Query only.
Returns the redundancy state of the unit in the form x, where:
0 = Offline
1 = Online
Example: <0/RED?
>0/RED=1 (selects Online)
Query only.
Returns the unit internal temperature, in degrees C, in the form sxx, where:
s = sign (+ or –)
xx = value
Example: <0/TMP?
>0/TMP=+26
Query only. (1:1 set-up)
Sent to the online modem of a 1:1 pair. Returns the fault status information (FLT?)
of the offline modem in the form abcdef, where:
abcdef = The FLT? response information from the offline unit
Note: This is the only way to interrogate the status of an offline modem at the
distant-end of a link.
Query only.
Returns the value of SNR of the remote demod in the form xx.x, where:
99.9=Demod is unlocked.
xx.x=Not in ACM.
EXAMPLE: <0/RSN?
>0/RSN=12.4
Query only.
Returns the value of Local Signal Noise Ratio in the form xx.x, where:
99.9=demod is unlocked.
EXAMPLE: <0/SNR?
>0/SNR=12.3 (indicates SNR @12.3 dB)
