Description of Arguments
Query only.
Unit returns the oldest 5 Stored Events which have not yet been read over the
remote control in the form {CR}Sub-body{CR}Sub-body{CR}Sub-body{CR}Sub-
body{CR}Sub-body, where Sub-body= ABCddmmyyhhmmss is as follows:
A being the fault/clear indicator.
F=Fault
C=Clear
I=Info
B being the fault type where:
1=Unit
2=Rx Traffic
3=Tx Traffic
4=Log
C is Fault Code numbers, as in FLT? or Info Code, which is:
0=Power Off
1=Power On
2=Log Cleared
3=Global Config Change
4=Redundancy Config Change
If there are less than 5 events to be retrieved, the remaining positions are
padded with zeros. If there are no new events, the response is RNE*.
Command or Query.
Rx Pilot On/Off selection in the form x, where:
0=Off,
1=On
Example: RPI=0 (Pilot Off selected)
Note: Valid only in DVB-S2 mode. This is automatically detected on demod
acquisition, but if the unit is not locked, the query returns 'x'.
Query only.
Unit returns the value of the Rx signal level, in dBm, between +3.0 and –99.0
dBm, in the form xxx where;
xxx is the Rx signal level.
Examples: RSL=+03
RSL=-41
Command or Query.
Rx ± acquisition sweep range of demodulator, in kHz, ranging from ± 1 to ± 100
kHz in the form xxx.
Example: RSW=009 (± 9 kHz selected)
