History

Developed by the Engineering Commission of United States Institute for Theatre Technology (USITT), the DMX512 standard (For "Digital Multiplex with 512 pieces of information) was created in 1986, with subsequent revisions in 1990 leading to USITT DMX512/1990.

DMX512-A

In 1998 the Entertainment Services and Technology Association (ESTA) began a revision process to develop the standard as an ANSI standard. The resulting revised standard, known officially as "Entertainment Technology—USITT DMX512-A—Asynchronous Serial Digital Data Transmission Standard for Controlling Lighting Equipment and Accessories", was approved by the American National Standards Institute (ANSI) in November 2004. It was revised again in 2008, and is the current standard known as "E1.11 – 2008, USITT DMX512-A", or just "DMX512-A".

In January 2011 ESTA merged with PLASA, a similar organization in the UK. The new organization is called Plasa.All ESTA standards are now maintained by Plasa.
