Home Schematic Building Protocol Software Ordering Forum LightsOn Links Home of the opto isolated, bus powered, DMX512 interface with both in and out universes. Lixada USB to DMX Interface Adapter LED DMX512 Computer PC Stage Lighting Controller Dimmer. Latest News LightFactory 2.0 ships with support for interface. The interface has the following key features.
DMX lines galvanically opto-isolated from the USB bus. DMX lines over voltage protected, and current limited. Simultaneously send and receive up to 512 channels. I originally designed this interface around the begining of 2004, but due to time pressures, and that fact I work with computers all day long so don't always want to see them in the evening, it actually took me till the begining of 2005 to finish the firmware and polish it to the point where it was ready to be released. 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. I have been interested in lighting for a number of years, but found that the good lighting desks, that can control moving lights, are well beyond the range of my budget as an amateur. 
Being interested in electronics as well I thought about building myself a lighting desk, but soon decided that as a software guy it was going to be a better idea to write one for my G4 powerbook.
