Response to
Query
75 bytes Query only.
Returns the oldest 5 Stored Events that have not yet been read over the remote
interface in the form: {CR}Sub-body{CR}Sub-body{CR}Sub-body{CR}Sub-
body{CR}Sub-body, where Sub-body=ABCddmmyyhhmmss:
A=fault/clear indicator where F=Fault, C=Clear, I=Info
B=fault type where 1=Unit, 2=Rx Traffic, 3=Tx Traffic, 4=Log
C=Fault Code numbers, as in FLT? or Info Code where 0=Power Off, 1=Power
On, 2=Log Cleared, 3=Global Config Change, 4=Redundancy Config
Change
ddmmyy=Date in day/month/year format
hhmmss=Time in hours/minutes/seconds format

1) If there are less than 5 events to be retrieved, the remaining positions are
padded with zeros.
2) If there are no new events, the response is RNE*.
1 byte Query only.
Sets or returns the Rx Pilot status in the form x where:
0=Off
1=On

1) Valid in DVB-S2 Mode only.
2) This is automatically detected on demod acquisition, but if the unit is not
locked, the query returns 'x'.
EXAMPLE: <0001/RPI?{CR}
>0000/RPI=0{CR}{LF} (Pilot Off)
3 bytes Query only.
Returns the value of the Rx signal level in the form sxx where:
s=sign (+/-)
xx=Value from -99.0 to +3.0 dBm, in 0.1 dBm steps
EXAMPLE 1: <0001/RSL?{CR}
>0000/RSL=+03{CR}{LF}
EXAMPLE 2: <0001/RSL?{CR}
>0000/RSL=-41{CR}{LF}
