Query
Command or Query.
Sets or returns LNB Alarm-to-Rx Alarm attachment, where:
0 = No
1 = Yes
Example: <0/ALA=1 (Attach LNB Alarm to Rx Alarm)
Command or Query.
Sets or returns LNB upper alarm limit for current, in mA, in the form xxx, where:
xxx = current value from 50 to 600
Example: <0/LCH=450
Command or Query.
Sets or returns LNB lower alarm limit for current, in mA, in the form xxx, where:
xxx = current value from 10 to 400
Example: <0/LCL=050
Query only.
Returns the value of the LNB Current, in mA, in the form xxx, where:
xxx = current value from 0 to 999
When unavailable, response is 000.
Example: <0/LDC?
>0/LDC=210 (LNB DC current is 210 mA)
Query only.
Returns the value of LNB Voltage in the form xx.x, where:
xx.x = voltage value from 0 to 30.0
When unavailable, response is 00.0.
Example: <0/LDV?
>0/LDV=24.2 (LNB DC voltage is 24.2 volts)
Command or Query.
Sets or returns LNB Frequency Reference controls in the form x, where:
0 = Disable LNB Reference
1 = Enable LNB Reference
Example: <0/LFR?
>0/LFR=0 (LNB 10 MHz reference off)
