The Accu-Lites PM42 Breakout Board is set up to accept up to two inputs and four distinct outputs. Each output can be configured with jumpers to make it a reversing section. The board comes with one set of jumpers that allows you to set that particular section to reversing, assuming the correct OpSwitches have been set inside the PM42s memory.
