Be careful with any of those "Micro-plex, Multi-plex, LMX" dimmers and DMX Controllers. All the manufacturers that make them put +15volts on pin 3 of the XLR connector to phantom power the console. Thats fine when you have a console that outputs that protocol, but if you plug it into a DMX board, it will fry your RS485 Transceiver. I had a client that fried all 4 DMX outputs of a controller that he had. Also, the ND-4600 cannot be upgraded to receive DMX, and a new DMX Dimmer pack would be cheeper than a converter. Just so you all know.
