SDM-309B Satellite Modem Remote Control
MN/U-SDM309B Rev. # B-B–5
4.1.4 Set Modulator Power Offset
Command: <add/MPO_snn.n”cr”
Response: >add/MPO_snn.n”cr””lf”]
snn.n = +20.0 to -20.0 in 0.5dB increments.
Note:
This will be the highet modulator power that will be displayed and programmed.
Use the MOP_ command to actually change the modulator output power.
Status Only: <add/MPO_”cr”
Response: >add/MPO_snn.n”cr””lf”]
4.1.5 Set Modulator Output Power Level
Command: <add/MOP_snn.n”cr”
Response: >add/MOP_snn.n”cr””lf”]
snn.n = +20.0 to -45.0 in 0.5dB increments for 140MHz modulator.
snn.n = +20.0 to -30.0 in 0.5dB increments for 70MHz modulator.
Note:
Must be within 25.0dB of the modulator power offset value (see MPO_) for the
140MHz modulator and within 10.0dB of the modulator power offset for the 70MHz
modulator.
Status Only: <add/MOP_”cr”
Response: >add/MOP_snn.n”cr””lf”]
4.1.6 Differential Encoder Enable
Command: <add/DENC_xxx”cr” (xxx = ON or OFF)
Response: >add/DENC_xxx”cr”lf”]
Status Only: <add/DENC_”cr”
Response: >add/DENC_xxx”cr”lf”]
4.2 Demodulator Configuration Commands
4.2.1 Set Demodulator Frequency (to nnn.nnnn MHZ, nnn.nnnn = 50.0000-
90.0000)
Command: <add/DF_nnn.nnnn”cr”
Response: >add/DF_nnn.nnnn”cr””lf”]
Note:
nnn.nnnn = 50.0000 to 90.0000 and 100.0000 to 180.0000 for the 140MHz
demodulator.
