Just to make this clear for everyone interested in this. The Projector offers DMX connection via XLR connectors and cables. This is helpfull to integrate all the functionality to an already existing light controlling desk.
But beside that, the projector offers ArtNet over the usual ethernet connection, which should exist in most cases anyway for easier configuration.
This is as well the case for others brands 'bigger' projectors, like epson or panasonic. But most of them do not offer the classic DMX via XLR.
