The following two sections have been added to explain how to connect
multiple IRDs and TVs to the TracVision SA.
Installing Two IRDs and TVs
To connect a second TV and IRD to the TracVision SA system,
you must connect a second RF cable to the RF2 connector within
the Antenna Unit baseplate. The other end of the RF cable should
be run down into the vehicle and connected directly to the
second IRD. The data cable remains connected to the first
(master) IRD. Each IRD/TV pair can operate independently of
the other, allowing different viewers to watch different channels.
However, the master IRD must remain turned on if the second
IRD is in use.
Connecting Three or More IRDs and TVs
To install three or more IRD/TV pairs, an active multiswitch
(Channel Master model 6214IFD or equivalent) is placed between
the Antenna Unit and the IRDs. Figure 2-24 illustrates typical
wiring arrangements for multiple IRDs. If more than four IRDs
are required, contact KVH for additional wiring instructions.
Mount the multiswitch unit in accordance with the
manufacturer’s instruction sheet.

A Guide to TracVision SA – ADDENDUM
54-0149 Addendum to Rev. D
KVH recommends the use of
RG-6 or RG-11 (75 ohms) cable
for RF wiring. Use of non-RG-6
or RG-11 (75 ohms) cables will
result in degraded performance.
The KVH warranty does not cover
degraded performance due to
improper wiring.

Using an Active Multiswitch
The data cable should be attached
to the master IRD. The master IRD
must remain on for the secondary
IRDs to function properly.
