Connecting the ADCU to Vessel Power
Short circuits may result in severe electrical shock or burns. Turn
off vessel power and test the circuit to ensure that no power is
present before connecting any power cables.
The TracVision G6 system requires an 11-16 VDC power input.
Since it does not have a dedicated power control (ON/OFF
switch), a quick-tripping circuit breaker or fuse should be
installed between vessel power and the ADCU. Circuit overload
protection should be rated for 5 amperes. For recommended
power cable specifications, refer to Table 2-2 on page 10.
If vessel power fluctuates widely or is noisy, a 12VDC 5-amp
AC/DC power supply or a wide-range DC/DC converter power
supply should be installed. Test the voltage and polarity before
making connections to vessel power.
Connect power to the green ADCU terminal strip connector as
shown in Figure 2-28. If the user-supplied power cable has a
drain or shielded wire, DO NOT connect the drain or shield to
either the ADCU or to ground.
Connecting the IRD Ground Wire
A grounding wire has been provided to connect your IRD to a
suitable ground. Attach the grounding wire to any suitable screw
on the rear panel of the IRD with a good contact with the IRD
chassis. The other end should be connected to a suitable ground,
ideally to connector 2 of the green ADCU terminal strip
connector (see Figure 2-28). Each IRD connected to the
TracVision system should have a similar IRD ground wire
connection.

Power supplied to the
TracVision G6 MUST NOT exceed
16 VDC or the TracVision power
supply will suffer serious damage!
The ADCU is equipped with a fuse
to protect against high-voltage
spikes. If the system is installed
correctly and power is available, but
the system is non-functional, refer
to Section 4, “Troubleshooting” on
page 91 for instructions on
checking and replacing the fuse.
