8-Port Serial to Ethernet Converter RS232 RS485 RS422 TCP/IP Device Server Modbus RTU to TCP Gateway

This 8-port industrial serial device server converts multi-channel RS232, RS485 and RS422 serial data to standard TCP/IP Ethernet signals, enabling centralized networking and remote management of dozens of traditional serial devices. Each of the 8 serial ports works independently without signal interference, supporting TCP Server/Client, UDP and transparent transmission modes. It features built-in Modbus gateway function to seamlessly communicate with PLC, power meters and sensing equipment from mainstream automation brands. Equipped with adaptive 10/100Mbps LAN port and complete surge isolation circuit, the converter effectively resists electromagnetic interference in harsh factory sites.

Users can configure communication parameters via embedded web page or virtual serial port tool, and remotely update firmware without powering off the device. Ideal for industrial automation, power monitoring, intelligent building, environmental data collection and multi-device centralized control projects.
