What is the control system used to control all aspects of the fixtures, especially the smart lights?

• A. DMX 512
• B. Art-Net
• C. DALI
• D. KNX

Answer: (A)

DMX512 is the standard system used to drive lighting fixtures, including smart lights, by sending channel-based control data. Each fixture listens on a starting address and consumes several channels, with each channel representing a specific attribute (like brightness, color, pan/tilt, pattern). The controller streams a continuous 512-channel frame per universe, allowing a single controller to coordinate many fixtures and their various parameters. This channel-per-attribute setup is exactly what lets you control all aspects of complex fixtures from one system. Art-Net isn’t a control system itself—it’s a way to transport DMX data over Ethernet. DALI and KNX are building or room automation protocols aimed at broader lighting and environment control in buildings, not the specialized, high-speed, multi-parameter control common in stage lighting.
