Query
(Instruction
Code and
qualifier)
Response to
query
(target to
controller)
Note: If the RS Codec option is not installed, and
the argument 3 or 4 is used, the target will return
RFT? If the Turbo Codec option is not installed,
and the argument 5, 6 or 7 is used, the target will
return RFT? Use EID? to query the options fitted.
Rx FEC
Code Rate
RCR= 1 byte, value of
1,3 or 7
Command or Query.
Rx FEC Code rate, where:
1 = Rate 1/2
3 = Rate 3/4 (must be set for Rate 3/4 Turbo)
7 = Rate 7/8
8 = Rate 21/44 (must set for Rate 21/44 Turbo)*
9 = Rate 5/16 (must set for Rate 5/16 Turbo)*
All other codes invalid.
Example: RCR=1 (which is Rate 1/2)
* Only valid for S/W Version >1.14
As a Query, returns 0 if Uncoded is selected for
FEC
RCR= (message ok)
RCR? (received ok,
but invalid argument found)
RCR* (message ok, but not
permitted in current mode
RCR? RCR=x
(same format as
