Overview

The TEC105T series Layer 2 managed embedded industrial Ethernet switch module is a 5-port 100M embedded core board with 2 serial ports. It provides 5 configurable 100M optical/electrical ports, allowing the Ethernet interface type to be freely configured via module pins. It offers 2-channel serial-to-Ethernet serial server functionality. Users can customize the interface board design to meet the requirements of different application sites.It can be widely used in industrial fields such as rail transit, new energy, smart grid, smart manufacturing, smart city, and smart mining.
