/*
 * ANSI E1.20-2006, Entertainment Technology
 * Remote Device Management over USITT DMX512, describes a method of
 * bi-directional communications over a USITT DMX512/1990 data link
 * between an entertainment lighting controller and one or more
 * remotely controlled lighting devices. The protocol also is intended
 * to work with the ANSI E1.11-2004 control protocol. It allows
 * discovery of devices on a DMX512/E1.11 network and the remote
 * setting of DMX starting addresses, as well as status and fault
 * reporting back to the control console.
