Command or Query.
This command allows the user to set the alarm window in
±
% of the calibrated LNA/LNB bias Current. Valid inputs are
20 to 50 in increments of 1%. In addition, setting the value
to 99 disables the alarm function.
Default is disabled.
Example: LCW=230, set alarm window for the LNB bias tee
to
± 30%.
LCW= (message ok)
LCW? (received ok, but

LCW* (message ok, but

LCW! (command not
accepted by BUC or

2=LNB bias tee
x=1 byte,

0 = Disable
1 = Enable
Command or Query.
Allows LNA/LNB Fault Logic to contribute to the summary
fault relay as follows:
Source Enable
1=LNA A (Aux Comm 1)
0 = Disabled
2=LNB bias tee 1 = Enabled
Example: LFL=21 would generate a fault if the measured
current for the bias tee varied from the calibrated operating
point stored by the CLC=2 command more the % allowed
by the LCW=2xx command
LFL= (message ok)
LFL? (received ok, but
