The RS485 Ethernet converter is simply a network communication interface conversion device,It can convert our common RS232, RS485 and RS422 serial ports into TCP/IP network interfaces.The bidirectional and transparent data transmission between RS232, RS485, RS422 serial ports and TCP/IP network interface is realized.The conventional serial port equipment can immediately have the function of TCP/IP network interface, so as to achieve the purpose of connecting the network for data communication.What is the working principle of RS485 Ethernet converter? What is the function of RS485 Ethernet converter to help us achieve?

Working principle of RS485 Ethernet converter

RS485 Ethernet converter makes it possible to transmit serial data stream based on TCP/IP.The invention can connect a plurality of serial port devices and select and process serial port data streams,The data of the existing RS232 interface is converted into the data of the IP port, and then the IP-based management and IP-based data access are carried out.In this way, traditional serial data can be sent to the popular IP channel without prematurely replacing the original equipment.Thereby improving the utilization rate of the existing equipment, saving the investment and simplifying the wiring complexity on the basis of the existing network.RS485 ethernetThe converter completes the storage control of communication data between a connection-oriented RS232 link and a connectionless Ethernet,The system processes all kinds of data, processes the serial port data stream from the serial port equipment, and converts the format.Make it a data frame that can be propagated in Ethernet; The data frame from the Ethernet is judged,And converted into serial data and sent to the responding serial port device.

Function of RS485 Ethernet converter

1. RS485 Ethernet converter can connect traditional RS232/422/485 devices to the Internet immediately.The serial device networking server is like a microcomputer containing CPU, real-time operating system and TCP/IP protocol.Transmit data between serial ports and network devices. The RS485 Ethernet converter can be used anywhere in the world, through the network,Use your computer to access, manage, and configure remote devices. An electrical device having only a serial interface,Such as POS, ATM, display screen, keyboard, card reader, card reader, switch, minicomputer, refueling machine, RTU, CNC machine tool and testerThe microcomputer protection device can be easily connected to Ethernet to realize network management and remote control.

2, RS485 Ethernet converter, allows you to reduce the work rather than increase the workload.First of all, a high-quality RS485 Ethernet converter will have a "friendly management interface".These numerous serial devices may be located at different remote locations,Therefore, it is an important indicator that the high-quality serial converter can use a single interface to complete all the settings.Whether using Windows software, the Web, or Telnet.With high performance and low latency, 115.2Kbps is enough for some traditional serial transmission applications.However, if you want to switch to 100m interface converter communication, the speed of the embedded device module is 230.4kbps, which will be more secure.

The RS485 Ethernet converter saves resources and costs in the following areas:

1. Cable cost savings: RS485 RS485 Ethernet converter uses differential signals to transmit data, compared with the traditional RS232 serial port.It can effectively reduce the use of cables, and use simpler and cheaper cables and connectors, thus reducing the cost of cables.

2.System resource utilization: RS485RS485 Ethernet converter can realize multiple serial devices through one RS485 EthernetInstead of requiring each device to be configured with a separate serial port.This centralized management can save the use of system resources and reduce the waste of hardware devices and serial port resources.

3. Remote management cost: RS485 Ethernet converter can remotely manage and control serial devices through the network.In this way, the frequent operation of equipment by on-site personnel can be avoided, and the labor cost and the need for on-site maintenance can be reduced.

4. Improved flexibility and scalability: Serial devices can be connected to the network through the RS485 Ethernet converter.Increase the flexibility and scalability of the device.The remote access, monitoring and control of the equipment can be conveniently realized, and the equipment can be conveniently integrated into other systems.

In general, the RS485 Ethernet converter provides a more flexible, efficient, and convenient way to access serial devices.Thereby saving cable cost, system resource utilization and remote management cost, and improving the flexibility and expandability of the equipment.
