Option 3: Single Key, Wiegand 8-Bit Nibbles Complemented
This option inverts the most significant bits in the message leaving
the least 4 significant bits as a Binary Coded Decimal (BCD)
representation of the key. The host system receives an 8-bit
message.
0 = 11110000 6 = 10010110
1 = 11100001 7 = 10000111
2 = 11010010 8 = 01111000
3 = 11000011 9 = 01101001
4 = 10110100  = 01011010 = "A" in Hexadecimal
5 = 10100101 # = 01001011 = "B" in Hexadecimal
Option 4: 4 Keys Binary + Facility Code, Wiegand 26-Bit
This option buffers 4 keys and outputs keypad data with a 3-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 Section 3.2.6).
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  or # are pressed during PIN code entry, the keypad clears 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-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 beep, and is ready to receive a new
4-digit keypad PIN code.
