Keypad Programming Instructions
AY-T6350 Installation and Programming Manual 21
5.4.7 Single Key, 3x4 Matrix Keypad (MD-P64)
Each key press immediately sends 4 bits data, no parity bits added.
0 = 0000 6 = 0110
1 = 0001 7 = 0111
2 = 0010 8 = 1000
3 = 0011 9 = 1001
4 = 0100 * = 1010 = "A" in Hexadecimal
5 = 0101 # = 1011 = "B" in Hexadecimal
5.4.8 1 to 8 Keys BCD, Clock & Data
This option buffers up to 8 keys and outputs keypad data, much like
standard Clock and Data card output.
The keypad PIN code can be one to eight digits in length. The PIN
code length is selected while programming the reader for Option 8.
The reader transmits the data when it receives the last key press of
the PIN code. The data is sent across the two data output lines as
binary data in Clock & Data format.
If * or # is pressed during PIN code entry, the keypad clears the PIN
code entry buffer, generates a beep, and is ready to receive a new
keypad PIN code.
If the entry of the digit keypad PIN code is disrupted and a number
key or # is not pressed within 5 seconds, the keypad clears the PIN
code entry buffer, generates a medium length beep and is ready to
receive a new keypad PIN code.
