Remote Control Operation
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 present). If 'OFF' is selected,
the TX-IF output will operate normal ignoring the RTS
signal.
Where: xxxx = NRM (Normal Mode), PWR (Turn RF off
on power up), COMM (Turn RF off on power up and loss
of remote communications after 10 seconds), CD (Turn
RF ON when carrier is detected, turn RF OFF when no
carrier is detected. For the RF ON condition, the TX-IF
must be programmed ON. Note: RTS TX-IF, when
enabled over-rides CD).
This command allows for the RF output to be enabled or
disabled depending on the following described conditions.
One application for this command will be in demand
network systems.
Where: xxx = ON or OFF.
Notes:
1. When programmed ON, the MOP (Modulator
Output Power) command is not allowed, only MOP
status is allowed.
2. ASYNC Overhead only.
Where: snn.n = -30.0 to -5.0, in 0.1 steps (nominal range
in dBm).
Notes:
1. The nominal power range is modified relative to
the value specified by the modulator power offset
(MPO_).
2. ASYNC Overhead only.
Where: snn.n = -30.0 to -5.0, in 0.1 steps (nominal range
in dBm).
Notes:
1. The nominal power range is modified relative to
the value specified by the modulator power offset
(MPO_).
2. ASYNC Overhead only.
Where: snn.n = -30.0 to -5.0, in 0.1 steps (nominal range
in dBm).
Notes:
1. The nominal power range is modified relative to
the value specified by the modulator power offset
(MPO_).
2. ASYNC Overhead only.
