RF Mode
Control

Command:
Response:

Status:
Response:

>add/RFMD_xxxx'cr''lf']

>add/RFMD_xxxx'cr''lf']

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.

Description

AUPC Local
Enable

Command:
Response:

Status:
Response:

>add/LPC_xxx'cr''lf']

>add/LPC_xxx'cr''lf']

Where: xxx = ON or OFF.

Note: When programmed ON, the MOP (Modulator Output

Power) command is not allowed, only MOP status is
allowed.

AUPC
Nominal
Power Level

Command:
Response:

Status:
Response:

>add/NOMP_snn.n'cr''lf']

>add/NOMP_snn.n'cr''lf']

Where: snn.n = -30.0 to -5.0, in 0.1 steps (nominal range in dBm).

Note: The nominal power range is modified relative to the

value specified by the modulator power offset (MPO_).

AUPC
Maximum
Power Limit

Command:
Response:

Status:
Response:

>add/MAXP_snn.n'cr''lf']

>add/MAXP_snn.n'cr''lf']

Where: snn.n = -30.0 to -5.0, in 0.1 steps (nominal range in dBm).

Note: The nominal power range is modified relative to the

value specified by the modulator power offset (MPO_).

AUPC
Minimum
Power Limit

Command:
Response:

Status:
Response:

>add/MINP_snn.n'cr''lf']

>add/MINP_snn.n'cr''lf']

Where: snn.n = -30.0 to -5.0, in 0.1 steps (nominal range in dBm).

Note: The nominal power range is modified relative to the

value specified by the modulator power offset (MPO_).

AUPC Eb/No
Target Set
Point

Command:
Response:

Status:
Response:

>add/ENSP_nn.n'cr''lf']

>add/ENSP_nn.n'cr''lf']

Where: nn.n = 3.2 to 16.0, in 0.1 increments (Eb/No in dB).

AUPC
Maximum
Tracking
Rate

Command:
Response:

Status:
Response:

>add/MAXT_n.n'cr''lf']

>add/MAXT_n.n'cr''lf']

Where: n.n = 0.5 to 6.0, in 0.5 increments (max tracking rate in
dBm/minute).

AUPC Local
Carrier Loss
Action

Command:
Response:

Status:
Response:

>add/LCL_xxxx'cr''lf']

>add/LCL_xxxx'cr''lf']

Where: xxxx = HOLD, NOM, or MAX (power level setting when
local carrier loss).
