Transmit Command:
Response:
Status:
Response: >add/ICFT_xxxx'cr''lf']
>add/ICFT_xxxx'cr''lf']
Where: xxxx = AMI, HDB3, B8ZS, or B3ZS.
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.
