In DMX512, what does the address specify?

• A. The instrument's function and channels
• B. The power supply
• C. The color temperature
• D. The unit price

Answer: (A)

DMX512 uses a starting point in the 512-channel data frame to control devices. The address specifies where a fixture’s data begins, which channels are allocated to that fixture’s controls. Since each fixture uses a fixed number of channels for its functions (like dimming, color, movement, etc.), the address tells the fixture which portion of the data stream it should listen to. This mapping of channels to a device’s control parameters is what defines its function in the setup. The address does not set power supply, color temperature, or price, which are separate from how the control data is arranged in the DMX stream.
