Multiple Multiswitch Installation
If you need to connect more than four IRDs to the TracVision
antenna, you may carry out a multiple multiswitch installation,
as shown in Figure 2-11.

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 DC
ground, ideally to the switchplate's ground terminal (route the
ground wire through the switchplate panel cutout and leave
unconnected for now). Each IRD that you connect to the
TracVision system should have a similar ground connection.
If you are using a multiswitch, you can ground the multiswitch instead
of the individual IRDs.
