Keypad Interface
GTT display keypad has a 12 pin interface, but the manual says KPP4X4 is compatible, but the KPP4X4 has 8 pin interface so how do you connect this keypad?

Re: Keypad Interface
Hello Delshay,
Welcome to the forum!
I understand you are curious about how to interface our 4x4 keypad with the GTT.
Although the Keypad has 8 pins, while the GTT has 12 pins, they will still interface together properly. When connecting the keypad to the display, you will have to place the keypad connector on the middle pins of the keypad header; that is pins 3-10 labelled in the GTT Hardware manual.

Please give this a shot, and let me know if you are still having troubles.
Cheers,
Daniel
