Garage Door DIP Switch Calculator
Convert legacy garage door opener DIP switch positions into a converted DIP code for compatible universal keypad programming. You can also enter a converted code to reconstruct the physical DIP switch positions.
Click each switch to move it between UP (+) and DOWN (−).
How to Use the Garage Door DIP Switch Calculator
First, identify the garage door opener format. Check the number of DIP switches and whether each switch has two or three positions.
Select the matching format. Then click each visual switch until the calculator matches the physical DIP switch pattern in your opener, receiver, or existing remote.
Click Convert DIP Switch Code. The calculator converts the physical switch positions into the numeric sequence used during compatible universal keypad programming.
You can also work in reverse. Enter a valid converted DIP code and click Convert Code to DIP Switches to display the corresponding physical switch positions.
DIP Switch Code Conversion Table
| DIP Type | Physical Position | Converted Digit |
|---|---|---|
| 2-Position | UP (+) | 1 |
| 2-Position | DOWN (−) | 2 |
| 3-Position | UP (+) | 1 |
| 3-Position | MIDDLE (0) | 2 |
| 3-Position | DOWN (−) | 3 |
Supported Legacy DIP Switch Formats
| Opener ID | Format | Switches | Positions |
|---|---|---|---|
| 21 | Genie 390 MHz | 12 | 2 |
| 22 | Genie 390 MHz | 9 | 2 |
| 23 | Stanley 310 MHz | 10 | 2 |
| 31 | Overhead Door 390 MHz | 9 | 3 |
| 32 | Chamberlain 390 MHz | 9 | 3 |
How Many DIP Switch Patterns Are Possible?
The number of possible patterns depends on the number of physical switches and the number of positions available on each switch.
Possible Patterns = PositionsNumber of Switches
| Configuration | Calculation | Possible Patterns |
|---|---|---|
| 9 Switch / 2 Position | 2⁹ | 512 |
| 10 Switch / 2 Position | 2¹⁰ | 1,024 |
| 12 Switch / 2 Position | 2¹² | 4,096 |
| 9 Switch / 3 Position | 3⁹ | 19,683 |
Example: 9-Switch 3-Position DIP Code
Consider this nine-switch pattern:
+ 0 − + 0 + − 0 +
Using the conversion:
+ = 1 0 = 2 − = 3
the converted DIP code is:
123121321
Is This Calculator Right for Your Garage Door Opener?
Not sure whether your equipment uses physical code switches or a receiver Learn button? First read our Garage Door DIP Switch vs Learn Button Guide to identify the system before converting any code.
This calculator is designed for supported legacy fixed-code garage door systems that use physical DIP or code switches.
If your opener uses a Learn or Program button instead of a row of physical code switches, it may use a different programming system and this DIP switch conversion may not apply.
Check the existing remote, external receiver, or opener documentation to identify the switch count and switch style before selecting a format.
Frequently Asked Questions
What does the Garage Door DIP Switch Calculator do?
It converts supported legacy garage door DIP switch positions into a numeric converted code that may be used during compatible universal keypad programming.
Can I convert a code back into DIP switch positions?
Yes. Select the correct format, enter the converted code, and click Convert Code to DIP Switches.
What does UP mean on a 2-position switch?
In the supported conversion used by this calculator, the UP or + position converts to digit 1.
What does DOWN mean on a 2-position switch?
The DOWN or − position converts to digit 2 for the supported two-position formats.
How are 3-position DIP switches converted?
UP (+) converts to 1, MIDDLE (0) converts to 2, and DOWN (−) converts to 3.
How many patterns can a 10-switch system have?
Ten two-position switches provide 1,024 possible physical switch patterns because 2¹⁰ equals 1,024.
How many patterns can nine 3-position switches create?
Nine three-position switches provide 19,683 possible patterns because 3⁹ equals 19,683.
What is the Opener ID?
The Opener ID identifies the supported legacy garage door opener format during compatible universal keypad programming.
Does this calculator work with rolling-code openers?
No. Rolling-code and many Learn-button openers use a different programming process and do not rely on the fixed DIP switch conversion shown here.
Should I verify the format before programming the keypad?
Yes. Confirm the opener model, switch count, switch type, orientation, and keypad instructions before programming or changing equipment settings.
