I finally got to the point that I want to install these signals and realized that I don't have any information as to making connections to the board. I didn't take a pic of the signals themselves.
I'm not sure which are the emitters and which are the collectors and I don't know why I have 3 of 1 type and 2 of the other.
More importantly; does anyone have the instruction sheet for making connections to the board?
Thank You
