6.3.1.3
Single Key, 8-Bit Wiegand, Nibbles Complemented
This option inverts the most significant bits in the message leaving the
least 4 significant bits as 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
6.3.1.4
4 Keys Facility Code, 26-Bit Wiegand
This option 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 Section
6.6).
The keypad PIN code must be 4 digits 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 clears the PIN code entry buffer, generates 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.
