18 AY-x55 Family Installation and Programming Manual
The Facility code is set in Programming Menu number four and can be
in the range 000 to 255. The factory default setting for the Facility
code is 000 (see Section 4.2.5).
The keypad PIN code can be one to five digits in length and can range
between 1 and 65,535. When entering a keypad PIN code that is less
than 5 digits in length, # must be pressed to signify the end of PIN
code entry. For keypad PIN codes that are 5 digits in length, on the
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 5-digit keypad PIN
code.
If the entry of the 1- to 5-digit keypad PIN code is disrupted and a
number key or # is not 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 = 16-bit code generated from keyboard
Option 6: 6 Keys BCD and Parity Bits, Wiegand 26-Bit
Option 6 sends buffer of 6 keys, adds parity and sends a 26-Bit Binary
BCD message. Each key is a 4-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, 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
