Option 2: Single Key, Wiegand 6-Bit Nibble and 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 = "A" in Hexadecimal

5 = 1 0101 0 # = 1 1011 1 = "B" in Hexadecimal

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 7.2.6).

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.



or # are pressed 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.
