Fundamentals

DMX Addressing
and Universes

Understand DMX start addresses, channel planning, and the 512-channel universe concept.

Guide Overview

Understanding DMX Addressing and Universes

Addressing tells each compatible device where to read within a DMX data stream. A clear address plan makes fixture groups easier to document, test, and change.

Start addresses

A start address marks the first control channel assigned to a device. Devices that use multiple channels occupy consecutive positions in the same planned channel layout.

Universes

One DMX universe carries up to 512 control channels. Larger systems may use more than one universe, so address records should always identify the relevant universe and start address.

Practical Checks

Record the universe, start address, channel footprint, fixture mode, and physical location for every addressed device.

Planning Notes

Keep an address schedule with the universe, start address, device location, and fixture mode for every assigned device.

Frequently Asked Questions

What is a DMX start address?
