Installing the OPI
To prepare for antenna pointing, attach the OPI to the receive
cable from the LNB, as shown in
Figure 46. Note that 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).
OPI block If you use an OPI with a model J-type radio assembly, you must
use a block (or filter). For details, including the specific block you
should use, see the Hughes Field Service Bulletin (FSB),
Standard OPI Configuration (FSB_060915_01A).
Install the block between the OPI and the radio as illustrated in
Figure 46. If the block you use has two female F connectors (at
both ends), you will have to make a jumper cable to connect to
the OPI.
