As we all know, the serial port server is a data communication device that converts the serial port into a TPC/IP network interface. So what is TCP/IP? Although TCP/IP communication (and collecting data from TCP/IP devices) may seem intimidating at…
Industrial router remote communication application analysis
Q: What can the industrial router wireless client function achieve? The wireless client function of the industrial router can realize Wi-Fi bridging, which can be understood as a small relay function, but it is not completely equivalent to a relay.…

As we all know, the PPPoE protocol of industrial routers is a common dial-up Internet access method. So what is its principle? PPPoE: DNS protocol The Internet is essentially just a very large computer network, and in many ways is…
How RS485 works
RS485 principle This principle, also known as ANSI/TIAEIA-485, TIA-485-A or TIA/EIA-485, is jointly defined by the Electronic Industries Alliance and the Telecommunications Industry Association. Simply put, it is a method used in balanced digital multipoint systems. Standards that define the…
Frequently Asked Questions about Inter-Serial Communication of Serial Servers
The serial port server mainly includes: a power circuit module, an ARM9 processor, a network port circuit module, and a serial port circuit module. The ARM9 processor includes the following interfaces: at least one network port circuit interface and at…
Where are RS232 serial servers commonly used? Will they continue to be used in the future?
In process control projects, communication problems between DCS and lower computer PLC or field instruments are often encountered. Many chemical plants now adopt a general contract plus subcontracting model when constructing. Each supplier provides its own control system (usually mostly…
Is the principle of serial communication based on flow control?
Serial communication method 2.1 Full-duplex and half-duplex modes If a data communication system uses different paths for the two transmission directions of data, such a system can work in full-duplex mode, and a system using full-duplex mode can send and…
How to lay out the 4g industrial routers in the project
Existing industrial routers are generally used in relatively harsh environments. Due to work needs, most of the time the router needs to run all day or for several months. In order to make the industrial router have a longer service…
What are the common PLC modules?
Traditional PLC uses ladder diagrams and statement lists to make programming easy, and has the advantages of short system software development cycle and on-site debugging of programs. Traditional PLCs also have the disadvantages of being unable to support communication interfaces…
