USB 2.0 to RS232 DB9 Adapter

This ORVIX adapter bridges a USB 2.0 port to a male DB9 serial connector using the PL2303 chipset. It targets technicians and hobbyists who need to link legacy serial equipment such as modems, label writers, CNC controllers, POS printers or barcode scanners to modern computers lacking a native COM port.

Check OS and device compatibility

The adapter supports Windows 11, 10, 8.1, 8, 7, Linux and Mac OS, but the supplier notes it is not compatible with cutting plotters or SCM equipment. Verify that your serial device uses a standard DB9 pinout and does not require proprietary signalling before ordering.

Gold-plated connectors and USB power

Gold-plated contacts aim to maintain signal integrity at the rated 1 Mbps transfer rate. The unit draws power directly from the USB port, so no external supply is needed. Drivers are available for download from the manufacturer's website to complete the setup.

Questions about this item

What comes in the box and do I need any extra cables?

The adapter ships with a gold-plated DB9 male connector on a USB 2.0 lead; no separate cable or power supply is required because it draws power from the USB port.

Which chipset version should I pick for Windows 11?

The unit uses the Prolific PL2303 chipset, which the manufacturer lists as compatible with Windows 11, 10, 8.1, 8, 7, Linux and Mac OS.

What does the 1 Mbps transfer rate mean when I plug it into a CNC controller?

The USB 2.0 port is rated at 1 Mbps, so serial data moves at up to that speed — fast enough for most modems, label writers, POS terminals and PLCs.
