S Version - Direct connect keypad Scanning - 3 X 4 Matrix format
The Serial ProxPro reader is available with a 3 x 4 matrix keypad. The keypad is independent of the Serial
ProxPro reader and only provides the connections to the keypad. This mode requires a separate cable to be
supplied that connects to the Keypad board, inside the ProxPro, to the Host via P2. P2 is a 7 position terminal
strip. The following is the table for the contact closures.
This table indicates the connection between the connector pins when a key is pressed. For example, if key 3 is
pressed P2-5 is connected (shorted) to P2-1. This is available on the Serial ProxPro 5352XXSXX versions.
