If you are new to the AlphaPix controller, here is the recommended setup method:
Q: When I test the output from my controller using the built-in hardware test and/or my sequencing application, the colors don't come out correct - how do I fix that?
A: While we mostly refer to lights as "RGB" and assume they are always in that order of Red, Green then Blue, the reality is that they are often in different orders. There are two settings that can change the order on your AlphaPix:
Q: Do you have a diagram that helps me better understand the relationship between DMX Channels, DMX Universes and SPI Outputs?
A: Yes, we have a diagram for both the AlphaPix 4 and Alpha 16 that show how DMX Channels and DMX Universes are arranged inside the controller addressing:
AlphaPix 4:
AlphaPix 16:
Q: What do the three status lights on the board mean and/or what do the green and orange status lights on the Ethernet (CAT5) jack mean?
A: There are 5 status lights on the AlphaPix controllers. The following tables list the functions of these lights:
System Board Status Lights (Firmware V1.02+)
Network Jack Status Lights (Instructions are also printed on PCB)
Q: What test modes / built-in sequences are in the controller?
A: The AlphaPix controllers have a variety of test modes which are great for burn-in, finding bad pixels or off-season uses. The following table lists all these modes:
Q: I have a suggestion for an improvement to the firmware (software) or hardware - how can I do that?
A: We love feedback from our customers and you can find current suggestions planned or suggested on our firmware page.
Q: I'd like to purchase spare or replacement plugs used for the pixel outputs for the AlphaPix 16 - where can I find those?
A: If you need additional plugs, they can be purchased at DigiKey.
Q: I'm unable to get output to my pixels and I have verified that the pixels have the right power and the test mode doesn't work.
A: It is not common but in selected cases, when pixels are incorrectly connected or shorted out, the output chip can become damaged. The output chip is in a removable socket in the controller (chips U7 - U10) to allow for it to be replaced in the field. When replacing the chip, note the text on the PCB that says "DIRECTION OF NOTCH/PIN". The chip can be purchased here.
Q: How do I factory re-set my AlphaPix controller?
A: Yes, the firmware can be factory loaded. See the firmware page.
Q: I broke off / shorted / damaged my power input connector, where can I find a replacement?
A: Replacements can be purchased Here. Please note that we do not support the customer repair of controllers.
- Bare Controller - NOT pre-assembled / Ready2Run Kits
- Ensure that AlphaPix controller is on a non-conductive / metal surface. Ideally, we recommend a mounting plate and enclosure
- Connect your power supply to "BANK 1" power input- this should be the same voltage as the pixels connected.
- With the power off, connect your pixels to the SPI output(s).
- Make absolutely sure that no wires are shorted or touching.
- We recommend connecting one string to start.
- Make sure the direction (pixels are all directional) is correct - if you are unsure, check out website product page or your pixel configuration sheet shipped with your HolidayCoro pixels. Arrows should point away from the controller.
- See the following video for wiring instructions:
- Power up controller
- PRE-Assembled / Ready2Run Controllers / Kits
- Plug in pixels to waterproof plug
- Power up controller
- Test the Pixels
- We know you are ready to get going but start by making sure that ALL your pixels work with the controller in hardware test mode first. Do not skip ahead and test or configure the PC sequencing application at this time.
- To test pixels using the built-in hardware test mode, see these videos:
- AlphaPix Evolution:
- At main menu that is scrolling through menu options
- Briefly press M button (S IS PRESSED HERE IN ERROR)
- Display shows "1.SYSTEM SETUP"
- Press S once
- Display shows "DHCP-" and the status of DHCP (YES OR NO). Use + or - to move to the text "DHCP-NO"
- Press S once
- Display shows "STATIC IP" along with the static IP address
- To move between octets (four of them separated by periods) press the OK button
- To change the number in the octet (0 to 255) use the + and - buttons
- Once at the last octet, press OK and the cursor will move back to the first octet
- Press the S button once and this will move to the subnet mask configuration
- Display shows "SUBNET MASK" along with the subnet mast number
- To move between octets (four of them separated by periods) press the OK button
- To change the number in the octet (0 to 255) use the + and - buttons
- Once at the last octet, press OK and the cursor will move back to the first octet
- Press the S button once and this will move to the subnet mask configuration
- Display shows "PIXEL PROTOCOL"
- If you are done with IP address configuration at this time, press the M button to save the settings
- The controller will display "CONFIGURED REBOOTING NOW" and will reboot with the new settings in place
- AlphaPix Classic:
- AlphaPix Evolution:
- Here are the instructions shown above:
- Wait for controller to boot up (usually about 15 seconds)
- Press and HOLD the "M" (1st from left) button until the LCD reads "Entering test mode"
- Press the "+" and "-" buttons (3rd and 4th from left) to cycle through the different output modes
- LCD will display the type of output that should appear on the pixels (Red, Green, Blue, Yellow, White, etc)
- Press and hold the "M" button to exit the test mode, once test mode has been exited, the controller will display "NORMAL MODE"
- Once ALL lights test out correctly and the colors listed on the LCD match those of the actual lights, proceed to the next step. If the lights do NOT light up, check the following:
- Ensure that the lights are hooked up in the right direction.
- Ensure that the lights are the correct voltage for the controller power. If you have 5v pixels, make sure the controller power supply is 5v, etc.
- If most of your outputs work but one or more do not work, see this troubleshooting video:

- Windows 10:
- DO NOT proceed until you are able to PING your controller as shown in the videos above.
- Configure the Pixel Controller Settings Via Web Browser
- This process configures the settings for your specific pixel configuration. As each controller configuration is often unique, the settings are unique to that controller and the pixel type, pixel count and number of pixel controllers in the display.
- We recommend using Google Chrome for best results with your controller. There are known issues with selected versions of Internet Explorer and Safari.
- This video walks through all the standard configuration parameters on the AlphaPix controller:
- Need help understanding how a DMX universe/address is laid out and configured? See our chart at the bottom of this page.
- Test the Output from the PC
- If you are new to E1.31 controllers, we highly recommend starting by testing your pixel output using xLights.
- xLights can be downloaded here: https://xlights.org/releases/
- This video shows the process to setup xLights outputs:

- Setup the E1.31 Application / Sequencing Application
- NOTE: There are hundreds of possible applications on the market today that work with E1.31 and Artnet protocols but the following only shows some of the very common applications used by the holiday lighting community. Due to the rate of change in these applications and the quantity, it is not possible for us to provide specific advice on each application. Please contact your software vendor for assistant on setup of their application to work with our standards based controller.

Q: When I test the output from my controller using the built-in hardware test and/or my sequencing application, the colors don't come out correct - how do I fix that?
A: While we mostly refer to lights as "RGB" and assume they are always in that order of Red, Green then Blue, the reality is that they are often in different orders. There are two settings that can change the order on your AlphaPix:
- "Color Order Output from Application" - This should be set to the color order your application expects the pixels to be in. In nearly all cases this will be "RGB".
- "Pixel Chip Color Order" - This should be set to the color output order of the specific pixels you are using. For example, if you using our #700 pixel strip, the order should be BRG.
Q: Do you have a diagram that helps me better understand the relationship between DMX Channels, DMX Universes and SPI Outputs?
A: Yes, we have a diagram for both the AlphaPix 4 and Alpha 16 that show how DMX Channels and DMX Universes are arranged inside the controller addressing:
