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.
