Keypad Scanning 2 of 7 (K version)
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. Switch 1-4 (SW1-4) should be switched to the “off” position.
The reader will then NOT process the keypad data, and it will be decoded by the host in 2 of 7 format.
The keypad has a matrix of contacts corresponding with the matrix of keys. The contact outputs are wired to
the seven terminals of P2. The seven terminals are called P2-1 thru P2-7 and provide the 2 of 7 decode of the
buttons. When a key is pressed, the button closes two contacts that pull 2 lines to ground. This results of the
key entries are in the table below. The reader and the host that is scanning the keypad will require a common
signal ground. The connection is to be made on either pin 2 (power supply ground) or 5 (Data Return) of TB1 of
the ProxPro.
This method of interfacing the keypad requires additional processing by the host. These include the de-bouncing
of the keys, decoding of the keypad, timing between key entries, as well as others depending on the Host. The
2 of 7 format is available on the ProxPro 5355XX
K
XX versions.
