Need Help with Shure DFR 22 audio mixer RS232 serial command

ajay thomas

Hi,

Can someone help me with a serial command for shure audio mixer.
I was able to get the mute commands to work but have no success with increasing or decreasing the volume

Mute Command
send String dvshure "$D0,'DFR22001INPALLM000',$D1"\\ this code works it mutes all the inputs

Increasing the volume
send string "$D0,'DFR22001INP001L00<100d>',$D1" \\ this does not work,any idea how to transalate <100d>

I have attached shure rs232 command list.

Thanks in advance.

Regards,
Ajay

Try taking out the enclosing '<' and '>'

I got it to work had to convert <100d> to $63

so now the code is

send string"D0,'DFR22INPALL00',$63,$D1" \\ sets volume to 100
