Chapter 1 - Introduction
TracVision M3/M2 System Overview
Your TracVision M3/M2 system is a state-of-the-art, actively
stabilized antenna system that delivers live satellite TV to your
vessel’s audio/video entertainment system. A basic system is
illustrated below. A receiver wiring diagram is provided in
Appendix A on page 59.
Figure 1 TracVision M3/M2 System Diagram
The antenna uses integrated DVB technology to
quickly acquire and track the correct satellite,
switch between satellites, and send TV signals to
the interface box. The TracVision M2 acquires and
tracks the satellite while the vessel is moored,
either at the dock or at anchor. The TracVision M3
adds the capability to track the satellite while the
vessel is underway – its gyros keep the antenna
pointed at the satellite at all times.
The interface box allows you to set up and
control the system using its four
pushbuttons and LCD display. It also
supplies power to the antenna and delivers
satellite TV signals to your satellite TV receiver.

Chapter 1 - Introduction
Linear Satellite Signals
Your TracVision system is configured to receive linearly polarized
satellite signals. Satellites around the world (with the exception of
satellites in North America, which transmit circularly polarized
signals) transmit linear signals in vertical and horizontal “waves” that
are offset exactly 90º from each other. This orientation doubles the
bandwidth, allowing the satellite to deliver hundreds of channels of
digital entertainment to your vessel.
Figure 2 Linearly Polarized Satellite Signals
LNB Skew Angle
Since linear satellite signals are oriented in a precise cross pattern, the
TracVision antenna’s receiving element, called an LNB (low-noise
block) must be oriented in the same way to optimize reception. This
orientation adjustment is referred to as the LNB’s “skew angle.” The
figure below illustrates how skew determines the amount of signal the
LNB collects. The more signal, the better the reception.

Ideal SkewGood SkewBad Skew
= Satellite Signal = LNB "Signal Collector"
TracVision M3/M2 User’s Guide

Chapter 1 - Introduction
The correct skew setting varies depending on your geographic
location, since the orientation of your antenna to the satellite changes
as you move. For example, as shown in the figure below, if your
antenna is tracking the PAS 9 satellite for Sky Mexico programming,
the ideal skew setting ranges from +30 to +70, depending upon where
you’re located within the satellite’s coverage area.
Figure 4 Approximate Skew Settings for the PAS 9 Satellite
For complete details about adjusting the LNB’s skew, see “Setting the
LNB Skew Angle” on page 31.

Chapter 2 - Operation
Receiving Satellite TV Signals
Television satellites are located in fixed positions above the Earth’s
equator and beam TV signals down to certain regions of the planet
(not worldwide). To receive TV signals from a satellite, you must be
located within that satellite’s unique coverage area.
TIP: For your convenience, KVH provides links to several web sites that offer
satellite coverage information. Simply visit our web site at www.kvh.com/
footprint.
Figure 5 Location of Astra1 Satellite
In addition, since TV satellites are located above the equator, the
TracVision antenna must have a clear view of the sky to receive
satellite TV signals. Anything that stands between the antenna and the
satellite can block the signal, resulting in lost reception. Common
causes of blockage include trees, buildings, and bridges. Heavy rain,
ice, or snow may also temporarily interrupt satellite signals.

Chapter 4 - Setup
7. Loosen the two wing screws securing the LNB to the
choke feed.
Figure 14 LNB Skew Angle Adjustment
8. Adjust the LNB, clockwise or counter-clockwise, until
the skew arrow on the LNB points to the correct skew
angle on the choke feed.
9. Tighten the wing screws.
10. Reinstall the radome.
11. Write down the skew angle somewhere so that you can
easily refer to it in the future.
NOTE: If you wish to learn more about how skew works, see “Linear
Satellite Signals” on page 6.

Make sure the LNB is fully inserted into the choke feed. The
shaft of the LNB must be seated properly against the feed
tube to ensure optimum performance.

Appendix C - Programming User-Defined Satellites
Connecting a Laptop to the Antenna
To program your user-defined satellite(s), you first need to connect a
Windows
®
laptop computer to the TracVision system and start
Windows HyperTerminal.
TIP: If you are a KVH-authorized technician, you can use the KVH Flash
Update Wizard instead of HyperTerminal. Enter commands in the wizard’s
“Antenna Comms” window. You do not need to flash the antenna to enter
commands.
1. Turn off the TracVision antenna.
2. Using a PC serial data cable, connect your laptop to the
DB9 Maintenance port on the back of the interface box.
NOTE: If your computer does not have a DB9 serial COM port, you
can use the USB-to-RS232 adapter manufactured by IOGear
(IOGear part number GUC232A). As an alternative, you can also
use the adapter manufactured by Belkin (Belkin part number F5U109
or F5U409).
