ArtNet

Art-Net

Overview

The Art-Net device enables OnlyView to send and receive DMX512 lighting control data over Ethernet networks using the Art-Net protocol. Art-Net is an industry-standard protocol that allows lighting controllers, dimmers, and other DMX devices to communicate over standard network infrastructure.

Category: Communication Device
Hardware Requirements: Network interface connected to Art-Net network
Software Requirements: None (protocol handled internally)
Compatibility: Art-Net protocol version 3

Setup and Configuration

Network Configuration

Network Interface: Select the network interface that connects to your Art-Net network.

Net and Sub-Net: Art-Net uses a hierarchical addressing scheme: - Net: The top-level network identifier (0-127) - Sub-Net: Sub-network within the Net (0-15) - Combined with Universe (0-15), this creates the full Art-Net address

Emission Settings

Enable Emission: When checked, OnlyView will actively send Art-Net data to the network.

Sending Method: - Prefer unicast: Sends N times the data, once for each listener that registered for this address. Note that you don't have to know the addess of the receiver: using the Art-Net protocol, OnlyView will know who is interested by this addess. - Always broadcast: Sends data to all devices on the network segment. This can flood the network.

Note that above a certain number of registered listeners, OnlyView forcefully uses broadcast.

Sending Frequency: Rate at which Art-Net packets are transmitted when data is changing (1-44 Hz). Higher frequencies provide smoother dimming but increase network traffic.

Idle Frequency: Rate at which Art-Net packets are sent when data is not changing (1-44 Hz). Maintains connection with receiving devices.

Universe Configuration

Configure up to 4 Art-Net universes (ports) simultaneously: - Universe: Local universe number (0-15) - Each universe can carry 512 DMX channels - Universes are combined with Net and Sub-Net to form the complete Art-Net universe address

Reception Configuration

Enable Reception: Allows OnlyView to receive Art-Net data from other controllers on the network.

Monitor Universes: Specify which Art-Net universes to monitor for incoming data.

Actions

Available Actions

Start DMX Record: Begin recording incoming Art-Net data to create cue sequences. - Parameters: None - Usage: Useful for capturing lighting states from other controllers

Stop DMX Record: Stop recording Art-Net data. - Parameters: None - Usage: Ends the current recording session

Send DMX Values: Transmit specific DMX channel values via Art-Net. - Parameters: Universe, Channel, Value - Usage: Send specific lighting commands from timeline cues

Timeline Integration

Art-Net actions can be triggered from Command Cues on any timeline: - Add a Command Cue to a timeline layer - Set the cue's device action to the desired Art-Net action - Configure action parameters as needed - The action will execute when the timeline playhead reaches the cue

The Start/Stop DMX record actions are used to record a lighting console into an .ovdmx file and replay it in place of the console. The full workflow is described on the DMX Recording media page.

User Interface

The Art-Net device widget provides real-time monitoring and control capabilities:

Status Indicators: - Network Status: Shows connection status to the Art-Net network - Transmission Status: Indicates when data is being sent - Reception Status: Shows when Art-Net data is being received

Universe Monitors: Displays real-time channel values for monitored universes with: - Channel numbers (1-512) - Current DMX values (0-255) - Visual level indicators

ActionGraph Nodes

Art-Net Get Channel: Retrieves current value of a specific Art-Net channel - Inputs: Device, Universe, Channel - Outputs: Value (0-255) - Properties: Device selection, universe number, channel number

Art-Net Send Channel: Sends a value to a specific Art-Net channel - Inputs: Device, Universe, Channel, Value - Outputs: None - Properties: Device selection, universe number, channel number

Art-Net Copy Universe: Copies data from one universe to another - Inputs: Source Device, Source Universe, Target Device, Target Universe - Outputs: None - Properties: Source and target device/universe configuration
