AYC-Qx4 family manual Page 25
After a card is presented to AYC-Qx4, the program LED starts to
flash in Green and indicates that AYC-Qx4 is waiting for the PIN
code. If the entry of one to five digit keypad PIN code is disturbed
and no digit key or # key is pressed within 5 seconds, the keypad
will clear the card buffer and the PIN code entry buffer, generate
a medium length beep and be 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, 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 will clear the card buffer and the PIN code
entry buffer, generate a medium length beep and is ready to
receive a new card.
AYC-QX4 output card data in 26-Bit Wiegand with the following
keypad data in 26-Bit Wiegand 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 B 12 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.
