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 by the network. This product supports 8 channels of RS-232/RS-422/RS-485 to 2 channels of 100M Ethernet, meeting the requirements of dual IP and dual MAC addresses/multi-network management or network backup, and can adopt 35mm railed and wall-mounted installation methods. The serial port 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, quick configuration, online upgrade, 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; and it supports WEB access mode. In addition, the management and configuration tool based on the Windows platform is provided, and the serial device can be connected to the Internet immediately by simple settings. The interface design of the network management system is friendly, and the operation is simple and convenient, which 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.
