1. Based on a new generation of high-performance ARM-COTEXM3 processor;
2. The device is designed with 6 IO ports (4 outputs and 2 inputs) for users to expand applications: 2 input IO ports can be set to trigger and read EPC, can set high/low level trigger, reverse stop; or can set after trigger It will stop automatically after working for a period of time. The card reading method can be set to read only one card and then stop or read continuously;
3. When the original network port connection is disconnected, it has the device buzzer alarm failure reminder function, and the indicator light is designed with a flashing alarm function;
4. The equipment has been strictly tested before leaving the factory to ensure product quality;
5. With 8dBi antenna, the reading distance of RFID tags is 0~20m;
6. Multi-tag intensive reading performance can achieve a tag recognition rate greater than 800tags/s;
7. Provide a full-featured software development kit (SDK) and interface (API), easy to integrate with system software;
8. Using integrated radio frequency modules, the performance is more stable, and it is more suitable for harsh and demanding application environments;
9. The module adopts carrier cancellation technology, the accuracy of tag reading is better and the range is wider;
10. Enhanced noise suppression for reliable data capture;
11. High precision return signal strength (RSSI);
12. Excellent anti-interference performance.

Simple fault description and troubleshooting

Run light flashing prompt:

1. Start and run 800ms on, 700ms off;
2. The wired network connection is successful (or the WIFI network connection is successful, or the 4G network connection is successful), 160ms on, 140ms off;
3. When entering the MQTT connection state, the blinking speed increases by 5 times on the basis of a successful network connection.

Buzzer prompt:

1. The WIFI/4G/wired network connection is successful, and the buzzer will sound 3 consecutive times, with an interval of about 50ms;
2. The MQTT connection is successful, and the buzzer sounds 3 times in a row, with an interval of about 20ms;
3. After the wired network connection is successful, if an abnormal disconnection occurs, the buzzer will beep for a long time, with an interval of 500ms;
4. The parameter is set successfully, the buzzer will sound twice continuously, and the time interval is about 50ms;
5. After restoring the system settings, the buzzer will sound 3 consecutive times with an interval of about 80ms;
6. The self-test of the power-on module fails, and there are 2 consecutive beeps, with an interval of 800ms;
7. The self-test of the power-on module is successful, and the buzzer will sound once for 200ms;
8. The connection module is a Rodin module, and it sounds 3 times in a row with an interval of 100ms.
