BSR E1.11 – 200x, Entertainment Technology–USITT DMX512-A, Asynchronous Serial Digital Data Transmission Standard for Controlling Lighting Equipment and Accessories.

This revision of ANSI E1.11 – 2004, describes a protocol for transmitting digital data used to control entertainment lighting equipment and accessories. Entertainment lighting equipment and accessories includes, but is not limited to, dimmers, robotic luminaires, colour changers, robotic mirrors, dousers, colour wheels, motion effects wheels, and pattern rotators. The revision is being done to correct errors and to clarify text, and to add an Alternate START Code for UTF-8 transmission so that languages other English can be used for sending diagnostic text messages.
