What is passthrough?
Transparent transmission, the full name of transparent transmission, refers to a data transmission method that has nothing to do with the medium, modulation, demodulation method, transmission method, and transmission protocol of the transmission network.
Transparent transmission is transparent to the outside world during the transmission process, which means that you cannot see that it is a transmission network. Regardless of the transmitted business, I am only responsible for transmitting the business that needs to be transmitted to the destination node, which is equivalent to a data line or a serial port line. At the same time, just ensure the quality of the transmission without processing the transmitted business. This is like express mail. It may reach you through a variety of combined transportation methods, such as cars, trains, and airplanes, but you don’t need to care about the processes they go through.
Why should we choose transparent transmission for IoT communication?
Transparent transmission is generally used to read remote serial port data. In the Internet of Things era where things are connected, if you want to realize data transparent transmission of smart devices, you need to rely on the power of wireless transparent transmission module, which can achieve the same length and content of the sender and receiver data without any processing of the data, equivalent to a data line or serial port line, is widely used in the Internet of Things industry, such as smart grids, smart transportation, industrial automation, smart buildings, environmental protection, smart agriculture, smart water, smart homes, etc.
Recommended transparent transmission module
In response to the growing demand for data transparent transmission, Zongheng Intelligent Control has launched an industrial-grade DTU transparent transmission module. Through simple settings on the host computer, you can easily use this product to achieve bidirectional data transparent transmission from the serial port to the network. The operation is stable and reliable, and can be widely used in power systems, industrial monitoring, traffic management, environmental monitoring, meteorology, water conservancy, coal mines, petroleum, new energy and other industries, providing strong support for communication networking and wireless transmission of projects.
