ComNav Vector G2 & G2B Installation & Operation Appendices

DRAFT #3 – 29 May 2009
Cable Usage
• For the 15 metre cable supplied on the first-generation G2s (marking 051-0063-003),
there are several black coloured signal wires, each carrying a different signal – which
can be very confusing.
To help prevent wiring errors caused by “many black wires”, all the wires in this cable
are twisted in pairs, with each black wire paired with its respective non-black coloured
counterpart. Each pair is also held together by a short piece of tubing, just after they
exit from the cable’s overall jacket.
Caution! If you must cut type 051-0063-003, be sure to maintain the
signal wire pairings.
• For all the other cable types, the second colour listed in the table below is either
repeated bands of the colour, or a thin spiralling stripe of that colour. The wires are
twisted in pairs (but without any pair-retaining tubing).
Caution! The coloured “stripe” is either repeated bands of the colour, or
a thin spiralling stripe. The stripe can be very hard to see (especially
the Blue, Green & Brown stripes, all on Black backgrounds); please
inspect the wires carefully, under a good light, to be sure you are
using the right wires!
Note: the Installation chapter’s Colour Code information (Table 2, and
Figure
12, Figure 14 & Figure 15) shows only the colour codes of the
cable types currently supplied with the Vector (cable type numbers
051-0157-002 & 051-0158-0001 – see the 3
rd
column in Table 26
above).
For the earlie
r cable types, listed in the 1
st
& 2
nd
columns of Table 26,
please use the colours in either the 1
st
or 2
nd
column (whichever
applies) that match the signals you are using, instead of the colours
shown in the Installation chapter.
• All cables can potentially be used on all generations of the Vector G2.
Note: because there are differences – with respect to the output data
signals – between the first and subsequent generations of the Vector,
the signals available on the cable depend on both the cable type and
the Vector’s generation.
L If the older cable types are used with third-generation Vector G2 &
G2Bs, the Alarm output is not provided; because of this, such use
may not be approved by some Standards organizations!
