Proximity Card Transmission Formats
Option 1: Wiegand 26-Bit
In this mode, 3 bytes of card serial number are transmitted in
Wiegand 26-Bit format. Two parity bits are added. An even parity bit
is sent first, followed by three bytes card data than followed by odd
parity bit.
The fourth byte of the cards serial number is not transmitted.
(EP) AAAA AAAA AAAA AAAA AAAA AAAA (OP)
Where:
EP = Even parity for first 12 bits
OP = Odd parity for last 12 bits
A = 3 bytes code generated from card data
Option 2: Clock & Data
In this mode, 4 bytes of card serial number are transmitted in Clock
& Data format.
Option 3: Wiegand Card + PIN Transmission Format
This unique format 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-Q6360 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 unit, the Transmit LED starts to
flash red to indicate that the unit 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).
