DMX Overview

When it comes to DMX, LightAct can send or receive both Art-Net and sACN protocols. Both protocols are used to transmit lighting control data over Ethernet networks, allowing for seamless communication between LightAct and other lighting devices.

DMX Network Settings

To setup the DMX, navigate to Edit -> Project Settings and open the DMX Tab.

In this window, you first have to select one of the available Network interface controllers (NICs). In most cases, you should avoid choosing 127.0.0.1 (localhost).

If you are in the process of receiving DMX data, sending DMX data, or scanning Art-Net nodes, you will not be able to change the NIC for DMX data.

In the Art-Net section, you can determine the transmission type which will be used with Art-Net protocol:

• Unicast (recommended): this is one-to-one transmission, so it is the most efficient.

• Broadcast: in this transmission type, the messages are broadcast all over the network.

In the sACN section, you can determine the transmission type which will be used with sACN protocol:

• Unicast: one-to-one transmission.

• Multicast (recommended): one-to-many transmission that is very efficient.

• Broadcast: one-to-many transmission.

Broadcast transmission type should be, if possible, avoided as it can slow down the network.
