1. Using ARM-CORTEX-M3 processor, the product has more powerful functions, more scalability, and can meet more customer needs;
2. Using industrial-grade chip design, and adding a watchdog circuit to improve product reliability;
3. Integrated Ethernet port, Mini USB, RS485, Wi-Fi (optional) function interface, 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;
4. When the original network port connection is disconnected, the buzzer of the device has an alarm fault reminder function, and the indicator light will flash to alarm at the same time;
5. 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;
6. The radio frequency part adopts carrier suppression technology, which has strong anti-interference ability;
7. Provide a full-featured software development kit (SDK) and interface (API), which is convenient for users to carry out integrated development of software;
8. Provide a simple and easy-to-operate server software for quick use and configuration of our equipment.

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 reminder

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, which sounds 3 times in a row with an interval of 100ms.
