Option 5: 1 to 5 Keys + Facility Code, 26-Bit Wiegand
Buffers up to 5 keys and outputs keypad data with a facility code
like a 26-Bit card output.
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 Changing the Facility Code on page 25
for more information.) The keypad PIN code can be one to five
digits long and can range between 1 and 65,535. When entering
a keypad PIN code that is less than 5 digits long, the "#" key must
be pressed to signify the end of PIN code entry. For keypad PIN
codes that are 5 digits long, 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 the "*" key is pressed during PIN code entry or a PIN code
greater than 65,535 is entered, the keypad will clear the PIN code
entry buffer, generate 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 no
number key or "#" key is pressed within 5 seconds, the keypad will
clear the PIN code entry buffer, generate 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, 26-Bit Wiegand
Sends buffer of 6 keys, adds parity and sends a 26-Bit Binary-
Coded Decimal (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.
