B.2.8.19 Bulk Consolidated Status Faults
This command causes all modem fault status to be returned. To reduce the length of the
response, fault status is embedded into the bit structure of the characters that are returned.
Faults are indicated by a binary 1 in the designated bit position.
Command:
Response: >add/BCSF_abcdefghij”cr””lf”]
Where: Character “a”: Modulator fault status character 1.
Bit 6 = 1 always.
Bit 5 = Modulator fault.
Bit 4 = RF output status, actual not programmed status (1 = ON, 0 = OFF).
Bit 3 through Bit 0 = Binary representation (0 to 10) of the number of modulator stored
faults.
Where: Character “b”: Modulator fault status character 2.
Bit 6 = 1 always.
Bit 5 = AGC fault.
Bit 4 = Modulator RF synthesizer fault.
Bit 3 = Bit clock fault.
Bit 2 = Transmit clock fault.
Bit 1 = I channel fault.
Bit 0 = Q channel fault.
Where: Character “c”: Demodulator fault status character 1.
Bit 6 = 1 always.
Bit 5 = Demodulator fault.
Bit 4 = Carrier detect status (0 for decoder lock).
Bit 3 through Bit 0 = Binary representation (0 to 10) of the number of demodulator
stored faults.
Where: Character “d”: Demodulator fault status character 2.
Bit 6 = 1 always.
Bit 5 = Demodulator RF synthesizer fault.
Bit 4 = not used.
Bit 3 = I channel fault.
Bit 2 = Q channel fault.
Bit 1 = Bit clock fault.
Bit 0 = BER threshold fault.
Where: Character “e”: Common equipment fault status character 1.
Bit 6 = 1 always.
Bit 5 = M&C fault.
Bit 4 = Interface fault.
Bit 3 through Bit 0 = Binary representation (0 to 10) of the number of common
equipment stored faults.
