Waveshare 24963 2-Channel RS485 to PoE Ethernet Serial Server

Connect to the device via its default IP address using a web browser. Navigate to the configuration page and set the operating mode to 'Modbus Gateway'. Define the serial parameters (baud rate, parity) for each RS485 channel to match your slave devices. Then, map the Modbus RTU slave addresses to TCP connections. The gateway will transparently convert RTU frames to TCP packets, allowing SCADA software to communicate with serial devices over the network. Save the configuration and restart the unit.

The server offers three power methods. First, Power over Ethernet (PoE) via either RJ45 port per IEEE 802.3af standard. Second, a DC jack accepting 6V to 40V input. Third, a screw terminal block for direct wiring of a DC source within the same voltage range. The internal isolation circuitry protects the logic board from power line surges. For simplest deployment, use a PoE switch or injector. Ensure your power source can provide sufficient current for both the module and any peripherals on the RS485 bus.

Yes, each RS485 channel is fully independent, including its configuration. You can set Channel A to 9600 baud, 8-N-1 for a sensor network, and Channel B to 115200 baud, 8-E-1 for a high-speed controller, simultaneously. The web-based configuration interface allows separate settings for baud rate, data bits, parity, and stop bits per channel. This independence is crucial for integrating legacy equipment with different serial standards into a unified Ethernet-based monitoring system without requiring additional hardware converters.
