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
4.2.3.6
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 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, 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.
