fifth key press of the 5-digit PIN code, the data is sent across the
Wiegand Data lines as binary data in the same format as a 26-bit
card.
If * is pressed during PIN code entry or a PIN code greater than
65,535 is entered, the keypad clears the PIN code entry buffer,
generates a beep and is ready to receive a new 4-digit keypad PIN
code.
If the entry of the 1- to 5-digit keypad PIN code is disrupted and no
number key is pressed within 5 seconds, the keypad clears the PIN
code entry buffer, generates a medium length beep and is ready to
receive a new 1- to 5-digit keypad PIN code.
(EP) FFFF FFFF AAAA AAAA AAAA AAAA (OP)
Where: EP = Even parity for first 12 bits
OP = Odd parity for last 12 bits
F = 8-Bit Facility code
A = 24-Bit code generated from keyboard
5.4.6 6 Keys BCD and Parity Bits, Wiegand 26-Bit
This option sends a buffer of 6 keys, adds parity, and sends a 26-bit
BCD message. Each key is a four bit equivalent of the decimal
number.
The keypad PIN code must be 6 key presses long. On the sixth key
press of the 6-digit PIN code, (# and * keys are valid), the data is sent
across the Wiegand Data lines as a BCD message.
If the entry of the 6-digit keypad PIN code is disrupted and no number
key is pressed within 5 seconds, the keypad clears the PIN code entry
buffer, generates a medium length beep and is ready to receive a new
6-digit keypad PIN code.
(EP) AAAA BBBB CCCC DDDD EEEE FFFF (OP)
Where:
A = The first key entered D = Fourth key entered
B = Second key entered E = Fifth key entered
C = Third key entered F = Sixth key entered
