Response to
Query
1 byte Command or Query.
Unit returns the redundancy auto/manual mode of the unit in the form x
where:
0=Manual
1=Automatic
COMMAND EXAMPLE: <0001/ASW=0{CR} (sets Manual switching mode)
7 bytes Query only.
Returns the value of the estimated BER in the form a.bEscc, (representing ab
-c
x 10 ), where:
a.b=BER value
E=exponent indicator
s= sign (+/-)
cc=exponent value.
NOTE: Unit returns 0.0E+00 if the demodulator is unlocked.
EXAMPLE: <0001/BER?{CR}
>0001/BER=4.8E-03{CR}{LF} (returns BER of 4.8 x 10
None Command only.
THIS COMMAND TAKES NO ARGUMENTS.
Forces the unit to clear the stored events log.
EXAMPLE: <0001/CAE={CR}
24 bytes Command or Query.
Sets or returns the user-defined Circuit ID string, which is a fixed length of 24
characters. Valid characters include: Space ( ) * + – , ./ 0 9 and A thru Z
NOTE: Trailing spaces are removed upon entry.
COMMAND EXAMPLE: <0001/CID=ComtechCDM-710L{CR}
1 byte Command only.
Retrieves previously stored configuration from the specified location in the
form x where:
x=0 to 9
EXAMPLE: <0001/CLD=4{CR} (retrieves configuration from location 4)
1 byte Command only.
Stores the current configuration in the specified location in the form x where:
x=0 to 9
EXAMPLE: <0001/CST=4{CR} (stores the current configuration in location 4)
