Auxiliary Asynchronous Serial output
If selected, data can be automatically output from the OP0 or main TX pin as 4-bytes of data
transmitted asynchronously at 9600 baud, 8-bits, 1 stop-bit, no parity. The data source can be
selected as the 4-byte UID (serial number), the least significant 4-bytes of a double UID or
the least significant (first) 4-bytes of a card memory block.
Data bytes transmitted at 9600 baud, 8-bits, 1-stop bit, No parity (104 μ S per bit)

Auxiliary Wiegand Output Protocol
If selected, data can be automatically output from the OP0 / OP1 pins as Data HIGH and
Data LOW signals according to the Wiegand protocol.
The Wiegand protocol (24 bit data length) can be made up of a leading even parity bit (for b0
- b11), 24 bits of data (from transponder data) and a trailing odd parity bit (for b12- b23)
creating a 26 bit output stream. The 32-bit mode has the same format except least significant
four bytes of block data are used to form the data sequence. The parity bits are included or
omitted and the byte order is reversed according to the EEPROM parameter settings.
For Example:-
Mifare block data (least significant 4 bytes): 0x04 60 22 12
(reversed byte option would use 0x12 22 60 04 as base data)
Wiegand 26 bit sequence:-

Where E is EVEN parity bit for bit 0 to 11 and O is ODD parity bit for bits 12 to 23
The base data for the Wiegand output can be the UID (least significant 4-bytes of serial
number) acquired during the initial ISO14443A communication or the least significant
4-bytes of data from a block of card memory (acquired by an internal Block Read
operation). Selection is by means of an RWD EEPROM parameter.
For the internal Block Read operation, the block number, key code number and type (KeyA or
KeyB) are programmable EEPROM parameters. In addition, parameters control whether the
base data byte order is reversed or if parity bits are added before output.
