I'm not quite sure, whether it's the original cable, since I bought 
everything in used condition. It has a female rectangular plug with 10 
pins for the Vario and an RS-232 9 pin for the PC on the other end.

If You have the pin layout, I could check, if it's correct, and 
eventually solder it myself correctly. If this would be the solution, 
I'll be very happy!

You mean the connection ports? There are two and both have same

I'll be happy to get it running through a regular RS-232 port on a 
commodity PC. I've bought the USB connector, because the seller claimed, 
that it would work with that.

Yes, the adapter is connected as / dev / ttyUSB0 and configured so. Yet, 
same symptoms. No reaction.

I'd be really happy about the pin layout of the original serial connector.

Thanks so much,
