Arguments for
Command or
Query
45 bytes Query only.
Returns the configuration status of the unit.
EXAMPLES:
<0001/RCS?{CR}
ATT=12.75{CR}
AMP=1{CR}
MUT=1{CR}
ONL=1{CR}
ESW=1{CR}
AOF=00.00{CR}
AFR=1{CR}
XRF=NA{CR}{LF} (SEE NOTE)
Where:
ATT= attenuation in dB
AMP= RF power amplifier state where 0=OFF, 1=ON
MUT=RF mute state where 0=unmuted, 1=muted
RED=Online status for redundancy
ESW=Redundancy and mode states where 0=OFF, 1=ON Tx only, 2=ON Tx & Rx
AOF=Attenuator Offset in dB
AFR= auto fault recovery where 0=manual, 1=auto
XRF=External reference status where NA=no external reference, 05M=5 MHz, and 10M=10 MHz
NOTE: XRF will always be NA if the internal reference oscillator option is not installed.
1 byte Command or Query.
Sets or returns Redundancy Online status in the form x, where:
0=Offline
1=Online
NOTE: this command is functionally identical to the ONL command.
COMMAND EXAMPLE: <0001/RED=1{CR}
3 bytes Command or Query.
Sets or returns the reference oscillator tuning voltage adjustment by sending a DAC value in the form xxx, where:
xxx=is a numeric value from 0 to 255.
Default value: 087
NOTE: This command sets the DAC value, but the actual Reference Oscillator tuning voltage can be monitored
using the RMS command.
COMMAND EXAMPLE: <0001/REF=087{CR}
22 bytes Query only.
Returns the Model Number and the installed M&C firmware version.
EXAMPLE: <0001/RET?{CR}
>0001/RET=CPA-300 VER: 1.0.3{CR}{LF}
