Hello, I recently purchased a Rockwell Collins CDU-900 faceplate off ebay. It has a 37 Pin connector on back and after doing some basic circuit tests the buttons seem to be functioning. I am using it to build a very basic cockpit sim for my boys to play with and the only functionality I'd like to use it for would be for the on/off switch to function and the keypad to backlight. I have two questions:
1. Is the keypad designed to backlight when properly connected and powered on?
2. If so, what would be the proper pin connections and voltage to make this happen? (I already have a pin schematic for the letters, however, I can't find the right combination to light up the keypad, if it is even possible).
I am a beginner at this and learning as I go, any advice would be much appreciated. Thank you,
