Description of Arguments
to Query
Command or Query. CDM-570L Only
LNB Power Control, where
0=Off
1=On, 13V LNB Voltage
2=On, 18V LNB Voltage
3=On, 24V LNB Voltage
Example: LPC=1 (LNB power is On, 13 volts)
Command or Query. CDM-570L Only
0=Disable LNB Reference
1=Enable LNB Reference
Example: LFR=0 (LNB 10 MHz reference off)
Command or Query. CDM-570L Only
LNB lower alarm limit for current, in the form xxx, where xxx is
the current value between 10 and 400 mA.
Example: LCL=050
Command or Query. CDM-570L Only
LNB upper alarm limit for current, in the form xxx, where xxx is
is the current value between 50 and 600 mA.
Example: LCH=450
Command or Query. CDM-570L Only
LNB Receive LO frequency information in the form: xxxxxs,
where:
xxxxx is the LO frequency, in the range of 3000 to 65000 MHz
All 0's (000000) disables the feature.
s is the sign for the mix (+ or - character)
Terminal Frequency = LNB LO ± RFQ
Example: LLO=06000- (LO is 6 GHz, high-side mix)
Query only. CDM-570L Only
Indicates the value of the LNB Current, in the form: xxx, where
xxx is between 0 and 999, units mA.
If not available, response is 000.
Example: LDC=210 (LNB DC current is 210 mA)
Query only. CDM-570L Only
Indicates the value of the LNB Voltage, in the form: xx.x, where
xx.x is between 0 and 30.0
If not available, response is 00.0.
Example: LDV=24.2 (LNB DC voltage is 24.2 volts)
