Connecting the Antenna Data/Power Cable
Connect the antenna data/power cable to the data/power
connector on the MCU’s rear panel (see
Figure 2-16 ). Do not
overtighten; finger-tight is sufficient.
Connecting Vessel Power and the IRD Ground Wire
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. Do NOT reapply
power until all system wiring is completed.
The TracVision G8 system requires an 9-36 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 MCU. Circuit overload
protection should be rated for 30 amperes. For recommended
power cable specifications, refer to
Table 2-2 on page 22 .
A power connector plug has been supplied in the kitpack to
make connecting power to the MCU a snap. To connect the
power and IRD ground wires, follow the simple steps below.
1. A large ferrite coil is supplied in the kitpack to
help reduce conducted emissions from the vessel
power cable. This ferrite coil needs to be installed
for the system to comply with CE standards. To
install the ferrite coil, make two loops in the vessel
power cable and clamp the ferrite coil around the
loops (see Figure 2-17). The cable, with both
positive and negative wires, must pass through the
ferrite coil three times to be effective.

TracVision G8 Owner’s Manual - Guide to Technical Information
KVH recommends a 24 VDC power
input to the TracVision G8
(supplying not less than 9 VDC at
the MCU). Power supplied to the
TracVision G8 MUST NOT exceed
36 VDC or the TracVision power
supply will suffer serious damage!
Before connecting the power cable,
turn off vessel power and test the
circuit to ensure that no power is
present.
