The Waveshare 2-Ch RS485 to RJ45 Ethernet Serial Server, Dual Channel RS485 Independent Operation, Dual Ethernet Ports (PoE) is an advanced device designed for industrial environments, serving as a versatile data acquisitor and IoT gateway. It integrates multiple functionalities, including a serial server, Modbus gateway, MQTT gateway, and network switch, all within a compact and easy-to-install module. The device supports dual RS485 channels and dual Ethernet ports, with the option for Power over Ethernet (PoE), ensuring seamless and independent operation of each channel.

This module facilitates bi-directional transparent data transmission between RS485 and Ethernet, offering flexible power supply options through a DC port, screw terminal, or PoE, accommodating a wide voltage range. It supports Ethernet port cascading, allowing for extended communication networks, with each module requiring individual power. The device is engineered with industrial-grade rail support, ensuring durability and ease of installation.

The server supports various communication modes, including TCP Server, TCP Client, UDP Multicast, and UDP Mode, with each channel capable of operating these functions independently. It enables protocol conversion between MQTT/JSON and Modbus, allowing devices to upload serial data to an MQTT server or connect to data acquisition instruments for JSON data conversion. The module also supports multi-host roll-polling, user-defined heartbeat packets, and NTP protocol for network time synchronization.

Constructed with an aluminium alloy enclosure, the device offers robust protection features, including power and signal isolation, surge protection, and a resettable fuse, ensuring safe and stable operation in demanding environments.
