• USB Cable × 1
• Dupont Wires

Wiring Diagram

The wire definition of UHF RFID MODULE-RS485 is:

• red：Input 7V/2A
• black：GND
• green：A end
• yellow：B end

Sample Code

This sample shows that use Arduino to control the status exchanging between "Stop reading tags" and "Restart tag identification function”.

unsigned char StopReadCode[5] = {0xa0,0x03,0xa8,0x00,0xb5};//Stop reading the label code
unsigned char ResetCode[5]={0xa0,0x03,0x65,0x00,0xf8};//Reset code
unsigned char StopReadCodeCB[6]={0xe0,0x04,0xa8,0x00,0x00,0x74};//Stop reading code success and return the value
unsigned char ResetCodeCB[6]={0xe4,0x04,0x65,0x00,0x00,0xb3};//Reset code success and return the value
unsigned char data[6]={};
void setup()
{
  Serial.begin(9600);
}

void loop()
{
  int i;
  int n=1;
  delay(2000);
  while(n)
  {
    Serial.write(StopReadCode,5);
    delay(200);
    if(Serial.available())
    {
      for(i=0;i<6;i++)
      {
        data[i]=Serial.read();
        delay(1);
      }
      for(i=0;i<6;i++)
      {
        if(data[i]==StopReadCodeCB[i])
          n=0;
        else
          n=1;
      }
    }
    delay(500);
  }
  n=1;
  while(n)
  {
    Serial.write(ResetCode,5);
    delay(200);
    if(Serial.available())
    {
      for(i=0;i<6;i++)
      {
        data[i]=Serial.read();
        delay(1);
      }
      for(i=0;i<6;i++)
      {
        if(data[i]==ResetCodeCB[i])
          n=0;
        else
          n=1;
      }
    }
    delay(500);
  }
