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.
IMPORTANT: The Master satellite receiver (IRD) must be HD
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.
