ANSI E1.20 - 2010
Remote Device Management
Over DMX512 Networks
ANSI E1.20 - 2010, Entertainment Technology-RDM-Remote Device Management over USITT DMX512 Networks, describes a method of bi-directional communications over a USITT DMX512/1990 or ANSI E1.11 - 2004 data link between an entertainment lighting controller and one or more remotely controlled lighting devices. The protocol was written to work with the ANSI E1.11-2004 control standard, but will work equally well with the current 2009 version of E1.11. 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.
The 2010 edition corrects errors in the 2006 edition, and adds a new message to say that a previously reported problem has been cleared. The 2010 edition is bookmarked for easier use.
