In the multi- TCP link connection mode, data from TCP will be forwarded one by one to the serial port. -
Page 20: Serial Frame Scheme
4G_2G DTU Products Function Figure 21. Specify Socket Channel Communication Transmission 1.7. Serial Frame Scheme When the DTU receives data from the UART, it constantly checks the interval between two adjacent bytes. If the interval is greater than a certain value, then one frame is considered to have ended, otherwise the data is received until the buffer byte (512 bytes). -

Page 22: Iotservice Software
4G_2G DTU Products Function 1.9. IOTService Software DTU enables the High Flying’s IOTBridge cloud management function by default. Through the IOTBridge cloud platform, the IOTService configuration tool can be configured in a network configuration (this will consume a certain amount of traffic. If it is enabled 24 hours, it can be configured at any time, and the traffic consumption is about 30MB/ Month), you can choose to turn off this feature or set only a specific time period to save to save traffic. - Page 23 4G_2G DTU Products Function 2）Open the serial port tool. 3）Open the serial port according to the current device serial port parameters, click to read the parameters, and the sidebar will display the AT command of the reading process. 4）After reading, the interface displays the working status of the current module. If you need to modify the parameters, click Confirm Setting to modify it.
