Bidirectional Half Duplex Serial Adapter USB to RS485 Serial Port Converter Adapter Cable ABS Blue Auto Direction Switch TXD RXD Indicator Pure Hardware (USB to RS485)
Industrial-Grade Circuit Protection： This adapter incorporates TVS suppression, ESD protection, and sur ge protection circuits. It also features short-circuit protection on both signal lines and power rails, designed to prevent damage in case of accidental shorts. This built-in safety helps enhance connection reliability in demanding industrial electrical environments
Long-Distance & Stable Data Transmission： Leveraging the RS485 standard, this converter supports transmission distances up to approximately 1200 meters (at 9600bps) and configurable baud rates as high as 921600bps. Its noise resistance makes it suitable for long-range, multi-drop networks in applications like building automation, environmental monitoring, and distributed data acquisition systems
Broad OS Compatibility & Plug-and-Play： Compatible with a wide range of operating systems including Windo ws (98/XP/7/10/11), Linux, and M ac OS. The USB to RS485 converter supports hot-plug via its USB interface and typically requires no additional drivers for automatic detection, simplifying connections between modern computers and legacy industrial equipment
Automatic Data Direction Control： Features adaptive direction control technology. It automatically manages data flow direction without requiring R TS/DTR handshake signals or manual jumper settings. This ensures broad compatibility with most existing RS485 communication protocols and software, offering a plug-and-play setup for easy integration
LED Indicators & External Power Option： Equipped with TXD and RXD LED lights for clear visual feedback on data transmission status. As a pure hardware serial adapter, it is not limited by specific protocols. Includes an external 5V power terminal and a built-in fu se to support more stable operation when powering bus-connected devices or larger networks
