Rosslare AYC-Ex5 Instruction Manual page 25

The MD-P64 interface unit outputs the data received to 7 outputs
emulating a keyboard. The interface unit will not affect any data
that it receives from the proximity reader whether it is 26-Bit
Wiegand or Clock & Data.
Key pressed = ASCII Value
0 = '0' ( 0x30 hex )
1 = '1' ( 0x31 hex )
2 = '2' ( 0x32 hex )
3 = '3' ( 0x33 hex )
4 = '4' ( 0x34 hex )
5 = '5' ( 0x35 hex )
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 long. The PIN
code length is selected while programming the reader for Option
8. The reader will transmit 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 the " " key or the "#" key are pressed during PIN code entry, the
keypad will clear the PIN code entry buffer, generate a beep and
is ready to receive a new keypad PIN code.
If the entry of the digit keypad PIN code is disrupted and no
number key or "#" key is pressed within 5 seconds, the keypad will
clear the PIN code entry buffer, generate a medium length beep
and is ready to receive a new keypad PIN code.
