Single Key, 6-Bit Wiegand, Nibble & Parities
Each key press immediately sends 4 bits with 2 parity bits added.
Even parity for the first 3 bits and odd parity for the last 3 bits.
0 = 0 0000 1 6 = 1 0110 0
1 = 0 0001 0 7 = 1 0111 1
2 = 0 0010 0 8 = 1 1000 1
3 = 0 0011 1 9 = 1 1001 0
4 = 1 0100 1 = 1 1010 0 = "B" in Hexadecimal
5 = 1 0101 0 # = 1 1011 1 = "C" in Hexadecimal
Single Key, 8-Bit Wiegand, Nibbles Complemented
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
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 page 19 for more information on "Changing the
Facility Code")
