OpenLCP support for Art-Net

The Art-Net 4 Release 1.4dd2 (1/2/2021) describes three members of an Art-Net network:

• Controller : A lighting console.
• Node : A DMX to / from Art-Net device.
• Media Server : A Media Server.

The ArtPollReply Styles (Table 4) enumerates those, plus an additional 4 device types:

• Route : A network routing device.
• Backup : A backup device.
• Config : A configuration or diagnostic tool
• Visual : A visualizer

The behaviors of Route, Backup, Config, and Visual devices is not specified. The behaviors of Controller, Node, and Media Server are defined, and summarized in a table below.

In OpenLCP, the base class for all Art-Net devices is the ARTNET::Device class. ARTNET::Controller and ARTNET::Node inherit from ARTNET::Device virtually, allowing custom implementations that may need to inherit from ARTNET::Controller and ARTNET::Node to do so with a common base ARTNET::Device.

• ARTNET::Device carries the implementation for:

  • Rx
    • ArtPoll
    • ArtTimeCode
    • ArtCommand
    • ArtTrigger
    • ArtDmx
    • ArtNzs
    • ArtVlc
    • ArtRdm
    • ArtRdmSub
  • Tx
    • ArtPollReply
    • ArtDiagData
    • ArtTimeCode
    • ArtCommand
    • ArtTrigger
    • ArtDmx (Peer to Peer)
    • ArtNzs
    • ArtVlc
    • ArtRdm
    • ArtRdmSub

• ARTNET::Controller extends ARTNET::Device with:

  • Rx
    • ArtPollReply
    • ArtIpProgReply
    • ArtDiagData
    • ArtFirmwareReply
    • ArtTodData
  • Tx
    • ArtPoll
    • ArtIpProg
    • ArtAddress
    • ArtDmx (Controller to Peer)
    • ArtSync
    • ArtInput
    • ArtFirmwareMaster
    • ArtTodRequest
    • ArtTodControl

• ARTNET::Node extends ARTNET::Device with:

  • Rx
    • ArtIpProg
    • ArtAddress
    • ArtSync
    • ArtInput
    • ArtFirmwareMaster
    • ArtTodRequest
    • ArtTodControl
  • Tx
    • ArtIpProgReply
    • ArtFirmwareReply
    • ArtTodData
