C.6.2 Receive (Rx) Commands and Queries
Priority System = RFT (Highest Priority), RMD, RCR, RRS, and RDR (Lowest Priority), as indicated by shading. Any changes to a higher 
priority can override any of the parameters of lower priority.

Response to Query
RX FEC Type
RFT=
1 byte, value 
of 0 through 6 
Command or Query.
RX FEC Type in the form x, where:
0=Reserved 
1=Viterbi 
2=Viterbi + Reed-Solomon 
3=Reserved 
4=Reserved 
5=TCM + Reed-Solomon 
6=Turbo 
Example: RFT=1 (Viterbi only)
RFT= 
RFT? 
RFT* 
RFT# 
RFT$ 
RFT^ 
RFT@ 
RFT?
RFT=x 
(see Description of 
Arguments) 
RX Demod 
Type 
RMD=
1 byte, value 
of 0 through 5 
Command or Query.
RX Demodulator Type in the form x, 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?
RMD=x 
(see Description of 
Arguments) 
RX FEC 
Code Rate 
RCR=
1 byte, value 
of 0 through 7 
Command or Query.
Rx FEC Code Rate in the form x, where:
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) 
7= Reserved 
Depending on FEC and demodulation type, not all of these 
selections will be valid. 
Example: RCR=4 (Rate 3/4)
RCR= 
RCR? 
RCR* 
RCR# 
RCR$ 
RCR^ 
RCR@ 
RCR?
RCR=x
