Connect Power to the System
NOTE: Apply power to all other system components
before powering up the receivers and DVRs (tuners are
assigned SWM channels during startup).
Follow these steps to connect power to the
TracVision system, but do not power it on.
a. Make sure the TV-Hub’s ground wire has been
connected as described on the previous page.
b. Connect the TV-Hub power cable (supplied in
kit) to the 10-30 VDC power input on the rear of
the TV-Hub.
c. Connect the black wire of the TV-Hub power
cable to DC return (ship’s ground), and the red
wire to the vessel’s DC power supply (see
Figure 36).
d. Connect the SWM power inserter’s power cable
to an AC power supply.
NOTE: The TV-Hub requires 10-30 VDC from an
appropriate DC power source. An optional 24 VDC
AC-DC power supply (5 A, 120 W) is available from
KVH (part no. 72-0669). The SWM power inserter
requires 120 VAC. DC-AC power inverters are available
from third party suppliers, if required.
e. Check for proper grounding by using a
multimeter to measure the AC and DC voltages
between the ground stud on the rear of the TV-
Hub and ship’s ground. The measured voltage
should be less than 2 VAC and 2 VDC.
f. Repeat step e with the TV-Hub powered on,
looking for the same measured result (see “Turn
On the System” on page 23).
WARNING
If you measure 2 volts or greater, notify the
ship’s electrician or authorized vessel
representative immediately. This is a
dangerous condition. Do not touch the TV-
Hub rear panel or connect anything to it until
the problem is fixed.
