The Ethernet to serial converter is a small electronic device that converts Ethernet IP/TCP packets into serial data signals for bidirectional data communication. Two-way data communication, that is, the data packet can be transparently transmitted from the Ethernet port to the serial data port, and the data packet of the serial data port can also be transmitted to the Ethernet port. Why is it transparent transmission?Because in the transmission process, the data is not processed by the protocol, what data is sent, what data is received.

  Principle of rs 232 to Ethernet converter

  The RS232 to Ethernet converter is a kind of Ethernet to serial converter, which has an RS232 serial port in its serial port. So the principle is the same as the Ethernet to serial converter. Because RS232 serial port has been developed very well, RS232 interface is called "one of the most popular interface modes of peripheral equipment" in the world, and it can afford the solution of integration of software and hardware communication.

  Where is the RS232 serial port commonly used? Will it continue to be used in the future?

  Most modern electronic instruments, including measuring tools and laboratory instruments (balances, electrochemical meters, spectrometers, spectrophotometers, etc.) Are connected to a computer using a standard RS232 serial port cable. The RS232 protocol has been around for many years, and many cost-effective hardware and software solutions have been established.More than 90% of computers are equipped with at least one RS232 port with an additional adapter. There are also hundreds of software applications that can be used to communicate with the instrument via an RS232 connection. Because of the flexibility and ubiquity of the RS232 standard, it is likely to remain relevant in the future.

  What is the limitation of RS232 communication?

  The problem with RS232 communication is that it requires a point-to-point serial line connection for transmission, and the distance of the serial line is limited. This requires each instrument that communicates with it to be connected to a unique RS232 port on the PC using a separate serial port line. If you want to connect multiple devices to a single PC, you must install multiple RS232 ports on the PC.

  If the RS232 standard is to be improved, it will allow multiple connections over a single serial line, with no limit on serial line length, and will remain 100% compatible with all existing RS232 communication software.

  Is there a way to improve it?

  Fortunately, there is a very simple way to do this. Through the virtual serial port software, the original local serial port control function is extended, and you do not need to modify the original serial port program, you can still use it.

  The virtual serial port application software (USR-VCOM) can map the TCP/IP connection, UDP broadcast and devices connected to the cloud to the local virtual serial port, and the application program can complete remote control, data transmission and other functions by accessing the virtual serial port.

  Does the virtual serial port software cost money?

  The virtual serial port software on the market is usually free of charge, but the practicality of the software is uneven.The serial port virtual software USR-Vcom of PUSR is used in combination with Ethernet to serial converter, modems, Industrial router and other communication devices with serial ports to support multiple virtual serial port mappings. Support multiple network protocols such as TCP Client, TCP Server and UDP, and real-time virtual serial port data transmission monitoring.
