Purpose and Compatibility
This USB to RS232 serial cable connects DB9 devices such as modems, PLC controllers, barcode scanners and POS equipment to a USB port. It uses the Prolific PL2303 chipset and supports Windows 11, 10, 8.1, 8, 7, Linux and Mac OS. The 3.3FT length suits bench or rack setups. Buyers who need a Cutting Plotter or SCM connection should choose a different adapter.
Interface Limits
The link runs at a 1Mbps data transfer rate over the USB interface. Driver installation from the supplier website is required before the cable will function. The connector is a serial DB9 male plug, not a VGA port. No external power adapter is needed because the cable draws power from the USB bus.
Installation Notes
Install the driver first, then plug the cable into the USB port and attach the DB9 device. The tinned copper conductor and triple shielding help maintain signal integrity. If the device is not recognised, reinstall the driver and check the COM port assignment in the operating system. The package includes one cable.

Questions about this item
Which cable length should I choose for a standard desk setup?
The 3.3 ft length is the only option listed and is suited for typical desktop connections.
What does the 1 Mbps USB transfer rate mean when the adapter is in use?
It sets the maximum serial data throughput at 1 Mbps, so connected RS‑232 devices will not exceed that speed.
Does the PL2303 chipset limit which operating systems can be used?
The PL2303 supports Windows 11, 10, 8.1, 8, 7, Linux and Mac OS, so those platforms are covered.
