Multiple IRDs - DirecTV
This version of a multi-switch uses a multi-switch and a DiSEqC
supplier - Raymarine Part No. A96014 - and enables you to
change the satellite being tracked as you change channels using
the IRD master instead of the ACU.

‘ANTENNA RF1’ of the DiSEqC supplier. (1)
3. Connect an RF cable between ‘RF2’ of the antenna base
plate and ‘LHB RHCP/+13V’ of the multi-switch.
