Twin IRDs Connection
You can connect two IRDs for your antenna as shown in the following
diagram. One of the IRD’s need to be set up with the ACU in order to use
another IRD without connecting the ACU. Both IRD’s with and without an
ACU connection can receive any channels that are available from the
tracked satellite.
As in the single IRD option, the RF cables from the antenna base plate
should be connected to ‘LNB’, ‘ANT’, or ‘Satellite In’ on the rear panel of
the IRD.
