Arguments for
Command or
Query
2 bytes Command or Query.
Sets or returns the alarm window in ±% of the calibrated LNB Current in the form xx, where:
xx=20 to 50, in increments of 1(%); set to 99 to disable (SEE NOTE).
Default value: 30
NOTE: A query return value of 99 indicates that the current window is disabled. This method is due to become
obsolete. Comtech recommends that you use the CWE command/query instead of specifying 99 here.
COMMAND EXAMPLE: <0001/LCW=30{CR} (sets the alarm window to ±30%)
145 bytes Query only.
Returns the five oldest stored events in the alarm log, in the reply format:
YYYYYYYYYY ZZ mmddyy hhmmss{CR}
YYYYYYYYYY ZZ mmddyy hhmmss{CR}
YYYYYYYYYY ZZ mmddyy hhmmss{CR}
YYYYYYYYYY ZZ mmddyy hhmmss{CR}
YYYYYYYYYY ZZ mmddyy hhmmss{CR}{LF}
Where:
YYYYYYYYYY is the fault description.
ZZ is the event type FT=Fault; OK=Clear; or IF=Information
mmddyy hhmmss=date / time stamp.
NOTE: If there are no events in the log the unit will reply with LNA*. All events that are read from the log are also
automatically removed from the log.
EXAMPLE: <0001/LNA?{CR}
>0001/LNA={CR}

FAN #1 OK 175504 052307{CR}

5 bytes Command or Query.
Sets or returns the threshold for the low forward power alarm/fault in the form xx.xx:
Default value: 00.00
NOTES:
1) If the forward power drops below the specified value, the alarm/fault will be indicated.
2) Setting this parameter to 00.00 effectively disables the threshold.
COMMAND EXAMPLE: <0001/LPT=00.00{CR}
