Command
Query
(Instruction
Code and
Qualifier)
Response to Query
Faults and
Status (cont) c = Rx Traffic status:
0=Rx Traffic OK
1=Demodulator unlocked
2=AGC Alarm - signal out of range
3=Demux Lock (Frame SYNC)
4=Spare
5=Buffer Slip
6=AIS detected on incoming data
7=Eb/No alarm
8=Buffer Clock activity
9=LNB current (CDM-600L)
A=LNB voltage (CDM-600L)
d = Open Network:
0=No Faults
1=Loss of Tx frame
2=BER Alarm
3=Loss of Tx multiframe
4=Tx signaling AIS
5=Tx Remote alarm
6=IBS satellite alarm
7=IDR Rx BWA1
8=IDR Rx BWA2
9=IDR Rx BWA3
A=IDR Rx BWA4
B=IDR Tx BWA1
C=IDR Tx BWA2
D=IDR Tx BWA3
E=IDR Tx BWA4
e = Change in fault status since last poll
f = Change in unit configuration since last poll
Rx BER N/A 5 bytes Query only.
Units returns the value of the estimated corrected BER in the form
a.b x 10
-c . First three bytes are the value. Last two bytes are the
exponent. Returns 99999 if the demodulator is unlocked or BER
data is unavailable.
Example: BER=4.8E3 (BER=4.8 x 10 -3 )
N/A BER? BER=a.bEc
(see Description of
Arguments)
Buffer Fill
State N/A 2 bytes Query only.
Unit returns the value of the buffer fill state, between 1 and 99%.
Returns 00 if demodulator is unlocked.
Example: BFS=33 (33%)
N/A BFS? BFS=xx
(see Description
of Arguments)
