i have an old display like this-the problem is the clock built in to the control panel runs to fast. i want to use an arduino board to control it. but i do not have any tech data to know how the pins are laid out. there is a 9 pin connector that the key pad plugs into. any info would be a great help. also the whole thing runs on a 5 volt power supply that is in working order as far as i know.
