How It Works
The converter connects to a computer through the USB interface and converts USB serial data into RS422 or RS485 differential communication signals. Devices are connected through the screw terminals, allowing reliable long-distance communication with PLCs, industrial controllers, sensors, energy meters, and Modbus RTU devices. Once the appropriate driver is installed (if required), the converter appears as a virtual COM port for communication software.
