The free Digital Enlightenment USB-DMX Interface is a professional, high performance DMX Interface for self-construction. It features fully DMX512-compliant simultaneous input and output, as well as the possibility to merge the input universe with the pc-output directly in the interface. Another feature is the possibility to exactly tune the dmx-timing parameters for maximum performance and compatibility with devices that don't fulfill the dmx512-specification. You can also use the interface as a DMX-repeater in standalone-mode by connecting a 9-12V power supply.
The dmx-values of the input and output universe are stored in an internal buffer to minimize USB and CPU-utilization, so your CPU is free for running the lighting software. USB-communication is highly optimized for maximum performance. The interface features direct USB-communication and does not use slow RS232-emulation chips. You can connect up to 32 USB-DMX interfaces to one PC.
The Digital Enlightenment USB-DMX Interface is compatible to a great number of PC-lighting software
