EthLinx™ Data Converters
Discover the modern way of serial communication. Use our signature USB network connectivity for your serial industrial devices. Explore the unique data converters EthLinx. These innovative data converters act as standard USB network adapters (RNDIS/CDC-ECM device classes offered), eliminating the driver issue while providing robust, galvanically isolated RS-485 or a simple overvoltage protected UART communication directly via convenient TCP Sockets with multi-client access. Configure baud rates, parity, and other settings effortlessly through an intuitive web-based interface, accessible from any browser on your computer.
EthLinx: Convenient TCP Socket data transfers to your serial interfaces via USB
Forget the VCOM Port limitations, generic serial port drivers and compatibility headaches forever. EthLinx devices present themselves as standard network interfaces to your Windows, Linux, or macOS computer. This modern approach simplifies integration, allowing you to communicate with your RS-485 or UART devices using standard TCP/IP protocols over a virtual Ethernet connection, making setup faster and more reliable across different platforms.
The EthLinx line offers various performance, interface types and channel count options to precisely match your project requirements. Whether you need straightforward single-device communication or high-throughput connections for multiple data streams, there’s an EthLinx converter built for the task:
EthLinx works fully local, it uses NO INTERNET CONNECTION
The Key Advantage: USB Network vs. Legacy VCOM
The EthLinx Approach (TCP/IP over USB)
- Multi-Client Access: Multiple applications can access the shared serial bus simultaneously via standard TCP sockets.
- Truly Driverless: Zero driver installation required; uses native OS network interfaces (RNDIS/CDC-ECM) for true Plug & Play.
- Web-Based Setup: Effortless configuration through an intuitive, built-in Web UI accessible from any modern browser.
Standard VCOM Devices (Virtual COM)
- Single-App Lockout: The COM port is locked to a single application; sharing the bus is not possible.
- Driver Headaches: Requires manual installation of proprietary drivers (like FTDI or CH340) which often cause OS conflicts.
- Clunky Configuration: Setup often relies on physical DIP switches, or outdated third-party software.
