2.4.1 Connecting the Antenna Data Cable
to the IRD
TracVision SA will not function properly unless you connect the
data cable, the procedures for which vary based on your selected
satellite TV service. The end of the data cable fitted with two DB9
connectors remains within the vehicle. This will be hooked up to
the IRD as discussed later. For your reference, the pin
assignments for the data cable DB9 connectors are detailed in
Appendix C . The other end of the data cable will be attached to
the TracVision SA as described in the following section.
TracVision SA Data Cable Wiring Process
1. Feed the cable up to the roof and through the third
liquid-tight fitting (#3) from the left as pictured in
Figure 2-14.
2. Refer to Figure 2-16 for the proper arrangement of
data cable wires within the terminal strip.
3. After connecting the data cable to the
TracVision SA, hook up the other end to the IRD
as described in the next subsections.
DIRECTV
The data cable for TracVision SA is equipped with a male
DB9 (low-speed data port) connector. Connect the DB9 connector
on the data cable to the low-speed data port on the back of the
IRD.
Wiring to an IRD with a DB15 Connector
Should the IRD only be equipped with a DB15 connector, follow
the alternate wiring directions provided in
Appendix C .
This port is static-sensitive, so
observe the proper precautions.
Before starting, make certain that
the IRD is not plugged into an
AC outlet.

Proper Terminal Strip Wiring
Arrangement – Data Cable
All IRDs are susceptible to AC
power fluctuations that can result in
the IRD locking up and requiring a
reset. Refer to
Section 4.2, “IRD
Troubleshooting,” for a solution to
this issue.
