DMX & Art-Net
ArtNet (Network Sender) ArtNet (Network Receiver) ...and many more
The DMX-protocol transmits up to 512 channels per universe, this is equivalent to a spread of 512 slices.
DMX values are Integers in the range (0..255) but from vvvv you set them in a range of (0..1) instead. Keep in mind that the resolution is still 8-bit though, so only 256 steps (including 0 and 1) are possible.
Art-Net is a standard for transmission of DMX over Ethernet.
vvvv supports the Art-Net II specification with a total number of 256 universes: 16 subnets with 16 universes each.
As defined in the protocol, Art-Net talks over UDP on port 6454 (0x1936). This port number can be changed: just start vvvv from a command line with an option '/artnetport nnnn' (nnnn - your port number).
