1 Port RS232/RS422/RS485 to Ethernet Converter | DB9 Male Port

View : 460
Type : Serial to Ethernet Converter
Description :

This product supports 1 channel of RS-232/RS-422/RS-485 to 1 channel of Fast Ethernet.


This product is an industrial din-rail type serial port server with IP40 protection grade. It is a serial port networking server that enables serial port devices to have networking capabilities immediately, and it can centrally manage scattered serial devices and hosts through the network. This product supports 1 channel of RS-232/RS-422/RS-485 to 1 channel of Fast Ethernet and can be installed in 35mm rail or wall mount to meet the needs of different application sites.


The serial port server supports a variety of network protocols, such as TCP, UDP, ARP, ICMP, HTTP, DNS, DHCP, and SNMP protocols. It has complete management functions, and supports access control, rapid configuration, online upgrade, etc. Each serial port supports 4 channels TCP or UDP session connection, and it supports Modbus TCP, TCP Server, TCP Client, UDP Server, UDP Client, and other working modes. It supports WEB access mode. In addition, the management and configuration tool based on the Windows platform can guide users to manage and configure the device, and realize the immediate networking of serial devices by simple settings. The interface design of the network management system is friendly, the operation is simple and convenient, and it can bring you a good user experience.


The hardware adopts fanless, low power consumption, wide temperature, and wide voltage design. It has passed strict tests in line with industry standards and can adapt to industrial field environments with strict EMC requirements. It can be widely used in PLC control and management, building automation, healthcare automation systems, measuring instruments and environmental dynamic monitoring systems, etc.


It can be used in many embedded network control applications:

– Industrial automation production

– Security access control: network access control, alarm equipment, infrared detection alarm, remote card reader

– Smart home equipment: smart home gateway, smart socket, smart switch

– Network IO Controller: Industrial Remote IO Input, Remote Relay Control

– Building intelligence and energy monitoring

– Medical monitoring equipment
