the card buffer and the PIN code entry buffer, generates a medium
length beep, and be ready to receive a new card.
The keypad PIN code can be one to five digits in length in the range
of 0 to 99,999. When entering a keypad PIN code, the # key must be
pressed to signify the end of the PIN entry. When pressing the # key
press, the data is sent by the Wiegand data lines. If the * key is
pressed, the keypad clears the card buffer and the PIN code entry
buffer, generates a medium length beep, and is ready to receive a
new card.
The AYC-Ex5/AYC-T65 output card data comes in Wiegand 26-Bit
with the following keypad data in Wiegand 26-Bit format:
 Card Data: (EP) AAAA AAAA AAAA BBBB BBBB BBBB (OP)
Where:
 EP = Even parity for first 12 A bits
 OP = Odd parity for last 12 B bits
 PIN Data: (EP) 0000 AAAA BBBB CCCC DDDD EEEE (OP)
Where:
A = The first key entered D = Fourth key entered
B = Second key entered E = Fifth key entered
C = Third key entered
EP = Even parity for first 12 bits OP = Odd parity for last 12 bits
If the PIN code is less than 5 digits, all the most significant nibbles are
filled with 0.
Example: (EP) 0000 0000 0000 0000 AAAA BBBB (OP)
Where:
A = The first key entered B = Second key entered
EP = Even parity for first 12 bits OP = Odd parity for last 12 bits
