1. A new generation of high-performance ARM-COTEXM3 processor, the product is powerful, with built-in master-slave mode, automatic mode, channel door mode, and more scalability to meet customer needs;
2. Using industrial-grade chip design, and adding an external watchdog circuit to improve product reliability;
3. Excellent performance, with 8dBi antenna to read a single tag can reach more than 28 meters (related to tag type, transmission power and application environment);
4. Integrates the functions of network port, Mini USB, RS485, WIFI (optional), and integrates rich communication interfaces, which is convenient for users to choose the appropriate interface for connection and use. The Mini USB interface can be connected at any time, which is convenient for configuring device parameters. If the two communication ports of the serial port and the network port are connected normally, the same label data can be read at the same time. If the network is not connected successfully, data can be transmitted through the serial port;
5. When the original network port connection is disconnected, it has the device buzzer alarm failure reminder function. At the same time, the indicator light is designed with a flashing alarm function;
6. 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 After working hours, it will stop automatically. The card reading method can be set to read only one card and then stop or read continuously;
7. The radio frequency part adopts carrier suppression technology, which has strong anti-interference ability;
8. Provide a full-featured software development kit (SDK) and interface (API) to facilitate the integrated development of RFID software;
9. Provide easy-to-operate server software for quick use and configuration of our equipment;
10. Using ultra-high isolation technology, it perfectly solves the problem of serial reading between ports.

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.
