We have an access control keypad at the storage site that looks like this. It's an old DigiGate/PTI keypad:
It works by letting people enter their code (as digits) followed by an asterisk (*). Unfortunately though, some keypads also do the same but require a pound (#) at the end, which makes it very confusing for customers.
So I was thinking to wire those two keys together, * and #, so that they had the same function.
I opened it up and saw that there's this 10-pin connector that goes to the keyboard (unplugged on this pic):
So two questions:
1. What would be the interface that they are using the transmit keystrokes?
and
2. Is it possible to use something like a Pi board, or similar, to do what I want here?
