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.
