Response to
Query
2 bytes Command or Query.
Sets or returns the CDI-60 HSSI Invert Rx Data in the form sx where:
s=1 (Interface Slot 1 only)
x=Invert Rx Data where 0=Normal, 1=Inverted
NOTE: Not valid for Slot 1 CDI-40 ASI or Slot 2 CDI-70 GBEI operation.
10 bytes Query only.
Returns the Composite Rx Data rate, in the form xxxxxx.xxx where:
xxxxxx.xxx=rate in kbps, in 1 bps steps.
EXAMPLE: <0001/RDR?{CR}
>0000/RDR=002047.999 (Reports 2047.999 kbps data rate)
1 byte Command or Query.
Sets or returns the redundancy state of the unit in the form x where:
0=Offline
1=Online
NOTES:
1) The unit cannot be forced online. You can force the unit offline by
sending RED=0.This is only valid if redundancy mode is enabled. If
redundancy is not enabled, then RED=0 returns an error.
2) The unit is always online if Redundancy Mode is not selected.
COMMAND EXAMPLE: <0001/RED=0{CR} (force unit offline)
0 bytes Command only.
THIS COMMAND TAKES NO ARGUMENTS.
Restores the unit to factory default configuration.
EXAMPLE: <0001/RFD={CR}
5 bytes Query only.
Returns the value of the measured frequency offset of the carrier being
demodulated in the form sxxx.x where:
s=sign (+/-)
xxx.x=value in range from ± 0 to 100 kHz, in 100 Hz steps
NOTE: Returns 999999 if the demodulator is unlocked.
EXAMPLE: <0001/RFO?{CR}
>0001/RFO=+002.3{CR}{LF} (reports +2.3 kHz offset)
