Status
Faults Command:
Response: >add/BCSF_abcdefghijklmnop'cr''lf']
This command causes all mod 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. Additional fault status of new options
and features will be appended to the end or use
existing reserved bits.
Character 'a': Modulator fault status character 1.
Bit 6 = 1 always.
Bit 5 = Modulator module 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.
Character 'b': Modulator fault status character 2.
Bit 6 = 1 always.
Bit 5 = IF Synthesizer.
Bit 4 = Data Clock Synthesizer.
Bit 3 = I Channel.
Bit 2 = Q Channel.
Bit 1 = AGC Level.
Bit 0 = Configuration.
Character 'c': Modulator fault status character 3.
Bit 6 = 1 always.
Bit 5 = IF module.
Bit 4 through Bit 0 reserved.
