I read something a couple months ago about not being able to have both a keypad and the GPO's work at the same time. Is it true? Could Henry explain it better? I'm planned on building a new pc in late Feb. and don't want to add an LCD unless I can use keypad and GPOs at same time. Thanks in Advance.

Most of our units have GPOs AND Keypads. The LK162-12 and LK402-12 on the other hand share the pins. So with these two models you can have one or the other, while the rest, you can have both.
