Device Configuration Packets
Device configuration packets are used to configure discovered Art-Net devices.
Streaming Control Packets
Streaming control packets are the core of Art-Net and allow real-time channel based control data to be streamed over the network.
RDM Packets
RDM packets are used to discover which RDM devices are connected to which Art-Net nodes and then to control them.
Time-Keeping Packets
Time-keeping packets are used to synchronise Art-Net devices across the network.
Triggering Packets
Triggering packets allow Art-Net devices to trigger macro events in each other.
Diagnostics Packets
Diagnostics packets are used to send diagnostic information over the network to be logged by software such as DMX-Workshop.
File Transfer Packets
File transfer packets are used to upload new firmware to devices and also for the transfer of data files between controllers and nodes.
