The 1-Port RS232/RS485 Serial to Ethernet Server is an industrial-grade networking solution designed to connect legacy serial devices to modern Ethernet networks quickly and reliably. It enables transparent data transmission between RS232 or RS485 equipment and TCP/IP networks, making it ideal for industrial automation, building management systems, and remote monitoring applications.
Built for industrial environments, this serial device server features a rugged, fanless design with wide temperature tolerance and EMC protection. It supports multiple communication modes including TCP Server, TCP Client, UDP, and Modbus TCP, allowing seamless integration with PLCs, HMIs, sensors, meters, and other serial devices.
With flexible mounting options, wide voltage power input, and advanced network protocols, this RS232/RS485 to Ethernet converter ensures stable, secure, and long-term operation in demanding industrial settings. Two TCP ports are available, one for RS232 and one for RS485, so two data streams can be used independently.
