Applying development of unilateral communication | VI-88TR development handbook
1 Applying development of
unilateral communication
1.1 Applying development of unilateral
communication
Apply in software development of continuous and trigger working mode,
upper computer only need to receive tag ID numbers sent by reader, no
need to send reader command.
1.2 Wiegand interface agreement
Wiegand interface transmites unilaterally, can send read card numbers to
controller only, but controller can not send signal to reader. Signal
transmitted from wiegand interface as follows:
D0
D1
0 0 0 01
+5V
0V
0V
+5V
Pulse Interval
2ms
Pulse Width
400us
Binary
Number
At present, output waveform from Wiegand interface is as follows:
A. 400us in pulse width,2.0ms in pulse interval
B. 100us in pulse width,1.6ms in pulse interval
C. 50us in pulse width,1.0ms in pulse interval
