What does DMX stand for?

• A. Digital Multiplex
• B. Data Management Exchange
• C. Direct Message X
• D. Dynamic Matrix Exchange

Answer: (A)

DMX stands for Digital Multiplex, the digital control protocol used to drive stage lighting and effects. The idea behind “multiplex” is that many control channels can be carried on a single data link, so one cable can convey numerous values—each value representing a function like dimming, color, or movement on different fixtures. Being digital means those values are sent as discrete numbers (typically 0–255) rather than analog voltages. In practice, a DMX universe carries up to 512 channels, with each fixture listening to the specific channels assigned to it. The other option phrases don’t reflect the established lighting term.
