2 Port RS232/422/485 Serial to Ethernet Converter

View : 987
Type : Serial To Ethernet Converter
Description :

The RS232/422/485 Serial to Ethernet Converter supports 1-2 channels of RS-232/RS-422/RS-485 to 1 channel of 100M Ethernet comb port (providing 1 channel of 100m electric port or 1 channel of 100m optical port).


This serial to ethernet converter is an industrial din rail type serial port server with IP40 protection grade.

It is a serial port networking server that enables the serial port devices to immediately have networking capability.

It can centrally manage scattered serial devices and hosts through the network. The product supports 2 channels of RS-232/RS-422/RS-485 to 1 channel of 100M Ethernet comb port (providing 1 channel of 100M electric port or 1 channel of 100M optical port). It can be installed in 35mm rail and wall-mounted modes, which can 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 perfect management functions and supports access control, rapid configuration, online upgrade, etc. Each serial port supports 4 TCP or UDP session connections, and supports multiple working modes such as TCP server, TCP client, UDP server, UDP client, etc. It supports web access mode. In addition, the management configuration tool based on the Windows platform can guide users to manage and configure devices, and realize the immediate networking of serial port devices by simple settings. The network management system has a friendly interface design, simple and convenient operation, and can bring you a good user experience.


The hardware is designed with no fan, low power consumption, wide temperature, and wide voltage. It has passed strict testing in line with industry standards and can adapt to the industrial field environment with severe requirements for EMC. It can be widely used in PLC control and management, building automation, medical care automation system, measuring instruments, and environmental power monitoring system.


This RS232/422/485 serial to ethernet converter can be used in many embedded network control application products:

-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
