Unmatched Reliability and Broad Compatibility

Engineered for maximum stability, this adapter incorporates a high-quality FTDI chipset. This industry-leading component ensures broad operating system compatibility, including support for Windows®, macOS, and Linux, guaranteeing a seamless integration into virtually any work environment. The FTDI chipset is renowned for its reliable drivers and consistent performance, preventing the connection dropouts and system conflicts often associated with lesser adapters.

Effortless Configuration and Ultimate Convenience

Experience true plug-and-play functionality. The adapter´s intelligent COM Port Retention feature automatically reassigns the same COM port value to the port if the cable is disconnected and reconnected to the host computer, or if the system is rebooted. This eliminates the hassle of reconfiguring your software each time, saving valuable time and frustration, especially in mobile or field applications. Further simplifying setup, the unit is entirely USB-powered, drawing power directly from the host USB-A port and removing the need for a cumbersome external power adapter. Onboard dipswitches provide tactile, straightforward control for switching between RS422 (4-wire) and RS485 (2-wire) modes and managing termination.
