buffer and the PIN code entry buffer, generates a medium length
beep, and is ready to receive a new card.
The keypad PIN code can be one to five digits long in the range of 0
to 99,999. When entering a keypad PIN code,
#
must be pressed to
signify the end of the PIN entry. When pressing
#
, the data is sent by
the Wiegand data lines. If

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 AY-D19M outputs card data in Wiegand 26-Bit with the
following keypad data:
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 = First key entered
B = Second key entered
C = Third key entered
D = Fourth key entered
E = Fifth 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)
