Connect Power to the System
NOTE: When powering up a SWM configuration,
apply power to all other system components before
powering up the receivers and DVRs (tuners are
assigned SWM channels during startup).
Follow the steps below to connect power to the
TracVision system (see Figure 26).
a. Before you connect the power wires, turn off
vehicle power and test the circuit to ensure
no power is present.
b. Make sure that the ground wire from the
TV-Hub has been connected to ground as
described on the previous page.
c. Connect the individual power wires to a
dedicated 12 VDC circuit. Connect the
negative (black) wire to ground (DC return)
and connect the positive (red) wire to clean
+12 VDC vehicle power (10-30 VDC is
required at the TV-Hub).
NOTE: If vehicle power fluctuates or is noisy, KVH
recommends that you use the optional 24 VDC
AC-DC power supply (5 A, 120 W) (KVH part no.
72-0669) to provide stable power to the TV-Hub.
d. Reapply vehicle power.
CAUTION
For your own safety, shut down vehicle
power before you connect the power wires.
