If you are talking about using it for a mass start race you would set it up with a jumper from the finish of one course to the start of the other. I usually run the race clock on the left course and the gap time on the right course. In this case jump C4 (left finish) to C0 (right start). This will give the start impulse for your gap to the finish impulse of the race. Start the race clock on the left course when the race starts. When the first racer finishes push a button connected to the jumper and stop the left course and this will, at the same time, start the right course. Your left course display will freeze with the winning time for the race and your second display will start counting up with the gap time. If you want the gap time to freeze for finishers you can use one of the intermediate channels for the right course to stop the gap time and then resume to count up after the set delay. As far as bibs go I usually use a common pair like 1 for race and 11 for gap and do this for each wave of racers (if there are more than one start wave). You really dont have to use more than two bib numbers for this situation so auto loading of bibs is not required. The display will show information for whatever bib is loaded in the start/finish for each course.
