Hey guys, I got my hands on an adapter for a closed dmx to usb adapter. How is this going to effect what software I can run the show with? Ok let me edit this. First as is probably already apparent, I don't have a ton of knowledge about DMX. Someone is loaning me their dongle but says that it can only be used on a closed dmx. The one he currently uses is open and for his open dmx. Can someone explain why the dmx being closed or open effect what software I use?
