I have replaced an GLK12232-25-WBL with an GLK12232-25-FGW display and have the following problem:
The keycode sent from the display is not the same every keypress. First I tried to increase the debounce time but it has no effect. I have also tried to use different keypads but also with no change in behavior.
I am quite sure I have connected the keypad correctly and I have also tried to simply short two keypad connectors at the time. This is also giving the same result.
When I change back to the GLK12232-25-WBL everything works as before i.e. correct keycode is sent every keypress for all the different keypads and simple short circuit.
The unit I have tested is an Rev3.0(FW) with number 2008081075.
If you press the same key a couple of times what results are you getting back from the display? and what results are you seeing from the old unit when you press that same button?
