Response to Query
Rx Eb/No N/A 4 bytes Query only.
Unit returns the value of Eb/No, between 0 to 16 dB.
Format xx.x, resolution 0.1 dB.
Returns 99.9 if demod is unlocked.
R016 for values greater than 16.0 dB.
Example: EBN=12.3 (which is Eb/No = 12.3 dB)
N/A EBN? EBN=xxxx
(see description of
arguments)
Redundancy
State N/A 1 byte, 0 or 1 Query only.
Unit returns the redundancy state of the unit, where
0=Offline
1=Online
Example: RED=1 (which is Online)
N/A RED? RED=x
(see description
of arguments)
Temperature N/A 3 bytes Query only.
Unit returns the value of the internal temperature sensor, in the
form of xxx (degrees C).
Example: TMP=+26
N/A TMP? TMP=xxx
(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 format may be:
No1for1 which indicates that no 1:1 system has been
detected. Presence of a 1kHz signal from the CRS-150
is used to indicate a 1:1 set-up.
NoComm which indicates that a 1kHz signal has been
detected, but that there is no (or not yet) a response
for the modem, or.
abcdef which is the FLT? response information from
the offline 600/L unit.
abcdefghxx which is the FLT? response information from the
offline 625 unit.
N/A OUS? OUS=xxxxxx
