USB 2.0 to RS232 DB9 Male Serial Converter Adapter Cable, PL2303 Dual Chip USBtoCOM Serial Cable for PLC, Router, Switch, POS, Industrial Equipment Debugging & Serial Data Communication

This USB 2.0 to RS232 DB9 serial adapter cable uses PL2303 dualchip architecture to convert USB signals into standard RS232 serial communication signals. It solves the problem that modern laptops and desktops no longer have native DB9 COM ports, allowing users to connect and configure traditional serial devices.

Integrated electrostatic discharge protection enhances stability under complex field conditions, reducing communication dropouts caused by static and electromagnetic interference. Fully compliant with USB 2.0 specification, backward compatible with USB1.1. The molded DB9 male connector ensures tight connection without loose signal during frequent debugging operations.

Widely applied to industrial PLC programming, router & switch console debugging, POS cash registers, serial scanners, accesscontrol equipment and serial data acquisition modules. Driver installation is required to generate virtual COM port. Please select the matching PL2303 driver according to your operating system. An indispensable practical tool for electronic maintenance, network debugging and industrialsite equipment commissioning.
