AY-x55 Family Installation and Programming Manual
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
#
are 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.
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.
