REMOTE CONTROL OPERATION
This appendix describes the remote control operation of the RSU-503 and RSU-503L.
•
Firmware number: FW/3080-1P
•
Software version: 1.14
Notes:
1. Unless indicated otherwise, any references in this appendix to “the switch” apply
to both the RSU-503 and RSU-503L.
2. Before operating the system, ensure the installation is complete and the cable
connectors are tight, especially the connections from the waveguide switch
indicators. If not, no harm will come to the unit, but the online indicators might
read erroneously if the waveguide switch is not set to the same online position as
the coax switches in the switch.
Ambiguity between any of the RF switches can be corrected by commanding a
switchover from A to B, or B to A. This will then latch all switches on the same channel.
This natural ambiguity only occurs during installation, and would only reoccur if a
switch becomes faulty.
Note: The firmware referenced in this manual may be an earlier version of the actual
firmware supplied with the unit.
