Description of arguments
(Note that all arguments are ASCII numeric codes between 48 and 57)
Command or Query.
Allows the user to set the alarm window in ∀% of the calibrated LNA Current. Valid inputs are 20
to 50 in increments of 1%.
Default Value: 30
Example: To set the alarm window to ∀30%:
<1/LCW=30'cr'
>0001/LCW='cr''lf'
Command or Query.
Allows the user to set the threshold for the low forward power alarm/fault in dBm. If the forward
power drops below the specified value (while the unit is online, unmuted and PLL locked), the
alarm/fault will be indicated. Setting this parameter to -20.0 effectively disables the threshold.
Valid values for this parameter are between the unit's specified P1dB power level, and P1dB
minus 19dB. For example, for a unit with +12dBm at P1dB, the range would be +12.0 to -7.0
dBm.
Default Value: -20.0
Example: <2/LPT=+10.0'cr'
>0002/LPT='cr''lf'
Note: This command can only be queried for the offline unit in the redundancy mode.
Command or Query.
Mutes the unit, where:
0 = Disabled (Not Muted)
1 = Enabled (Muted)
Default Value: 0
Example: <2/MUT=1'cr'
>0002/MUT=1'cr''lf'
Note: Mute State cannot be changed for the offline unit when in redundancy mode.
Query only.
Returns the Comtech EF Data part number of the unit. This part number is the unit's DOTCODE
at the time it was manufactured. The DOTCODE may be up to 96 printable ASCII characters
long.
Example: <2/PNM?'cr'
>0002/PNM=BUCC0.350WRSW00'cr''lf'
Command or Query.
Forces the unit to throw the switches, causing the unit to go offline (if it is currently online). The
unit cannot be forced online, and sending a 1 will have no effect.
0 = Offline
1 = Online (query only)
Default value: 0
Example: <2/RED=0'cr'
>0002/RED='cr''lf'
