User's Manual

If the entry of the 6 digit keypad PIN code is disrupted and no
number 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 6 digit keypad PIN code.
(EP) AAAA BBBB CCCC DDDD EEEE FFFF (OP)
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
Option 7: Single Key, 3x4 Matrix Keypad (MD-P64)
This unique mode is intended to let the host controller scan the
AYC- F/G/M60 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 AYC-
F/G/M60 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 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 ) 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 )
