numeric Command or Query.
This command allows the user to set the alarm window in
± % of
the calibrated LNA 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=130, set alarm window for LNA A (Aux Comm
1) to
± 30%.
LCW= (message ok)
LCW? (received ok,

found)
LCW* (message ok,
but not permitted in
current mode)
LCW! (command not
accepted by BUC or

value of 1, 2
1=LNA A
2=LNA B
x=1 byte,
Value of 0, 1
0 = Disable
1 = Enable Command or Query.
Allows LNA Fault Logic to contribute to the summary fault relay,
where:
s = Source:
1=LNA A (Aux Comm 1)
2=LNA B (Aux Comm 2)
x = Enable:
0 = Disabled
1 = Enabled
Example: LFL=11
LFL= (message ok)
