You connect to power driver board (5V but you can also connect to a 12V source to ensure enough power is fed to the display which will convert to 5V). I installed mine a few months back, and I connected to J117 (Pin 2 +12V = red wire & Pin 3 Ground = black wire).

FYI, here is what my PIN2DMD looks like from back.

I connected mine as was suggested to me by the manufacturer. Just to clarify, I connected red to the 12V pin, not the 5V. My board has been nothing but perfection since I received it. I had it for months outside of my pin testing with a dedicated power supply, and now installed in the pin the way I illustrated for several months. Not saying that others don't have a negative experience, but mine has been purely positive.

Also, if you board is newer, it may be of different design. If that is the case, then my instruction may not apply.

Still working on colorization. I run mine in re about 50% brightness right now.

Okay guys, here is what you need to know about the connections & buttons on the back of the DMD board:

- When plugging into PC use micro-usb to communicate with pin2dmd software
- For power when installed on pin, I've been informed for the German Gaming Systems version to use a 12V power supply connected to the 12V leads coming from the back of the DMD assembly to power the system (just like it was connected to the pinball machine). Do not plug a 12V adaptor directly into the board as I believe this may only be a 5V connector.
- Can do the same as above plus connect DMD ribbon cable to pinball machine when testing prior to permanent installation
- To manually adjust settings on board (e.g. single color and brightness) you can do the following:
1) Power board on
2) While holding the blue user button down, press and release the black reset button (continue holding down blue button) DMD will reset then you will see "CONFIG MENU" displayed on bottom of DMD. You may now release the blue button
3) Push Menu button to cycle through menu options
a) Device Mode
b) Color Palette
c) Brightness
d) Enhancer (I don't know what this does)
e) Save Config
f) Exit
4) While on a given menu, press the option button to cycle through the options. When you arrive to the option you want, press the menu button to accept that option
5) To save your settings, press menu button until you see Save Config then press option button (you will see "saved" and the DMD will reboot)
