the Art-Net II output of a console is identical to Art-Net I – all broadcast. However, with Art-Net II, the console uses a simple algorithm to learn which nodes are consuming which universes. It then switches to unicasting to the nodes. The reduction in network loading achieved with Art-Net II is massive, allowing Art-Net II networks to scale up to the bandwidth of the network. Art-Net II has an effective limit of 256 universes.
