Protocol: DMX-over-Ethernet (sACN/E1.13 and ArtNet)

[DynamoBen]

sACN (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 sACN 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.

Re: DMX-over-Ethernet

ArtNet

It's not directly DMX related but this is one of the open source Ethernet protocols that was used for lighting control. This protocol was used widely prior to the release of the new industry standard ACN (see ACN sticky). The big win here is it isn't very complicated and you don't have to purchase anything (the ACN standard must be purchased from ESTA).
