Hi Straight-track,
Welcome to The Gauge!
I am not entirely sure if I know what you are talking about... Is this the turnout controller with 2 buttons for each turnout? Comes in 4, 8, or 16?
If yes, you wire the common (usually black, in Atlas solenoid switch-machine terms) to the centre "rail", and then wire the red to one button, and the green to the matching button. What this board amounts to is a much neater set of momentary contact switches. More compact than the corresponding set of Atlas switches.
