RX Demod
Type
RMD= 1 byte, value
of 0 through 5
Command or Query
RX Demodulator, where:
0=BPSK
1=QPSK
2=Reserved
3=8-PSK
4=16-QAM (Turbo or Viterbi + Reed-Solomon)
5=Reserved
Depending on FEC type, not all of these selections
will be valid. All other codes are invalid.
Example: RMD=1 (QPSK)
RMD=

RMD*
RMD#
RMD$
RMD^
RMD@
RMD? RMD=x
(see description
of arguments)
RX FEC Code
Rate
RCR= 1 byte, value
of 0 through 7
Command or Query
0=Rate 5/16 (Turbo Only)
1=Rate 21/44 (Turbo Only)
2=Rate 1/2
3=Rate 2/3 (8-Psk TCM or 8-QAM only)
4=Rate 3/4
5=Rate 7/8
6= Rate 17/18 (Turbo Only)
