I've recently bought an "Excellent Condition" Demux 48, off a well know auction site. Unfortunately the unit was not as described in the listing and when used it became evident that it was faulty. When switched on the unit goes through the normal config procedure, and indicates DMX Address 001. After a variable amount of time, the readout goes nuts, Address values increasing and decreasing, then flickering on and off. If it is attached to dimmer all outputs seem to be 100%. It does not respond to DMX. Any help on this would be appreceiated.
