DMD2401/DMD2401L/DMD2401 IBS/IDR Satellite Modem
interface card is installed, and the transmit mode
parameter is set to IDR Mode. If an IDR OR IBS interface
card is not installed, set to zero. If an IDR OR IBS
interface card is installed, but the transmit mode
parameter is not set to IDR mode, these bytes can be set
to any valid values, but will be ignored.
-20 to +10, signed binary value in dB
Note: The following two bytes apply only if an IDR OR IBS
interface card is installed, and the transmit mode
parameter is set to IDR Mode. If an IDR OR IBS interface
card is not installed, set to zero. If an IDR OR IBS
interface card is installed, but the transmit mode
parameter is not set to IDR mode, these bytes can be set
to any valid values, but will be ignored.
-20 to +10, signed binary value in dB
Command a Modulator's Frequency
Note: The following command will also turn the carrier off
to protect the satellite.
Unsigned Binary Value in Hz
Command a Modulator's Data Rate
Note: The following command will also turn the carrier off
to protect the satellite.
Unsigned Binary Value in BPS
Command a Modulator's Modulation Type
Note: The following command will also turn the carrier off
to protect the satellite.
0 = QPSK, 1 = BPSK, 2 = 8PSK, 4 = OQPSK
Command a Modulator's Convolutional Encoder
Note: The following command will also turn the carrier off
to protect the satellite.
0 = None
1 = Viterbi 1/2 Rate
3 = Viterbi 3/4 Rate
5 = Viterbi 7/8 Rate
7 = Sequential 1/2 Rate
9 = Sequential 3/4 Rate
11 = Sequential 7/8 Rate
14 = Trellis
20 = TPC 0.7932D
21 = TPC 0.4953D
