DMX 512 interface

The U.S.Institute of Theatre Technology (hence refered to as USITT) first developed the DMX512 protocol in 1986 as a standard interface between dimmers and consoles. It was a simple concept and was easily adoptable by all concerned. Since the first standard, some improvements was made in 1990 to accomodate some problems and it is now known as the USITT DMX512 (1990) standard.
