USB 2.0 to RS232 DB9 Serial Cable Adapter with Prolific PL2303 Chip, USB to 9 Pin COM Port Serial Converter Cable, Support Industrial Equipment, PLC, Router Serial Debugging

This USB 2.0 to RS232 DB9 serial adapter cable adopts the industry-standard Prolific PL2303 controller chip, offering reliable conversion between USB signal and RS232 serial signal. It creates a virtual COM port on your computer, allowing modern laptops without native serial ports to connect traditional RS232 devices.

It works perfectly for industrial PLC debugging, network router & switch console configuration, serial POS equipment, serial sensors, barcode scanners and CNC equipment. The cable features effective shielding to reduce electromagnetic interference, ensuring stable serial data transmission even in complex industrial environments.

Compatible with Windows, macOS and Linux operating systems. Corresponding driver needs to be installed before use to recognize the virtual COM port. High-quality copper conductors and sturdy DB9 connector prevent loose connection during long-time continuous operation.

Great replacement for old PCI serial expansion cards. Compact wired design is convenient for field debugging, equipment maintenance and workshop use.

Important Note: Driver installation is required. Please confirm your system version to match the correct PL2303 driver. This cable follows RS232 standard protocol; verify device pin definition before connection.
