Interface Description：
1) ANT antenna interface, solder 125KHz coil (490uH, 0.2 wire diameter recommended).
2) JP2 indicator interface, LED indicator, GREEN is the negative pole of the green light, RED is the negative pole of the red light, 5V is the output 5V of the small board, connected to the positive pole of the LED.
3) J5 is the serial port output, the 4 pins are: 5V, GND, RX (sending pin of the small board), TX (receiving pin of the small board), baud rate 19200, the card number sends 4 bytes continuously, the high byte is in front, and the byte interval does not exceed 50ms. The power supply and transceiver pins of the serial port are both 5V level.
4) JP1 power supply and Wiegand interface, 12V and GND are DC power input DC9-12V, D0 and D1 are Wiegand output, SET pin is Wiegand 26 and Wiegand 34 selection, if not connected it is Wiegand 26, if SET is connected to ground it is Wiegand 34; BEEP pin is buzzer test pin, if connected to ground the buzzer will sound, if not connected the buzzer will not sound; LED pin is indicator light test pin, if connected to ground the green light will light up, if not connected the red light will light up
