What is RS232 protocol? The RS232 protocol is a popular serial interface used to connect computers to networked devices such as serial servers. We will look at the serial port pins used to implement RS232 and some other reference information…
The difference between 4g module and dtu module
The 4g module is a cellular communication device that uses two standards, TD-LTE and FDD-LTE, and is loaded into a designated frequency band. The software supports the basic circuit set of the standard LTE protocol and is an IoT communication…
How watchdog protection works
In order to make the transmission of networking equipment such as industrial routers, DTUs, and serial servers more stable, these devices will be equipped with anti-surge, anti-static, anti-pulse and watchdog protection. Among these hardware protections, there is one that can…

Starting from the analysis of NB-IoT Internet of Things technology, it introduces the physical layer of the NB-IoT system and its coexistence with other systems, introduces the LTE system and GSM system, and analyzes the necessity of research on their…
Advantages of LoRa in Cellular and LAN
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…
LoRa network architecture
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…
Does gprs dtu require a card?
Basic usage of DTU DTU initiates a TCP/IP communication request to the data center through the data center’s IP address, port number and other parameters. After receiving the response from the remote server, DTU implements remote networking requirements, maintains data…
The working principle and application scenarios of GPRS DTU
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.…
Common communication methods in the Internet of Things
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…
How does the Internet of Things change our lives?
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…
Security factors that need to be considered when using 4g industrial routers
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…
How industrial router-type cellular equipment improves efficiency
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…
