Response to Query
Bulk Status
Query N/A 28 bytes Query only.
Note: The CDM-600L requires FW Ver 1.2.0 or higher)
The response is in the form lreeeebbbbbffooooosssssttt, where: N/A
BSQ? BSQ=lreeeebbbbbffooooo
sssssttt
(see Description of
Arguments)
l=local/remote status
r=redundancy state offline/online
eeee=Eb/No
bbbbb=BER
ff= Buffer Fill state
ooooo=Rx Frequency offset
sssss=Rx Signal Level
ttt=Temperature same as LRS
same as RED
same as EBN
same as BER
same as BFS
same as RFO
same as RSL
same as TMP
This command is intended to reduce the need for excessively
frequent queries to the modem, and will be useful for a unit in a
redundancy system, where the redundancy system has monitoring
of its own occurring. The latter 6 parameters are only updated once
per second.
Hardware
Revision N/A 4 bytes Query only.
CDM-600/600L unit returns hardware revision level of both main
circuit boards in the form xxy, where:
xx=the main (bottom) PCB
y=indicates the modem (top) PCB.
FOR CDM-600:
y=0, Units manufactured before February 2005, or
1, Units manufactured after February 2005 (unit provides
extended IF frequency range)
N/A HRV? HRV=xxy
(see Description of
Arguments)
Offline Unit
Status N/A 6 bytes Query only.
(1:1 set-up)
This query is sent to the online modem of a 1:1 pair. It provides
access to the fault status information (FLT?) of the offline modem.
This is the only way to interrogate the status of an offline modem at
the distant-end of a link. The response may be in one of the
following forms:
No1for1: Indicates that no 1:1 system has been detected. The
presence of a 1kHz signal from the CRS-150 is used to indicate
a 1:1 set-up.
NoComm: Indicates that a 1kHz signal has been detected, but
that there is no (or not yet) a response from the modem.
abcdef: Represents the FLT? response information from the
offline unit.
N/A OUS? OUS=xxxxxx
(see Description of
Arguments)
