Option 6: 6 Keys BCD and Parity Bits, Wiegand 26-Bit
Option 6 sends buffer of 6 keys, adds parity and sends a 26-Bit BCD
message. Each key is a four bit equivalent of the decimal number.
The keypad PIN code must be 6 key presses long. On the sixth key
press of the 6-digit PIN code, the data is sent across the Wiegand
Data lines as a BCD message.
If the entry of the 6-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 medium length beep and is ready to
receive a new 6-digit keypad PIN code.
(EP) AAAA BBBB CCCC DDDD EEEE FFFF (OP)
Where:
EP = Even parity for first 12 bits
OP = Odd parity for last 12 bits
A = The first key entered
D = Fourth key entered
B = Second key entered
E = Fifth key entered
C = Third key entered
F = Sixth key entered
Option 8: 1 to 8 Keys BCD, Clock & Data
Buffers up to 8 keys and outputs keypad data without a Facility
code like standard Clock and Data card output.
The keypad PIN code can be one to eight digits in length. The PIN
code length is selected while programming the reader for Option 8.
The reader transmits the data when it receives the last key press of
the PIN code. The data is sent across the two data output lines as
binary data in Clock & Data format.
If
or
#
is pressed during PIN code entry, the keypad clears the
PIN code entry buffer, generates a beep, and is ready to receive a
new keypad PIN code.
If the entry of the digit keypad PIN code is disrupted and a number
key or
#
is not pressed within 5 seconds, the keypad clears the PIN
code entry buffer, generates a medium length beep, and is ready to
receive a new keypad PIN code.
