From the current point of view, Shanghai is the first city in China to fully offline narrowband dial-up Internet access. This may also mean that the already pitiful narrowband dial-up Internet service will become a thing of the past: a year ago, on August 17,

In serial communication, data is sent one bit at a time over a signal line, so in order for the receiving end to receive the data accurately, the sending end must know the sending data for each bit.在RS232中，同步已经定义了

The Internet of Things involves extending internet connectivity to anything from standard devices like traditional desktops, laptops, smartphones and tablets to connecting physical devices and everyday objects that are not internet-enabled. These devices are embedded with program technology, can communicate and interact through the Internet,

RS-232C, RS-422A, and RS-485 are communication standards of EIA (Electronic Industries Association). Among these communication standards, RS-232C has been widely used in various applications and even as standard equipment on computers, and Often used. Used to connect to serial servers or DTU devices. Usually sensors

What is serial communication? The academic explanation is a method of continuously sending one bit of data through the bus at a point in time. Just like an archer shooting his bow and arrow frequently, whoosh, whoosh, whoosh… What is the serial communication protocol? To

Computer technology has been with us since the mid-20th century. However, the technology behind the Internet of Things has been mature since Tom, Dick and Harry all started using PCs. Telemetry science, the earliest representation of the Internet of Things, has been used since the

Industrial routers are connected through cellular network data, so they are more suitable for outdoor and commercial indoor use environments. There is no need to consider the troublesome problem of wiring. They only need stable signals and the stronger the better. We can also use

Industrial routers can be installed indoors or outdoors, in corners or on desktops, in mountains or underground, and anywhere there is a signal. But to ensure the best performance from your industrial router, it’s best to choose a good location to get the signal and

The Internet of Things (IoT) networks will massively expand the use of mobile communications beyond smartphones and tablets to an extraordinary range of applications and connected devices – including many products that have yet to be invented. While many IoT applications require only short-range wireless

The Internet of Things (IoT) is considered to be the third wave of development of the world’s information industry after computers and the Internet, and is also called the fourth technological revolution . At present, most of the Internet of Things still rely on the

Local area networks such as WiFi or Bluetooth are already mature technologies. There are well-established standards for this type of small wireless communication, such as WiFi, Bluetooth 4.0, Zigbee and Z-Wave. But the biggest problem with many LANs/Personal Area Networks are battery consumption. Similar to

What is a serial to ethernet device used for? The main purpose of this tool is to provide communication between serial devices and computers through its COM port, which recognizes the signals sent by the serial port over Ethernet. In practice, this means that using
