The XSAT allows the user to select whether or not the summary fault relay is activated if
the LNA current moves out the prescribed window. This allows the user to control
whether or not the redundancy controller will switch on a LNA current alarm in the
redundant configuration. (The factory default is 0)

The Operating mode of the Comtech EF Data Redundant Switch Unit (RSU-5060) can be
set via a command to the ONLINE XSAT. The RSU-5060 initializes to the AUTO mode
when power is first applied.
•
In AUTO mode the RSU-5060 monitors the state of the two XSATs and will
automatically switch the OFFLINE unit online if the ONLINE unit faults.
•
In MANUAL mode, the RSU-5060 will only switch the position of the Tx and Rx
transfer switches when commanded to do so via either the RTG= command or via
Pin V on the ‘M&C Control’ connector (J5) on the RSU-5060. The user sets
AUTO mode by sending a ‘1’ in the data field and MANUAL mode with a ‘0’ in
the data field.

The User can cause the RSU-5060 Redundant Switch Unit to switch the position of both
the Tx and Rx transfer switches using this command.
•
If the RSU-5060 is in AUTO mode, the command will only cause a switchover if
the OFFLINE unit is currently UNFAULTED.
•
If the RSU-5060 is in MANUAL mode, the command will cause a switchover
independent of the state of the OFFLINE unit.
