Don't do the auto configure. What that does is scans the attached hardware looking for a usb dongle and assigns that to the LOR network. Getting rid of your LOR network is half the battle when changing to dmx.
Hi Lennon
I missed this message from earlier as I was working and then just had a quick glance back in chat and didn't see it. I am assuming that 1-5 and 11-20 actually means that channels 1-15 (connectors 1-5) and 31-60 (connectors 11-20) are working. There are 4 fuses with each fuse covering 15 channels. It sounds like the fuse protecting channels 16 to 30 is blown. If it is blown it may have just been a dicky connector. If it is blown like it sounds like then the leads on that channel should be checked with a multimeter. There's other ways of checking the channels/leads but they're complicated to explain.
