Thread: Touchscreen Issues

I have a Xenarc 700TSV and a cappachino tx3 computer. I wired it all up, touch screen worked like a champ. It has a program called touchkit i believe that had the touch screen portion of the monitor located at comm 1. Well my engine management system used the serial port for its piggy back system to communicate with. I tried switching the monitor to usb , no dice. I then tried plugging it back to the serial port and now the touch kit says it cant find anything in comm 1. Any suggestions???
