. Default setting is 42 dB.
Detection Threshold (DT): This function will inhibit r eception
of the weakest signals. If you experience problems with
interference signals generating false data and all of the
configured sensors are operative (analogous with the Multipath
problem); increase the Detection Threhold value carefully in
steps of 1 dB. High values allow only strong sensor signals to be
detected. A lower threshold value will provide greater range if
conditions are optimal, but if too low, interference will be
detected. It is best to experiment with different values t o
determine which to employ.
Note: If the Detection Threshold (DT) value is set higher than 28 dB,
all signals will be prevented from being detected.
Max shooting speed: The PI 54 has a built in doppler
compensation function which is configured using this parameter.
The parameter and related function is however only relevant if
sensor data is desired while the purse seine is being deployed. It
has no effect once the vessel is stopped waiting for the net to
sink. Note that if you set this parameter too h igh, you can create
a conflict with the channel selection. Should this situation arise,
the following message will appear: Max shooting speed differs
from wanted, channels are set too close to each other.

Sensor alarms
These settings are used to set up the PI54 parameters related to
sensor alarms.
To access the parameters, press the MENU button to open the
main menu. Then, open the Setup menu, and select Sensor
alarm/calibration .
Each sensor has an individual alarm setting, and you can also
trigger alarms to warn you about sudden temperature changes
and shallow water. Whenever an alarm is triggered an audible
signal is provided, and a message on the display presents the
cause of the alarm. Unless the reason for the alarm is corrected,
or the alarm disabled, it will sound again after 20 seconds.
Due to the amount of choices available for the PI54, the alarm
parameters are organized in three dialogues.
• Sensor alarm : This dialogue allows you to defined alarms
related to the information provided by the sensors.
• Surface temperature: This dialogue allows you to set up
alarms to warn you about surface temperatures, and to
indicate sudden temperature changes.
• Clearance: This dialogue allows you to define alarms to
monitor if a trawl or towed object comes too close or too far
off the bottom.
The Sensor alarm/calibration choice on the Setup menu also
allows you to define parameters for depth calibration and offset.
These are explained separately.

Trawl calculator
These settings are used to set up the PI54 parameters related to
the Trawl calculator.
To access the parameters, press the ADJ button when you have
a graphic display in the active window. Then, press the GAIN+
button four times until the settings appear. You can also press
the MENU button to access the Echo quick menu, select
Graphic setup (8), and then press the GAIN+ button f our
times.
Purpose
The Trawl calculator is used when you have chosen to
superimpose sensor data onto the Graphic display. However, in
order to position the sensor marker correctly on the echogram,
you need to calculate the delay. This is because the echo sounder
information is provided by a transducer located under the vessel,
while the sensors are l ocated on the gear, which may be
positioned several hundred meters behind the vessel. To adjust
for this d elay, you must calculate the value (in minutes) based
on the vessel’s speed, the wire length and the depth of the gear.
You can do it manually and enter a Marker line d elay in the
Marker line setup dialogue, or you can leave the calculation to
the Trawl calculator.
For a complete procedure, refer to the Operational procedures
chapter.
Parameters
Trawl calculator mode: Select Auto or Manual. When
Selecting Auto allows you to retrieve or enter trawl data, and
the PI54 will perform the calculation. Selecting Manual
switches the Trawl calculator off.
Towing speed: Select Manual to enter the average vessel speed,
or Auto to allow the PI54 to retrieve the information
automatically. If you select Auto you can choose to read the
speed over ground (SPG) or the speed through water (STW).
Simrad PI54
222
850-165186 / Rev.B
Note: In order to retrieve speed information, the relevant equipment
(GPS) must be interfaced to your PI54.
When you read the speed information f rom a GPS, the
information is very accurate. Due to the fact that the trawl
calculations are made continuously, even the slightest change in
speed will be reflected on the display presentation, and you may
experience that the markers fluctuate. If this is a problem, enter
the average vessel speed manually.
Trawl depth: Select Manual to enter average trawl depth. If
you run a pelagic trawl, you must use this setting. Select
Bottom if you run a bottom trawl, and you expect the trawl
depth to be equal to the depth measured by the echo sounder.
Note that in order to update the calculator automatically, the
echo sounder must be operational providing valid depth data.
These are shown with grey characters.
Wire length: Enter the length of the trawl wire. In most cases,
this is the length from the stern of the vessel to the trawl doors.
Wire length offset: Enter the distance from the trawl doors to
the headrope. This is normally a fixed value. The calculator will
add the wire length to the wire length offset, and use the sum of
these in the calculations.
Calculated m arker delay: When in Auto mode, the delay is
shown in minutes and seconds.

PI CONFIGURATOR
Purpose
The purpose of the PI Configurator utility is to be able to
configure sensors so t hat they can operate on different
communication channels. Several PI equipped vessels may then
operate simultaneously in the same area without interference.
The utility also allows you to change the update rate on each
sensor. This is the time elapsed between each data transmission
from the sensor to the host PI system.

Basic information
Default sensor settings
PI and PS sensors are delivered from Simrad configured with
common default settings. When required, the individual sensors
may be re-configured with regard to:
• Communication channel
• LED control
• Ping control
• Data Update rate
• Remote
• Show channel with LED flash at start up
Who can configure PI sensors?
Sensor configuration is normally performed by authorized
Simrad technicians. However, individuals with basic computer
skills and access to the necessary equipment should not find it
difficult.
Programming modes
The PI Configurator configuration software has two
programming modes, Standard and Professional.
Note: It is highly recommended that the configuration of PI and PS
sensors in the Professional mode is only performed by skilled
and experienced pers onnel.
Necessary equipment
The following hard- and software is required to use the PI
Configurator utility:
• PI Configuration software
• A PC with Microsoft WindowsE 2000 or XP operating
system and a COM port (serial line).
• A sensor programming cable for either a stationary or
portable PC.
The sensor programming cables for stationary and portable
PCs are constructed differently and are not
interchangeable.

Factory default communication channels and update rates
Changing a transmission channel
It may be required to change one or more transmission channels,
and there may be many reasons for this.
• You have more than one of each sensor. For example, if you
have three temperature sensors, they MUST communicate on
three different channels.
• Other vessels near your use the same PI Configurator system
(or a similar), and they have one or more of their sensors set
up to the same communication channels as you have. This
will create interference, as you will “read” each others
sensors.
• If your sensors are set up to use communication channels too
close to each other (for example, you have chosen channels
4, 5 and 6), this will limit the vessel’s speed. The reason for
this is the doppler effect. If the speed is too high, the doppler
will cause the transmission frequencies to change so much
that they overlap, and this will create interference. The PI
Configurator will provide a warning if this is about to
happen! You must then either change to other communication
channels further apart, or reduce the maximum shooting
speed.
• If you operate at the maximum range of the sensors, you may
be able to increase this range slightly if you use lower
communication channels. This is because the l ower
communication channels user lower transmission
frequencies.
Simrad PI54

850-165186 / Rev.B
Changing the update rate
It may be required to change the update rate on a sensor, that is
how often it sends information back to the PI Configurator
system. A high update rate will give frequent information
updates, but the sensor will use m ore battery power. If you need
your batteries to last as long as possible, you must consider
lowering the update rate.
• A low update rate will provide you with fewer information
updates, but the battery will last very long.
• A high update rate will give you frequent information
updates, but the battery will run out faster.
All sensors are provided from Simrad with a default update rate
setting. In some cases you may find that this update rate does
not suit your operational needs. This is a decision you have to
make depending on the local fishing conditions.

Making a programming cable
Should a Simrad programming cable not be available, it is
possible to make an adequate substitution as described below.
It is only possible to make programming cables for stationary
computers. If you wish to use a portable computer the cable
must be ordered from Simrad. Some new stationary computers
have been found to provide the same output specifications as
portable computers using lower voltage on the serial line. On
these computer s, a “portable” cable is also required.
You will need the following parts:
• A 9-pin, Sub-D female connector
• Approximately one to two meters of 2-wire cable
• A 3 kohm resistor
• Two alligator clamps
The cable assembly procedure is as follows:
1 Connect pin number two of the 9-pin, Sub-D female
connector to one end of the positive (+) lead of the 2-wire
cable. At t he other end of the positive (+) lead, connect
the positive (red) alligator clamp.
2 Connect pin number five of the 9-pin, Sub-D female
connector to one end of the negative (-) lead of the 2-wire
cable. At the other end of the negative (-), connect the
negative ( black) alligator clamp.
3 Connect the 3 kohm resistor between pins number two and
three of the 9-pin, Sub-D female connector.
4 Check both alligator clamps and r espective pins for
continuity.

Testing on land
1 Connect the PI Service Hydrophone to the PI Operator
Unit.
2 Place the Spread and Remote sensors on a level surface
with their “transversal eyes” pointing towards each other
at a measured distance (one to three meters). Record this
distance.
3 Place the test hydrophone approximately five meters away
from both the Spread and Remote sensors.
4 Turn on the PI, and record the distance shown on its
display.
5 Multiply the recorded physical distance by a factor of 4.5
and compare it to the distance displayed by the PI.
- The physical distance between the two sensors
multiplied by 4.5 and t he displayed distance shown on
the PI should be almost identical.
Testing in water
1 Disconnect the PI Service hydrophone, and reconnect the
vessel’s normal hull mounted hydrophone.
2 Switch off the vessel’s echo sounders, sonars and other
hydroacoustical equipment to avoid interference.
3 Lower the Spread sensor (A) over the side of the vessel
with its head (C) pointing towards the hydrophone. Lower
it to minimum three meters.
4 Switch off the PI system’s interference f ilter, and observe
the numeric display.
- If the interference symbol is not
displayed, leave the
interference filter switched off to increase the system’s
range and performance.

271
850-165186 / Rev.B
Lower the two
sensors as shown,
and make sure that
the Spread sensor’s
head points towards
the vessel’s
hydrophone (C).
Also, make sure that
there is a free line of
sight for the
transverse
communication (D).
5 On the PI numeric display, verify that the reading is +++.
- This signifes that there is no communication between
the Spread and Remote sensors.
6 Lower the Remote sensor (B) over the opposite side of the
vessel with its head pointing in the same direction as the
Spread sensor. Lower it to the same depth as the Spread
sensor, and ensure that there is a free line of sight for the
transverse communication (D).
- If both sensors are suspended under the vessel at its
widest point, the physical distance between the Spread
and Remote sensors is equivalent to the vessel’s
maximum beam.
7 Observe the PI numeric display. The reading should be the
same as the physical distance (without any compensation)
between the two sensors.
Note: Should any problems arise during this procedure, check that the
type (1 or 2), communication channel and update rate have been
configured for both sensors.
8 Switch on the vessel’s echo sounders and other
hydroacoustical equipment used during normal fishing
operations.
9 Switch the PI54 interference filter on and off, and observe
the numeric display. If the interfer ence symbol is not

SOFTWARE UPDATES
Overview
You can update the operational software in the PI54 Operator
Unit yourself by following the procedures provided. There are
two different programs that must be updated independently:
• DPS (Digital Signal Processor)
• MMI (M an-Machine Interface)
The software can be distributed on CDs, by e-mail or by
downloading the files from Simrad’s website.
In order to perform the software updates, you will need a
personal computer with a serial line connector, and a special
upload cable.
Note: Even though the software update procedures are uncomplicated,
Simrad cannot be held responsible for errors or malfunctions
that may occur after a software update, if the update has not
been performed according to the procedures, or as a result of
technical problems during the upload process.

Safety measures
The following safety measures have been implemented to
minimize the risk of errors during the upload process.
• When the software is uploaded from the computer to the
PI54 cabinet, the data are stored in a scratch pad (buffer).
The data are not transferred to the Flash PROM (the
microprocessor’s storage area) until all software data have
been transferred correctly to the scratch pad.
Software updates
295
850-165186 / Rev.B
• If the interface cable is unplugged, or you loose power on the
computer and/or the PI54 cabinet during the upload process,
you can simply abort the upload and restart it. Error
messages will provide guidance.
• When the PI54 cabinet detects that software is uploaded, it
will automatically present a relevant information page, and
the keypad will be locked. It is not possible to switch off the
PI54 cabinet during the software upload, except by
disconnecting power.
Critical process
Once all the software data have been uploaded correctly to the
