If a fixture is assigned a specific address in DMX512, that address determines which:

• A. Channels are controlled by the device
• B. Power supply it uses
• C. Manufacturer
• D. Firmware version

Answer: (A)

In DMX512, each device listens to a specific portion of the 512-channel data stream, starting at a chosen address. The starting address tells the fixture which channels in that stream it should read and respond to. If the fixture uses multiple channels, the address plus the number of channels defines the exact block it controls. For example, a fixture that needs 8 channels set to address 25 will respond to channels 25 through 32. The address does not set or change the power supply, the manufacturer, or the firmware version; those are hardware/firmware details, not part of the DMX channel mapping. This addressing system allows multiple devices to be controlled independently by assigning non-overlapping starting addresses.
