What is an Ethernet to RS485 converter

Ethernet to RS485 converter is a protocol conversion device, which is somewhat similar to the communication management machine used in power stations.The RS232/485/422 serial port can be converted into a TCP/IP network interface,The bidirectional and transparent data transmission between RS232/485/422 serial port and TCP/IP network interface is realized.The serial port equipment can immediately have the function of TCP/IP network interface and connect the network for data communication.The communication distance of the serial port equipment is greatly expanded.

Ethernet to RS485 converter function

1. Ethernet to RS485 converter can connect traditional RS232/422/485 devices to the network immediately.Ethernet to RS485 converter is like a microcomputer with CPU, real-time operating system and TCP/IP protocol.Transmit data between serial ports and network devices. The Ethernet to RS485 converter can be used anywhere in the world, over a 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. Ethernet to RS485 converter allows you to reduce your workload instead of increasing it.First of all, a high-quality Ethernet to RS485 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 Ethernet to RS485 converter can use a single interface to complete all 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.

Configuration of Ethernet to RS485 converter

Step 1: In the case of working mode confirmation, you can select Quick Setup to enter the quick configuration mode after logging in.Modify the IP address of this machine, configure the baud rate of all serial ports and other parameters, and select RS232 or RS485 protocol.Select Save after setting.

Step 2: If you want to modify the configuration parameters of the serial port, select "Serial Setting" and click the corresponding serial port for data configuration.Here, the baud rate is 4800, 9600, or 38400.8 data bits, 1stop bit, no check bit, no flow control, FIFO set to Disable, protocol selection RS232 or RS485 (two-wire system),Finally, save the data.

Ethernet to RS485 converter connection

Direct connection mode: direct connection is to directly connect the network cable port on the computer with the Ethernet port on the Ethernet to RS485 converter.The networking mode is simple in wiring and can realize long-distance transmission.This is due to the increased distance from the computer to the Ethernet to RS485 converter.The production of the network cable is the same as the wiring of the network cable used for general Internet access.The serial port on the Ethernet to RS485 converter is mapped to COM3, COM4, etc. Through the virtual serial port management software.It can be operated like a normal serial port.For the Ethernet to RS485 converter, if a MAX485 chip is added to its TTL serial port, it will become RS422 or RS485.It can also be mapped to COM3, COM4, etc.,Therefore, no matter what kind of serial port mode the Ethernet to RS485 converter outputs to the host computer,Its operation mode is the same as that of the COM1 and COM2 ports of the computer itself, which greatly simplifies the programming workload of the upper computer.The real advantage and value of Ethernet to RS485 converter is not reflected in the application of direct connection mode.Connecting devices to Ethernet is an important part of its purpose.

Ethernet connection mode: connect the serial port device to the Ethernet through the Ethernet to RS485 converter.Its wiring method is very simple, only need to connect the Ethernet to RS485 converter to the router or switch.By setting the IP of the Ethernet to RS485 converter.Address (the product of XUNWEI brand is turned on to obtain DHCP dynamically by default, and it can obtain IP address automatically).The Ethernet to RS485 converter can be made a node on the Ethernet,O that devices connected to the Ethernet to RS485 converter are connected to the Ethernet,Through the networking mode, different devices and different forms of serial ports can be connected.(Such as TTL, RS232, RS485 and RS422), connect to Ethernet to realize heterogeneous networking.This networking mode can connect the equipment of the whole company to the network. During the networking process,In addition to taking advantage of switch and router extensions, you can also take advantage of industrial Ethernet switches,Different types of Ethernet to RS485 converters are extended to realize flexible networking of equipment.The staff can monitor the equipment according to their authority and level.From company leaders, chief engineers, technical leaders to ordinary operators, they can monitor the system within their own authority.It realizes the sharing of network resources and the centralized management of all systems, and builds a platform for network manufacturing technology.
