Application
As a small size moduel to be soldered onto different controller or card reader to add reading HID card function
Wiring drawing
Connect Pin
1 Power 5V
Antenna 2 Power ground
Antenna 3 Wiegand output D0(26 Bit)
4 Wiegand output D1(26 Bit)
5 RS232 format output
RS232 format:
The FUN pin is for RS232, the serial port setting is: 9600, n,8,1
Data format is as below: 0X2,D1,D2,D3,D4,D5,D6,D7,D8,0XD,0X3
Data is transferred with start flag 0X2, then 8 bytes card no# in ASCII code, 0XD+0X3 as end flag.
for example, one card with FC# code FF, and card No# FFFF, at the RS232 output pin, data will be:
0X2 32 35 35 36 35 35 33 36 0XD 0X3
