Installing the OPI
To install the OPI, you need:
•
The OPI, Hughes P/N 1031393-0002
•
A 22 kHz filter, P/N 1500950-0001.
•
Two short jumper cables
To use the OPI for Ku-band antenna pointing, you must use the
filter specified above.
For the jumper cables, use the same cable type as the IFL cables
with male F connectors. Use short jumpers to keep the OPI close
to the antenna so it can be easily read during pointing.
Install the OPI as follows:
1. Make sure the IDU is powered ON.
2. Make sure the transmit cable is connected between the radio
transmitter (IFL connector) and the IDU (SAT OUT
connector).
3. Disconnect the receive cable from the LNB on the radio.
4. Use the jumper cables to connect the OPI and filter inline
between the IDU and LNB, exactly as shown in Figure 46.
Important: The OPI will not work unless it is enabled on the
appropriate screen on the installation software. (Check the box
labeled
Enable OPI Display .) For further details, see Outdoor
Pointing Interface Operating Instructions (1031832-0001).
