1 = Enable (Tri-color LED light)
2 = Test (cycles through colors once
Example:
<0001/LAM=1’cr’
>0001/LAM=1’cr’’lf’
Default Value: 0
LAM= LAM? LAM=x
LNB Current
Source
LCS= 1 byte Command or Query.
This command enables, or disables the LNB current source. Note:
LCS must be enabled before the LNB current can be calibrated.
0 = Disable
1 = Enable
Example: <1/LCS=1’cr’
>0001/LCS=’cr’’lf’
Default Value: 0

LNB Current
Window
LCW= 2 bytes Command or Query.
This command allows the user to set the alarm window in ± % of the
calibrated LNB Current. Valid inputs are 20 to 50 in increments of 1%.
In addition, setting the value to 99
1
disables the alarm function.
*Note: A return value of 99 indicates that the current window is
disabled. This may be because a value of 99 was set for LCW,
or it may be because the CWE has been disabled. Since the
method of setting 99 to this command is being obsoleted, it is
recommended the user utilize CWE instead of 99.
The following example will set the alarm window to ± 30%.
Example: <1/LCW=30’cr’
>0001/LCW=’cr’’lf’
Default Value: 30
LCW=
LCW?
