Response Description of Arguments Comments
Interface
Loop-back Command:
Response:
Status:
Response: >add/ILB_xxx'cr''lf']
>add/ILB_xxx'cr''lf']
Where: xxx = On or Off.
Interface Loop
Thru Mode Command:
Response:
Status:
Response: >add/ILM_xxx'cr''lf']
>add/ILM_xxx'cr''lf']
Where: xxx = On or Off.
RTS TX-IF
Control Mode Command:
Response:
Status:
Response: >add/RTSM_xxx'cr''lf']
>add/RTSM_xxx'cr''lf'] Where: xxx = ON or OFF.
This command configures the modem for the RTS
TX-IF control mode. If 'ON' is selected, the TX-IF
output will only be turned on if the incoming RTS
signal is asserted (also the TX-IF output has to be
programmed ON and no major modulator faults
are preset). If 'OFF' is selected, the TX-IF output
will operate normal ignoring the RTS signal.
RTS State
Control Command:
Response:
Status:
Response: >add/RTSS_xxx'cr''lf']
>add/RTSS_xxx'cr''lf'] Where: xxx = ON or OFF.
This command controls the logic of the RTS
signal.
Interface
Firmware
Information Command:
Response:
>add/IFI_xxx'cr'
FW/nnnnn-drr'cr'
mm/dd/yyyy'cr''lf'']
Where:
nnnnn = Firmware number (0 to 65535).
d = firmware dash number (0 to 99).
rr = Firmware revision (-, or A to ZZ).
