Applying development of unilateral communication | VI-88TR development handbook
Wiegand interface has 2 types of Wiegand26 and Wiegand34.
1.2.1 Wiegand26 format
Wiegand26 transmits 26 bits data every time, 24 bits of them are valid. We
stipulate these 24 bits correspondent for low 24 bits of electronic tag ID, or
user defined number. Transmission format as follows:
Even: verified data adds parity bit1 is even number.
Odd: verified data adds parity bit1 is odd number.
1.2.2 Wiegand34 format
Wiegand34 transmits 32 bits of valid data every time. We stipulate these 32
bits correspondent for low 32 bits of electronic tag ID, or user defined
number. Transmission format as follows:
1.3 RS485 interface agreement
When adopt RS485 interface to output data, need to set up communication
rate of RS485 interface in advance. Output data format of RS485 is:
