The Waveshare RS232 RS485 to RJ45 Ethernet Serial Server, Dual Channel Independent Ethernet Ports is an industrial-grade device designed for seamless data transmission and integration in complex environments. It features dual independent serial channels, RS232 and RS485, which can operate simultaneously without interference, connected through a single Ethernet cable. This device serves multiple functions, including acting as a serial server, Modbus gateway, and MQTT gateway, facilitating data acquisition and IoT gateway applications.

Housed in a durable rail-mount metal case, the server supports bi-directional transparent data transmission between RS232 and RS485 to Ethernet. It includes two Ethernet ports, one of which can function as a network switch or for cascading, with optional PoE support. The device is equipped with power and signal isolation, ensuring stable and secure operations. It is compliant with IEEE 802.3af standards and features a 10/100M auto-negotiation RJ45 connector with 2 KV surge protection.

The server supports various communication modes, including TCP server, TCP client, and UDP multicast, and operates efficiently in extreme temperatures and humidity levels. It also offers Modbus networking upgrades, MQTT/JSON to Modbus conversion, and multiple configuration methods. The aluminum alloy enclosure provides robustness and a refined finish, making it suitable for industrial applications such as safety and security IoT and intelligent instrument monitoring.
