The MEM Key is a fully programmable keypad encoder. It can decode key
matrixes of up to 4 columns by 5 rows. The rows and columns can be
programmed to match the row-column configuration of any off the shelf
keypad.

Scan back through the messages...Not too long ago I
posted a reply to a similar question and even posted
source code to scan the keypad using the EDE1144.
