Somewhere in me moving things around I managed to mess up the way the keypad connector was when I had first recieved my unit (which pins the plug is on)
I was wondering
a) can someone tell me the correct configuration for this display
b) do I have to reset the display via jumpers, or restart my system, or could I switch the plug while in operation to see if the keypad works again

thanks

keypad will work fine just by pluging it in... of you looking at the back, there should be 3 pins on the left and 1 one the right free when you plug the keypad in.
