8 Ports RS232 RS485 RS422 to Ethernet TCP/IP Serial Device Server Modbus Gateway Converter

This industrial 8-port serial to Ethernet converter acts as a multi-channel serial device server and Modbus protocol gateway, seamlessly converting RS232, RS485 and RS422 serial signals to standard TCP/IP Ethernet network data. Each serial port supports flexible software switching among three serial standards to connect various industrial serial sensors, PLCs, meters and legacy serial equipment.

It realizes bidirectional transparent data transmission between serial devices and LAN/remote network, with built-in Modbus gateway function to achieve mutual conversion between Modbus RTU serial protocol and Modbus TCP industrial Ethernet protocol. Supporting multiple network transmission modes including TCP Server, TCP Client and UDP, it comes with virtual COM driver for PC remote serial access, and supports DHCP, DNS, heartbeat and custom registration packet functions for stable long-distance data communication.

Equipped with 10/100M self-adaptive RJ45 Ethernet port, the metal housing device supports wide-range DC power input and DIN rail mounting, suitable for factory automation, intelligent monitoring, energy management, access control and other industrial IoT scenarios. Users can complete parameter configuration via built-in web page, Telnet or dedicated management tool, supporting remote firmware upgrade and automatic reconnection to ensure uninterrupted industrial data transmission.
