Keypad Programming Instructions (AY-Q6350)
AY-Q6x50 Family Installation and Programming Manual

5.9.2
Clock and Data
In this mode, 4 bytes of card serial number are transmitted in Clock &
Data format.
5.9.3
Wiegand Card + PIN Transmission Format
This unique mode is intended to let host controllers get card and
keypad data simultaneously. This option overrules the selected
Keypad Transmission Format and sends the keypad data as described
below.
The AY-Q6350 output data turns into a virtual 52-bit Wiegand – 26-
bit card data followed by a 26-bit keypad data.
After a card is presented to the AY-Q6350, the Transmit LED starts to
flash red to indicate that the AY-Q6350 is waiting for the PIN code.
The entered PIN code is buffered up to 5 keys and outputs keypad
data with a Facility code much like Option 5 (1 to 5 Keys + Facility
Code, 26-Bit Wiegand) (see Section
5.7.5).
5.9.4
Wiegand 26-Bit and Facility Code
In this mode, a 1 byte Facility code followed by 2 bytes of the card's
serial number are transmitted in Wiegand 26-Bit format. Two parity
bits are added. An even parity bit is sent first, followed by one Facility
code byte then followed by two bytes card serial number ending with
an odd parity bit.
(EP) FFFF FFFF AAAA AAAA AAAA AAAA (OP)
Where:
EP = Even parity for first 12 bits
OP = Odd parity for last 12 bits
F = 1 byte Facility code
A = 2 bytes code generated from card serial number.
The third and fourth bytes of the cards serial number is not
transmitted.
