DMX DIP Switch Calculator
Enter a DMX start address from 1 to 511 to see which DIP switches should be ON. You can also click the visual switches manually to calculate the DMX address.
Click any visual DIP switch below to toggle it ON or OFF.
How to Use the DMX DIP Switch Calculator
Enter the DMX start address required by your fixture and click Calculate. The calculator will show the matching DIP switch positions.
You can also use the tool in reverse. Click the visual switches to match the configuration on a physical fixture, and the corresponding DMX address will update automatically.
DMX DIP Switch Address Values
Add the values of all switches that are ON to calculate the fixture’s DMX start address.
| Switch | Value | Power of 2 | Binary Position |
|---|---|---|---|
| SW1 | 1 | 2⁰ | LSB |
| SW2 | 2 | 2¹ | Bit 1 |
| SW3 | 4 | 2² | Bit 2 |
| SW4 | 8 | 2³ | Bit 3 |
| SW5 | 16 | 2⁴ | Bit 4 |
| SW6 | 32 | 2⁵ | Bit 5 |
| SW7 | 64 | 2⁶ | Bit 6 |
| SW8 | 128 | 2⁷ | Bit 7 |
| SW9 | 256 | 2⁸ | MSB |
Example: DMX Address 173
Suppose your fixture needs DMX start address 173.
128 + 32 + 8 + 4 + 1 = 173
The switches that should be ON are:
SW8 + SW6 + SW4 + SW3 + SW1
The corresponding 9-bit binary value is: 010101101.
DMX DIP Switch Address Range
Nine binary address switches can represent values from 0 through 511.
DMX start addresses normally begin at 1, so this calculator uses a practical address range of 1 through 511.
When all nine switches are ON:
1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 = 511
Why Can’t Nine DIP Switches Set Address 512?
A nine-bit binary switch bank has a maximum value of 511. Address 512 would require another binary bit with a value of 512.
Some DMX equipment supports higher addressing through a digital display, menu system, software configuration, or a different switch arrangement.
If your fixture supports address 512, follow its manufacturer instructions rather than assuming the 10th switch is an address bit.
Frequently Asked Questions
What is a DMX DIP switch address?
It is a DMX start address configured with physical switches on a lighting fixture or other DMX device. Each switch represents a binary value.
How do I calculate a DMX DIP switch address?
Add the values of every switch that is ON. Common DMX addressing values are 1, 2, 4, 8, 16, 32, 64, 128, and 256.
What switches are ON for DMX address 173?
Address 173 equals 128 + 32 + 8 + 4 + 1, so SW8, SW6, SW4, SW3, and SW1 are ON with the layout used by this calculator.
What is the highest address with nine DIP switches?
The maximum value is 511 when all nine binary address switches are ON.
Why does DMX use binary DIP switches?
Binary switches provide a simple hardware method for setting an address without requiring a display or software menu.
What does Switch 1 represent?
In the common LSB-first layout used by this calculator, Switch 1 represents a value of 1.
What does Switch 9 represent?
Switch 9 represents a value of 256 in the binary arrangement used by this calculator.
What does Switch 10 do on a DMX fixture?
Its purpose varies by fixture. It may control another mode or function rather than addressing. Check the fixture documentation before changing it.
Can I use the calculator in reverse?
Yes. Click the visual switches to match the physical configuration on your fixture. The calculator will display the resulting DMX address.
Should I check the fixture manual?
Yes. Switch numbering, ON direction, addressing limits, and special switch functions can vary between fixture manufacturers and models.
