A.2.1 Remote Control Operation
This section describes the remote control operation differences between the standard
firmware for the RFT-500 (FW/3059-2N) and the firmware supported for the CST-5000
Multi-Carrier System (FW/3059-3-).
Note: The firmware referenced in this manual may be an earlier version of the actual
firmware supplied with the unit.
The following additional commands are supported:
External
Fault Uplink Command:
Response:
Status:
Response: >add/XFU_xxx'cr''lf']
>add/XFU_xxx'cr''lf']
Where: xxx = ON or OFF (default = OFF, disable monitor).
Monitors external uplink fault.
External
Fault
Downlink Command:
Response:
Status:
Response: >add/XFD_xxx'cr''lf']
>add/XFD_xxx'cr''lf']
Where: xxx = ON or OFF (default = OFF, disable monitor).

The following command is not supported:
External
Fault
Enable Command:
Response:
Status:
Response: >add/XFE_xxx'cr''lf']
>add/XFE_xxx'cr''lf']
Where: xxx = ON (the default) or OFF.
This command is used to replace the internal HPA fault signal
with a customer-supplied fault signal from an external HPA as
the source of the HPA fault in the 'FS_' command.
The external source interfaces with the RF terminal at
connector J6, pin M. This signal must be an OPEN/GND
signal, with OPEN defined as the fault condition.
