SIXNET ET-GT-485-1 Industrial Ethernet to Serial RS-485 Modbus Gateway

The SIXNET ET-GT-485-1 is an industrial Ethernet to serial gateway designed to seamlessly integrate Modbus, Sixnet, or other serial devices into an Ethernet network. This gateway acts as a bridge, providing Ethernet connectivity to existing serial-based systems without the need to replace hardware. It supports Modbus RTU protocol and operates reliably in harsh industrial environments, making it an ideal solution for integrating legacy systems into modern Ethernet-based networks.
