Option No. 3: Single Key, 8-Bit Wiegand Nibbles

4 significant bits as Binary-Coded Decimal (BCD)
representation of the key. The host system receives an 8-bit
message.

5.3.4
Option No. 4: 4 Keys Binary + Facility Code, 26-Bit
Wiegand
Buffers 4 keys and outputs keypad data with a three digit
facility code like a standard 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
22 for more information.)
The keypad PIN code is 4-digit long and can range between
0000 and 9999. On the fourth key press of the 4 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 or the # key are pressed during PIN code entry, the
keypad will clear the PIN code entry buffer, generate a beep
and is ready to receive a new 4 digit keypad PIN code.
If the entry of the 4 digits keypad PIN code is disrupted and no
number key is pressed within 5 seconds, the keypad will clear
the PIN code entry buffer, generate a beep and is ready to
receive a new 4 digits keypad PIN code.
