Circuit
Identification
CID= 80 bytes Command or Query.
CID is a user-defined string of data that may be used to identify or
name the unit or station. The CID is an 80-byte field of data that is
entered as one line, but it will be read back from the unit as two 40-
byte lines of data.
Examples:
<1/CID= Station #001--SSPA #01--’cr’
>0001/CID=
<1/CID?’cr’
>0001/CID=’cr’
Station #001--SSPA #01--’cr’’lf’
Default Value:
--------------CUSTOMER ID---------------

Calibrate LNB
Current
CLC= N/A Command or Query.
The CLC command stores the value of the LNB Current Supply (in
mA) as a reference point. The LNB current alarm point is then
determined by the calibrated LNB reference point, and the LNB
current window setting (see LCW command).
Note: this command will return a mode error if the LNB current source
output has not been enabled first (see LCS command).
Example: <1/CLC=’cr’
>0001/CLC=’cr’’lf’
The CLC query will return the value that was stored during the
LNB current calibration.
Example: <1/CLC?’cr’
>0001/CLC=xxx.x
Where:
xxx.x is the calibrated LNB current value in mA.
Default Value: 000.0
CLC=

CLC? CLC=xxx.x
