Pines 1, 6, 8, and 9 will be are data pins (CD, DSR, CTS, and RI.) hook the red and green wires up to these 4 however you wish because it can all be sorted out in software.

Nice! The software we used only monitors one data line per lane, so Steve came up with the idea of using two mirrors to accomplish that same thing. you will have the laser pointer at the starting line, cross the lane to a mirror that will take the beam along the lane to another mirror that will take the beam cross the lane along the finish line to the detector. I tried this setup and it was VERY easy to setup and use. You break the beam when you are over the start line and this will trigger the counter, then you'll break the same beam on the finish line stopping the counter.
Good luck!
