HD-ACU connection (no multiswitch)To connect the HD-ACU:
1. Install the HD-ACU according to the instructions detailed on
page 8.
2. Connect one end of the Power/Data cable to the antenna
baseplate, and one end to the ANTENNA port of the HD-
ACU.
3. Connect a 15 m RF cable from RF1 port on the antenna
baseplate to ANT.RF1 port on the rear panel of the HD-ACU.
4. Connect a 3 m RF cable from RECEIVER port on the rear
panel of the HD-ACU to your Master IRD.
5. Check that the power settings for each of the satellites
(DTV101, DTV119, and DTV110) are set to AUTO - see
“Power settings” below.

capable, e.g. DirecTV H20 Receiver. You will be able to view all
HD programmes on the television set connected to this receiver.
You can also connect a standard IRD to the RF2 port of the
antenna baseplate, but you will not be able to view HD channels.
