Engineers often find themselves with insufficient cable length to connect end devices with RS232, RS422 and RS485 interfaces to their computers or controllers. How to solve this problem? There are many ways to expand the RS232, RS422 and RS485 interface…
Как NB-IoT может обеспечить лучшие решения для Интернета вещей
Traditional 4G wireless networks offer more capabilities than these use cases require. Additionally, IIoT applications require seamless coverage in remote environments, where staying connected consumes battery power and shortens device life. With the advent of 5G and NB-IoT, the ratio…
IoT Cellular Networks, What Are Our Options?
Cellular networks are changing and some are dying. At the recent 11th Global Mobile Broadband Forum (MBBF), Miao Shouye, leader of China Unicom’s 5G co-construction and sharing working group, revealed the latest clear incident of China Unicom’s 2G network withdrawal.…
What is the difference between 5G and 4G
5G (fifth generation network) is under development. Promising to deliver blazing-fast speeds and eliminate congestion, the technology promises to revolutionize mobile networks and create new economic opportunities: but, how will it do this? How will it differ from 4G? The…
Где зародился сотовый IoT?
The proliferation and popularity of IoT devices has led to the rise of low-power, wide-area network (LP-WAN) options such as SigFox, LoRa, and Weightless. Traditional cellular options, such as 4G and LTE networks, consume too much power. Furthermore, they are…
В чем разница между Ethernet и последовательной связью
In an era when RS232 ports were common, it was by far the most common method of bit-by-bit communication, so much so that the term “serial port” became synonymous with “RS232 port.” Using the word “serial” in conjunction adds to…
Принципы передачи цифровых сигналов на физическом уровне
There are many ways to implement the physical layer. Network equipment offers a wide range of connectivity options. Certain networks are well defined using the OSI model, where cables, bridges, industrial routers, serial servers, DTUs, and PCs can be easily…
Four important components of an Industrial IoT strategy
“The four main parts of any IIoT system are smart assets, data communications infrastructure, analytics and applications to interpret the data and act on it, and people. Smart assets include machines or other assets with sensors, processors, memory, and communications…
Can digital isolators protect RS232/RS485/CAN buses?
In industrial networking control, power conditioning, and point-to-point communication applications between computers, data is sent on the serial communication bus for various types of physical networks, such as RS232, RS485, and controller area networks. Each interconnected system typically has its…
Профессиональный анализ разницы между последовательными интерфейсами RS232 и RS485
Since the advent of the USB interface, the number of serial ports installed on serial devices and computer hosts has decreased, but serial interfaces are still widely used in industrial networking environments or commercial projects. There are dozens of serial…
