Response to
Query
4 bytes Query only.
Returns the value of Es/No in the form xx.x where:
xx.x=Value from 0 to 22 dB, in 0.1 dB steps.
NOTES:
1) Valid in DVB-S2 Mode only.
2) Returns 99.9 if demod is unlocked.
3) For values greater than 22.0 dB, the reply will be ESN=+022
EXAMPLE: <0001/ESN=?{CR}
>0000/ESN=12.3{CR}{LF} (Es/No reports as 12.3 dB)
1 byte Command or Query.
Sets or returns redundancy mode in the form x where :
0=Disable
1=Enable
COMMAND EXAMPLE: <0001/ESW=1{CR} (enables redundancy mode)
4 bytes Query only.
