5.3.7 Option No. 7: Single Key, 3x4 Matrix Keypad (ARD-
MDP64)
This unique mode is intended to let the host controller scan the
ARD-AYCE65B keypad while still keeping the proximity card
readers 26-Bit Wiegand or Clock & Data formats active.
An optional interface board must be used between the ARD-
AYCE65B and the host system. Each key press is immediately
sent on DATA0 as an ASCII character at a baud rate of 9600 bits
per second.
When a key is pressed DATA1 is pulled "low" until the key is
released at which point DATA1 will be set to "high". This allows
the controller to detect the duration of the key press.
The ARD-MDP64 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
5.3.8 Option No. 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.
