When a key is pressed, DATA1 is pulled "low" until the key is released
at which point DATA1 is set to "high". This allows the controller to
detect the duration of the key press.
The MD-P64 interface unit outputs the data received to 7 outputs
emulating a keyboard. The interface unit does not affect any data that
it receives from the proximity reader whether it is Wiegand 26-Bit or
Clock & Data.
Key pressed = ASCII Value
0 = '0' ( 0x30 hex )
6 = '6' ( 0x36 hex )
1 = '1' ( 0x31 hex )
7 = '7' ( 0x37 hex )
2 = '2' ( 0x32 hex )
8 = '8' ( 0x38 hex )
3 = '3' ( 0x33 hex )
9 = '9' ( 0x39 hex )
4 = '4' ( 0x34 hex )
*= '*' ( 0x2A hex )
5 = '5' ( 0x35 hex )
# = '#' ( 0x23 hex )

Option 8: 1 to 8 Keys BCD, Clock & Data
Option 8 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 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.
When using the keypad transmission format "1 to 8 keys BCD,
Clock & Data" (Option 8), an additional input is required to
specify the number of keys in the PIN code.
