USB 2.0 to RS232 DB9 Serial Converter Cable with Prolific PL2303 Chipset, USB to 9-Pin DB9 COM Port Serial Adapter

This USB 2.0 to RS232 DB9 serial adapter cable is equipped with the Prolific PL2303 control chip, which converts the common USB interface into a classic 9-pin DB9 RS232 serial port. It generates a virtual COM port on your computer, perfectly solving the issue that most modern laptops and desktops remove the native serial port.

The PL2303 chip delivers outstanding anti-interference capability and consistent data transmission performance, greatly reducing packet loss and communication interruption during long-time debugging work. This serial cable complies with standard RS232 electrical specifications, suitable for network switches, routers, PLC controllers, testing instruments, barcode scanners and various industrial serial peripherals.

Both terminals adopt molded connector housing together with reinforced strain relief design, which protects internal wires from fracture caused by repeated twisting, pulling and vibration. High-quality shielded wire minimizes electromagnetic interference and guarantees reliable signal output in complex working environments.

Drivers for multiple operating systems are available for the PL2303 chip. After finishing driver installation, the cable can be identified smoothly for serial data transmission. It is an indispensable debugging accessory for equipment maintenance staff, automation engineers and electronic DIY hobbyists.

Important Reminders

1. Official PL2303 driver installation is required. The cable may not work normally without correct drivers.
2. This cable supports RS232 level signals. It is incompatible with TTL serial modules, please check before purchase.
3. Keep the cable away from high temperature, moisture and strong electromagnetic fields.
4. Avoid violent pulling when the cable is transmitting data to prevent communication failure.
