Hello,

I have the same model of amplifier, the only problem is that I am a newbie.
I have the USB RS232 cable which is connected to my server ubuntu.

It seems that I missed an argument, but I don't know what. Also there is a file rest.service but I don't know how to use it ?

many thanks for helping me.
