Brett.. As I see it on the parts overlay and the schematic, Rob has provided a cure to the problem I was having with the output pulse from the timer board.. If you select to put a wire in the circle marked (P) at resistor R4, you have a positive pulse, which was what I needed to hook my design powerboard to his timerboard. Of course if you select that spot for positive pulse, you eliminate R5 from the circuit and vice-versa..if you select R5, eliminate R4 for a negative pulse, which is the way the timer board was originally designed..
Am I right Rob???
