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…

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…

Uso básico de DTU DTU inicia una solicitud de comunicación TCP/IP al centro de datos a través de la dirección IP, el número de puerto y otros parámetros del centro de datos. Tras recibir la respuesta del servidor remoto, DTU implementa los requisitos de red remota, mantiene los datos...

GPRS DTU is also called gprs data transmission terminal. It is a gprs networking device formed by the gprs module embedded on the circuit board and a sheet metal shell. It is a wireless version of the serial port server.…

Two-way communication Usually the serial port on the PC is a full-duplex device, which means it can send and receive data at the same time. To do this, it uses separate lines to send and receive data. Some types of…

Internet of Things (IoT) – Essential IoT Business Guide The Internet of Things (IoT) is changing the way we live, work, travel and do business. It is even the basis for the new industrial transformation, namely Industry 4.0, and is…

There are many advantages to using an industrial router, DTU or switch, but as with any network connection, security is one of the most important elements when designing your system. We’ll look at several areas and where security gaps may…

As Internet of Things (IoT) applications expand, the scope of their associated networks must also expand. While Wi-Fi, Bluetooth, and Zigbee are available for convenient wireless networking near or within industrial facilities, some Industrial Internet of Things (IIoT) networks require…

How the serial port server works After the invention of the USB protocol, serial port devices are rarely seen in our lives. For this reason with modern transmission systems, most manufacturers no longer add serial ports to laptops, desktop computers,…

In radio technology, basically three characteristics can be used to characterize a radio network: ● Range/distance ● Data transfer speed ● Power consumption. The criteria for these three indicators are certainly not the same, since the laws of physics set…

As we all know, serial port devices are still widely used in various industrial scenarios. However, when there is only a USB to 232 communication line, the serial device can be connected. When there is no USB to RS232 communication…

In the context of Industry 4.0 and Made in China 2025, China’s industry is accelerating intelligence and informatization. Its main manifestation is that traditional enterprises realize unmanned office work through IoT wireless technology. For example, assembly line work that was…
