Command Arguments for
Parameter (Instruction
Type Code and
Qualifier)
Tx Modulation TMD= 1 byte,
Type value of 0 thru 5
Tx FEC Code TCR= 1 byte,
Rate value of 0 thru 7
Tx Data Rate TDR= 8 bytes
Front Panel FPL= 1 byte,
Lockout value of 0 or 1

Command or Query.
Tx Modulation type, where:
0=BPSK
1=QPSK
2=OQPSK
3=8PSK
4=16-QAM (Turbo or Viterbi + RS only)
5=8-QAM (Future option)
Depending on FEC type, not all of these selections will be valid.
Example: TMD=2 (which is OQPSK)
Command or Query.
Tx Code Rate, 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 0.95 (Turbo Only)
7 = Rate 1/1 (Uncoded or No FEC)
Depending on FEC and Modulation type, not all of these selections will be valid.
Example: TCR=4 (which is Rate 3/4)
Command or Query.
Tx Data rate, in kbps, between 2.4 kbps and 9.98 Mbps
Resolution=1 bps.
Example: TDR=2047.999 (which is 2047.999 kbps)
Command or Query.
Control the state of front panel lockout, where:
0=no lockout
1=front panel lockout active
Disable the lockout by either FPL=0, or by setting into local mode using LRS=0
(response is LRS+ meaning FPL is disabled at the same time)
Note: When using the Optional IP Module Command Line Interface (CLI), to verify CLI
lockout:
<0/FPL?
>0000/FPL=0 (Lockout disabled) or
>0000/FPL=1 (Lockout enabled)
