QLab is compatible with any Art-net interface that uses ethernet or WiFi. To connect to DMX-controlled lighting equipment, you’ll need an Art-Net interface, often called a node, which is a device that receives Art-Net messages from a network and outputs DMX messages over a traditional DMX connection. While some lighting instruments and dimmers are able to receive and directly interpret Art-Net messages, most lighting equipment must be controlled using the DMX control protocol. QLab sends Art-Net messages into the network, and those messages are received by other devices on the network which can interpret Art-Net messages. The first is by using the Art-Net protocol, which uses an ethernet or WiFi network to transmit data. QLab 4 communicates with lighting equipment in two ways. Thereafter, and throughout the rest of this documentation, bold text will be used in the traditional manner, as well as to indicate a menu name (such as the File menu.) How QLab Communicates With Lights This is meant to help you notice that you’re being introduced to a new idea. On this page, every time a new tool, interface item, or concept that we feel is particularly essential is mentioned, it will appear in bold text.
