artnet-base

Art-Net is a protocol to send DMX512 data over Ethernet/UDP. This package provides functionality to construct such Art-Net packages and to send them to Art-Net nodes.

var options: ArtnetSenderConfig = {
    host: '2.0.0.5',
    networkInterface: 'eth0',
}

const artnet = new ArtnetSender( options );
artnet.send( 0, [255, 0, 0, 220, 240, 63 ] );

artnet-base provides classes for different Art-Net packages to make crafting an own package easy. Currently, ArtnetDmxPackage is available.

About Art-Net

Art-Net can be used to send DMX data to Art-Net nodes (i.e. a device which receives Art-Net packages over TCP/IP and then converts them to DMX). It also provides a lot of additional functionality, as described in the Art-Net 4 Specification. A selection of Art-Net packages:

• ArtPoll to query information about the device status, name, and IOs
• ArtTimeCode to send timecodes for syncing audio and video
• ArtCommand and ArtTrigger to send application specific commands and triggers
• ArtDmx and ArtNzs to send DMX data; the latter is used to send DMX data starting at a channel > 1
• ArtFirmwareMaster to update device firmware

Art-Net nodes by default use an IP address in the 2.x.x.x/8 range.

About artnet-base

This package was written to control a LED Rail (the Stairville LED Pixel Rail 40 RGB MKII) over Ethernet from a Raspberry Pi. It was inspired by the artnet package, but I needed a reliable and fast version.
