What is Streaming-ACN (E1.31)?
ACN is a suite of protocols (via Ethernet) that is the industry standard for lighting and control. ESTA, the creator of the standard, ratified a subset of this protocol for "lightweight" devices which is called DMX-over-ACN or E1.31. This lightweight version allows microcontroller based lighting equipment to communicate via ethernet, without all the overhead of the full ACN protocol. In an effort push early adoption ETC provided the protocol information (code and draft specification) at no charge.
Protocol Description
E1.31 is ethernet based and is sent via UDP. The two accepted transport methods are multicast and unicast, the most common implementation is multicast. When using multicast all the controller needs to do is subscribe to the multicast address for the universe that you want to receive data from.
