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. Its functions are similar to

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 communication status, and sends terminal

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

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 impact on the NB-IoT Internet

LoRa Alliance There is a movement to standardize LoRa’s MAC functionality, called the LoRa Alliance. The LoRa Alliance developed the LoRaWAN protocol for use by mobile network operators that use unlicensed spectrum to communicate with IoT devices in their networks. LoRaWAN is ideally suited for

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 keep the internal processes of

In the early days, serial port server products were large and required a lot of resources for processing. With the development of technology, new integrated circuit designs have been made, thereby reducing the size of the serial server. This facilitates the upgrade of serial device

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 module. The main performance of

The Internet of Things (IoT) is an interconnected network of physical items embedded with software and connectivity that enables these objects to collect and exchange data, ushering in the fourth industrial revolution. Smart manufacturing is making waves across all industries. Smart manufacturing has unprecedented potential

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 about the protocol. The RS232
