Response to
Command
Query
(Instruction &
Qualifier)
Response to Query
Faults and
Status… g= BUC status/faults :
0=OK, masked, or not present
1=BUC current
2=BUC voltage
3 = spare
4=BUC no comms/bad checksum
5=BUC PLL
6=BUC temperature
h= LNB status/faults :
0=OK, masked, or not present
1=LNB current
2=LNB voltage
xx= spares
CnC
Ratio Monitor N/A 4 bytes Query only
When CnC is enabled and the modem is locked, it monitors the
ratio between the interferer and the desired power in dB.
Example 1: CRM==+02 (interferer > desired) (format: =sdd)
Example 2: CRM=LT11 (less than –11 dB)
Example 3: CRM=GT11 (greater than +11 dB)
Example 4: CRM=99.9 (not locked or CnC not enabled)
N/A CRM? CRM=xxxx
(see description of
arguments)
CnC
Delay Monitor N/A 6 bytes Query only.
When CnC is enabled and the modem is locked, it monitors the
delay of the interferer in microseconds.
Example 1: CDM=229500 (229.5 ms)
Example 2: CDM=999999 (not locked or CnC not enabled)
N/A CDM? CDM=xxxxxx
(see description of
arguments)
CnC
Freq Offset
Monitor N/A 6 bytes Query only.
When CnC is enabled, an estimated frequency offset (in kHz)
between desired and interferer will be calculated.
Example 1: CFM=+001.0 (1 kHz)
Example 2: CFM=9999.9 (not locked or CnC not enabled)
N/A CFM? CFM=xxxx.x
(see description of
arguments)
Note – the following codes are used in the ‘Response to Command’ column:
= Message ok # Message ok, but unit is not in
Remote
mode.
? Received ok, but invalid arguments were found ~ Time out of a pass-through message, either to via EDMAC or to a local ODU
* Message ok, but not permitted in current mode
