AYC-E/Q60 Series Installation and Programming Manual 27
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
4.2.3.7 Single Key, 3x4 Matrix Keypad (MD-P64)
This unique mode is intended to let the host controller scan the
keypad while still keeping the proximity card readers Wiegand 26-Bit
or Clock & Data formats active.
An optional interface board must be used between the AYC-E/Q60
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 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 keypad. 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 )
4.2.3.8 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.
