Unlock Your Serial Devices with Effortless Network Connectivity
The EthLinx Pro is a high-performance gateway that bridges your TCP/IP software applications directly to a fully isolated RS-485 serial bus. It appears as a standard network card on your Windows or UNIX system, requiring no custom drivers for a true plug-and-play experience. Configure, monitor, and manage your serial communication with unmatched flexibility through its embedded web server or our Python API.
Key Features
- Dual Isolated RS-485 Channels: Galvanically isolated channel (>1.5kV) ensures robust and safe operation in demanding environments.
- Driverless USB Network: Uses standard USB RNDIS or CDC-ECM device classes, appearing as a network adapter on any modern OS for instant connectivity.
- Intuitive Web Management: Configure all serial parameters, monitor bus statistics, and view device info from any web browser via its built-in HTTP server. The UI is available in multiple languages.
- Advanced Software Configuration: Easily set baud rates, parity, stop bits, and enable/disable 120Ω termination or idle-bus biasing via the web interface.
- Multi-Client Access: Each channel supports up to four simultaneous TCP connections, allowing for multi-master access, traffic spying, or logging without disrupting the primary application.
- High-Speed Performance: Supports baud rates from 4800 Bd up to 15M Bd, powered by a USB 2.0 High Speed (480Mbit) interface and large 16kB communication buffers.
- Detailed Status Indicators: Multi-color LEDs provide instant visual feedback on TCP connection status, data transfer, and bus errors.
- Scripting and Automation Friendly: Features a simple Python API and a script-friendly HTTP interface (GET/POST) for full device control and automation.
- Rugged & Compact Design: Housed in a durable metal case (80x50 mm) with industrial-grade 3.5mm terminal connectors. The case is grounded via the USB Type-C shield for enhanced ESD protection.
