KVH Industries TracVision G4 - Manual (Page 33)

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 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.
