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.
Note:
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.
Option 9: Single Key, 4-bit Wiegand
Each key press immediately sends 4 bits of data, with no parity bits
added.
0= 0000 6= 0110
1= 0001 7= 0111
2= 0010 8= 1000
3= 0011 9= 1001
4= 0100 *= 1010 ="A" in Hexadecimal
5= 0101 #=1011 ="B" in Hexadecimal
