The power supply and signal are fully isolated, providing galvanic isolation between the USB host and the RS485/RS422 side for stronger antiinterference and enhanced protection of equipment. USB to RS485/RS422 converter lets PC users connect RS485 or RS422 devices to systems that use USB interfaces, expanding host capability without added adapters. Noninvasive installation: attach the converter to a PC without opening the chassis or powering down to install an expansion hub or extra port. Port addition on demand: with the converter, you instantly gain one speed RS485 or RS422 port for reliable multidevice communication. Compatibility and performance: designed for use with standard USB ports and RS485/RS422 devices, offering steady data transmission with isolation to help maintain signal integrity. Use scenarios Industrial automation and control: connect PLCs, motor drives, sensors, and remote I/O devices to a PC for monitoring, logging, or control software without expanding the internal hardware. Data acquisition and testing: bring RS485/RS422 measurement instruments, DAQ devices, or test equipment online via USB for quick data collection and analysis. Building management and security systems: integrate energy meters, access control panels, environmental sensors, and other RS485/RS422 devices with a USBenabled workstation for centralized management.
