USB DMX

Since its first release in early 2005, I have made a number of improvements to the DMX side of the circuit. These improvements add greater protection to the interface. The DMX lines are now fully galvanically isolated, and have over voltage and protection. They are also protected from excessive current draw. These improvements not only offer better protection to the host computer, but also to the interface. Since the revision 1.2 improvements I have now redesigned the PCB around a specific high quality case, which was I think one of the main elements lacking with this interface... How to build (cheaply) a fully opto isolated, bus powered, DMX512 interface with both in and out universes.
