Transmission distance and baud rate Transmission distance up to 1200 meters. In testing, performance was observed at 9600 bps. Supports baud rates up to 921600. This provides a much higher data transfer capability than common 115200 baud. Enables faster and longer range pointtopoint communication with compatible devices. Flexible switching and compatibility Automatic data direction control. The device identifies and manages the transmission direction without the need for handshake signals. No RTS, DTR, or other control signals required. No jumper settings needed to switch modes. Designed to maintain compatibility with existing communication software and interface hardware. Broad OS support and hot plug Hotswappable USB interface for easy replacement and upgrades. Supports multiple operating systems including Windows 98, Windows CE, Windows 2000, Windows 2003, Windows 2008, Windows XP, Windows Vista, Windows 7, Windows 10, Linux, and OS X. Industrial protection TVS transient suppression protection. ESD protection. Surge protection. AB signal line short circuit protection and power short circuit protection. Short circuits do not cause burning. Applications Industrial automation and remote device networking: extend your PC or controller connection to remote instruments or controllers up to 1.2 km away, enabling reliable data logging and control in factory environments. Legacy system integration: connect older Windows or Linux machines to newer peripherals without modifying existing software or interface hardware, while maintaining data transfer speeds. Field maintenance and testing: use in temporary setups or service scenarios where hotplug capability and robust protection reduce downtime and equipment risk.
