4GE (3xLAN+1xWan) 8 channel Serial Server (with WEB, SNMP)

This industrial rail serial server is IP40 protection grade. It is a serial network server that allows serial devices to immediately have networking capabilities. It can centrally manage scattered serial devices, hosts, etc. through the network. This product supports 1-8 RS-232/RS-422/RS-485 to 4 Gigabit Ethernet (3*Lan+1*Wan), meeting the needs of dual IP and dual MAC addresses/multi-network management or network routing/backup, and can be installed in 35mm rail and wall mounting.

The serial server supports a variety of network protocols, such as TCP, UDP, ARP, ICMP, HTTP, DNS, DHCP, SNMP, Telnet, SSH, MQTT and other protocols; it has complete management functions, supports access control, fast configuration, online upgrades, etc.; each serial port supports 4 TCP or UDP session connections, supports Modbus TCP, TCP Server, TCP Server, TCP Client, UDP Server, UDP Client, Modbus to MQTT and other working modes; supports WEB access. In addition, the Windows-based management configuration tool provided with the system can connect serial devices to the Internet immediately through simple settings. The network management system has a user-friendly interface design and is easy to operate, which can bring you a good user experience.

The hardware adopts a fanless, low-power, wide temperature and voltage design. It has passed strict tests in accordance 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 power monitoring systems.

It can be used in many embedded network control application products:

– Industrial automation production
