The EthLinx Pro Duo is a high-performance gateway engineered for the most demanding tasks. It connects your TCP/IP applications to two independent, fully isolated RS-485 buses at lightning speed. Your computer (Windows/UNIX) instantly recognizes it as a network card—no drivers required. Configure and manage everything conveniently via the embedded web server or our Python API.
Key Features
Superior Galvanic Isolation: Two fully isolated channels (>1.5kV) guarantee maximum safety and signal integrity in harsh industrial environments.
Instant Driverless Connection: Thanks to native support in modern operating systems (RNDIS/CDC-ECM), the device is ready to use the moment you plug it in.
Intuitive Web Management: Access all parameters, detailed real-time statistics, and device info from any web browser.
Flexible Software Configuration: Effortlessly adjust baud rate, parity, 120Ω termination, or bus bias with just a few clicks.
Advanced Multi-Client Access: Each channel supports up to four simultaneous TCP connections, ideal for complex multi-master systems or advanced diagnostics.
Extreme Speed & Performance: With support for up to 15 MBd, a USB 2.0 High Speed (480 Mbit) interface, and large 16kB buffers, it handles the most intensive data streams with ease.
Detailed Status LEDs: Multi-color LEDs give you immediate visual feedback on TCP status, data transfer, and any bus errors.
Ready for Automation: A simple Python API and a script-friendly HTTP interface (GET/POST) allow for seamless integration into your workflows.
Rugged & Compact Design: Its durable metal case (80x50 mm) with industrial-grade connectors is engineered for maximum reliability.
