summarize
The term DTU is often mentioned in the IoT industry, what exactly is a DTU, and the IoT needs to bring thetransducersThe signals are sent to the cloud for display, which requires a variety ofserial port dataConvert to IP data or convert IP data to serial data; only then can it be used over wireless communication networks (3G, 4G, 5G.),WiFi, NB, Lora,ZigBee), transmits data to a remote server via HTTP, TCP, UDP, MQTT, and other protocols.
Difference between DTU and Serial Server
When it comes to DTUs, we can't help but involve another product: serial servers. Serial server is basically a server that converts any serial device into an Ethernet-enabled device that can be used in a network, and one of the hardware features is that the serial server has a network cable interface, which explains that a DTU is a serial server that can be networked.
The English name of DTU becomes: Data Transfer Unit; Chinese can be straightforwardly said to be a data transfer unit, which is specially used to convert serial data to IP data or IP data to serial data for wireless data acquisition device, which is transmitted through wireless communication network.

Application Areas
DTUs can be divided into four types according to the different data transmission methods of DTUs: GPRS DTU, WIFI DTU, CAN DTU, 4G DTU, Lora DTU, ZigBee DTU, which are widely used in various industries such as smart city, smart agriculture, intelligent manufacturing, electric power, meteorology, water conservancy, geology and so on, and even though the application is different from each other, the application of the principle is largely the same; mostly DTUs and industry equipment are connected, such as PLC, microcontroller and other automation products, and then establish wireless communication connection with the background. Although the application industries are different, the application principles are similar; mostly DTU and industry equipment are connected, such as PLC, microcontroller and other automation products, and then wireless communication connection is established with the background. In the increasing development of the Internet of Things today, the use of DTU is also more and more extensive. It provides help for the information and industrial integration of various industries as well as between industries, and also gradually develops into a key technology for IoT applications.
World Power related DTU products
World Power has a wide range of DTU models to choose from, adapting to Modbus protocol, supporting RS485 and RS232 communication interfaces, and with a maximum transmission distance of up to 20km. some specific models use LoRa modulation technology, which makes the DTUs highly diffractive and penetrating, and meets a variety of data transmission needs.
