Unit returns the current fault and status codes for the Unit
(hardware), Tx Traffic, and Rx Traffic, in the form abcdef, where:
a = Unit faults:
0=No faults
1=Power supply fault, +5 volts
2=Power supply fault , +12 volts
3=Power supply fault, –5 volts
4=Power supply fault, +18 volts
5=Power supply fault, –12 volts
6=Spare
7=Tx synthesizer lock
8=Rx synthesizer
9=Power cal Checksum error
A=FPGA main chain load fail
B=Turbo FPGA load fail
C=Modem (top) card FPGA load fail
D=MUX FPGA load fail
E=Demux FPGA load fail
F=Rx synthesizer2 (CDM-600L)
F=(Hi-stability module) No PLL Lock (Suppresses Tx) (CDM-600)
b = Tx Traffic status:
0=Tx traffic OK
1=No clock from terrestrial interface
2=Tx FIFO slip
3=AIS detected on incoming data
4=AUPC upper limit reached
5=Ref PLL (CDM-600L)
5=(Hi-Stab module) Ref Activity fault (CDM-600)
6=BUC current
7=BUC voltage
8=BUC no comms or bad checksum
9=BUC PLL
A=BUC temperature
N/A FLT?
FLT=abcdef
