M12 interface 8*Serial Ports + 2*CAN Servers

This M12 serial port server is IP68 protection grade. It is a serial port networking server that allows serial port 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+2 CAN to 2 100M Ethernet ports, meeting the needs of dual IP and dual MAC addresses/multi-network management or network backup, and adopts wall-mounted installation.

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, 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 management and configuration tool based on the Windows platform provided in conjunction with the serial port device can be connected to the network 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 fanless, low power consumption, 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, medical and health automation systems, measuring instruments and environmental power monitoring systems.
