ACN (American National Standard ANSI E1.17-2006) was developed by the Technical Standards Program of Entertainment Services and Technology Association (ESTA). For more information please refer to ESTA's Control Protocols Working Group.
Engineering Arts have been major technical contributors andsupporters of the ACN project since very early in its development.
Since ANSI approval, a number of extensions have been proposed to the ACN standard and it is expected that an official Errata clarifying some issues and correcting mistakes is expected to be available for public review soon. It is advisable for anyone interested in adopting or implementing ACN to contact the Technical Standards Manager at ESTA for current status. ESTA creates open standards in a process which is open to participation from any interested party.
A project to write an open source implementation of the main ACN protocols is well under way. For more information visit www.openacn.org or go to the project page at sourceforge.net.
Draft documents have been withdrawn from this page at ESTA's request – contact Engineering Arts for further information. With an ongoing revision project, new drafts are expected soon. Meanwhile the full and official text is available as always from ESTA or from ANSI.
