4 Port Serial Device Server | WEB and SNMP Management

View : 887
Type : serial server
Description :

This product supports 1-4 channels of RS232/RS422/RS485 to 1 channel of 100M Ethernet Comb port (providing 1 channel of 100M electrical port or 1 channel of 100M optical port).


This product is an industrial rail-type serial port server with IP40-rated, which is a serial port networking server that enables serial port devices to have networking capabilities immediately and can centrally manage scattered serial devices, hosts, etc. by the network. This product supports 1-4 channels of RS-232/RS-422/RS-485 to 1 channel of 100M Ethernet Comb port (providing 1 channel of 100M electrical port or 1 channel of 100M optical port), can use 35mm rail type and Wall-mounted installation 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, supports access control, quick configuration, online upgrade, etc.; each serial port supports 4-way TCP Or UDP session connection, support Modbus TCP, TCP Server, TCP Client, UDP Server, UDP Client, and other working modes; support WEB access mode. In addition, the provided management and configuration tool based on the Windows platform can guide users to manage and configure the device step by step, and realize the immediate networking of serial devices through 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, and healthcare automation. systems, measuring instruments and environmental dynamic monitoring systems, etc.


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.
