Hendrik,

As I understand it, you are able to discover the device successfully and GET/SET the DMX Address, but can't get the DEVICE_INFO message.

First thing I would do is put a scope on the line and see if the device appears to be responding at all. It could be that the timing window for receiving the message is off.

If you aren't seeing any response on the wire at all, then I would look at the data you're sending in the GET:DEVICE_INFO message, make sure that all the fields have valid data and the checksum is correct. It's easy for something like that to cause the responder to trash your request as being invalid...
