USB To RS232 Converter Cable

USB To RS232 Converter Cable

The USB-to-RS-232 converter cable provides a bridge between modern USB ports and legacy RS-232 serial devices. It enables a computer without a built-in serial (DB9) port to communicate with older peripherals such as modems, barcode scanners, industrial controllers, and more. The conversion is done via integrated electronics in the cable, making it appear to the host computer as a standard serial port once installed.

This cable is designed for ease of use: simply plug the USB-A end into a PC and the DB9 male connector into your RS-232 device. Once connected, the built-in chipset (such as PL2303 or FTDI) handles serial-to-USB data translation, managing the voltage level shifting and protocol conversion. Because the cable is bus-powered, there’s no need for an external power supply, making installation clean and portable.

In operation, the adapter maintains reliable serial communication at a wide range of baud rates, enabling legacy hardware to work seamlessly with newer computers. Whether you’re working in a lab, industrial environment, or running point-of-sale equipment, the converter cable offers a cost-effective and practical solution for integrating RS-232 systems into modern computing environments. Its durable design ensures stable connectivity even under extended use.
