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 2-19.

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 ADCU ground terminal (route the ground
wire to the ADCU 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.
