Arguments
for Command
(Note that all arguments are ASCII numeric codes from 48 to 57)
or Query
1 byte Command or Query.
Sets or returns the Rx RS encoding in the form x, where:
0 = Interleaver Depth 4
1 = Interleaver Depth 8
2 = Interleaver Depth 16
Note: Depending on the active modem mode, overhead type, and
data rate, not all selections will be valid.
Example: <0001/RRD=0{CR} (This is a 'don't care' if RS is Off under
RRS)
1 byte Command or Query.
Sets or returns the Rx RS encoding in the form x, where:
0 = Off
1 = On
Note: Depending on the active modem mode, not all selections will
be valid.
Example: <0001/RRS=0{CR} (sets RS encoding as Off)
5 bytes Command or Query.
Sets or returns the Tx Spreading Equation in the form abbbb, where:
a = 0 (for Equation 0) or 1 (for Equation 1)
bbbb = GSN (Gold Sequence Number) 0000-9999
(for Equation 0) OR GSN 0000-4095 (for Equation 1)
Example 1: <0001/RSE=05000{CR} (Rx Equation 0, GSN 5000)
Example 2: <0001/RSE=14095{CR} (Rx Equation 1, GSN 4095)
3 bytes Command or Query.
Sets or returns the Rx Spreading Factor in the form xxx, where:
xxx = value from 001 to 512.
Note: Values other than 1 are only valid when Modem Type = LDPC.
Example: <0001/RSF=001{CR} (sets Rx Spreading as OFF)
