TG103H Series
EtherWAN’s TG103H is a hardened unmanaged Gigabit Ethernet switching platform, designed for easy deployment in harsh environments with limited space. Its operating temperature is ranging from - 40°F to 167°F. It is a low-cost, easy-to-use device that combines essential industrial Ethernet networking functionality with rugged performance.
This versatile switch features full/half-duplex auto-negotiation and auto MDI/MDIX operation, allowing for convenient connection of a variety of network devices. QoS (Quality of Service) support allows for traffic prioritization and effective management of resources. A built-in watchdog feature supports the TG103H as an intelligent device to prevent packet loss from powered devices in the network. The feature can be enabled per port via DIP switch to enhance the feature flexibility.
