Description of Arguments
Query
Command or Query.
Rx RS encoding in the form x, where:
0 = RS(225,205,10)
1 = RS(219,201,9)
2 = RS(208,192,8)
3 = RS(194,178,8)
4 = RS(126,112,7)
5 = RS(220,200,10)
Depending on Modem mode, overhead type, and data rate, not all
selections will be valid.
Example: RCW = 0 (This is a 'don't care' if RS is Off under TRS)
Command or Query.
Rx Differential Decoding in the form x, where:
0 = Off
1 = On
Depending on FEC type or Modulation Type, not all selections will be
valid.
Example: RDD = 1 (selects Rx Differential Decoding On)
Command or Query.
Receive Data Fault, where:
0 = None
1 = DATA
2 = AIS
Example: RDF = 0 (selects Data Fault = None)
Command or Query.
Invert Receive Data, where:
0 = Normal
1 = Inverted
Example: RDI = 1 (selects Inverted RX Data)
