How to Find the DMX Address on a Light

Every DMX fixture needs a start address to work correctly.
If the address is wrong or overlaps with another fixture, lights will behave unpredictably.

This guide explains how to find and set the DMX address on common lighting fixtures, using both DIP switches and digital displays.

What is a DMX address?

A DMX address tells a fixture where to start reading data from the DMX universe.

It is:

• a number between 1 and 512

• set directly on the fixture

• independent of the controller

The address does not describe what the fixture does — only where it listens.

Two common ways DMX addresses are set

Most fixtures use one of these methods:

1. DIP switches

2. Digital display with buttons

The method depends on the fixture’s age and complexity.

Method 1: DIP switches

Older and simpler fixtures often use DIP switches on the back or bottom of the unit.

Each switch represents a value:

• Switch 1 = 1

• Switch 2 = 2

• Switch 3 = 4

• Switch 4 = 8

• Switch 5 = 16

• Switch 6 = 32

• Switch 7 = 64

• Switch 8 = 128

• Switch 9 = 256

To set an address, you add the values of the switches that are turned on.

Example:

To set address 13:

• Turn on switches 1, 3, and 4

• 1 + 4 + 8 = 13

This method works, but is easy to misconfigure if switches are bumped or misread.

Method 2: Digital display and buttons

Most modern fixtures use:

• a small LED or LCD display

• buttons labeled Menu, Up, Down, Enter

To set the DMX address:

1. Power on the fixture

2. Press Menu until you see an address value (often labeled

   A001

   )

3. Use Up / Down to select the address

4. Press Enter to confirm

The display usually shows:

• the start address

• the channel mode

• other configuration options

Address vs channel mode (important distinction)

The DMX address and channel mode are separate settings.

• Address = where the fixture listens

• Mode = how many channels it uses

Changing the channel mode:

• changes how many channels the fixture consumes

• does not automatically change the address

• can cause channel overlap if not planned

This is one of the most common causes of DMX issues.

How to verify the address is correct

After setting the address:

• check the fixture’s display or DIP switches

• confirm the controller is outputting DMX

• raise a channel that should control the fixture

• verify that only the intended fixture responds

If multiple fixtures react:

• addresses are overlapping

• or fixtures are in the same mode unintentionally

Common addressing mistakes

• Two fixtures sharing the same start address unintentionally

• Forgetting to change the address after changing mode

• Assuming the controller sets the address (it does not)

• Misreading DIP switch values

• Setting an address too high for the selected channel mode

Practical tips

• Write addresses down during setup

• Label fixtures if they move often

• Set addresses in consistent increments

• Double-check addresses before troubleshooting anything else

Addressing problems are far more common than cable or controller failures.

Summary

• Every DMX fixture requires a start address

• The address tells the fixture where to read data

• Addresses are set on the fixture, not the controller

• DIP switches and digital displays are the two common methods

• Incorrect addressing causes unpredictable behavior
