The AY-Q64 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
F = 8-Bit Facility code
A = 24-bit code generated from keyboard
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
If the PIN code is less than 5 digits, all the most significant nibbles are
filled with 0.
Example:

Where: A =First key entered
B = Second key entered
EP = Even parity for first 12 bits
