USB to RS232 Serial Cable

The BFKK cable converts a standard USB port into a DB9 serial connection using the Prolific PL2303 chipset. It targets technicians and engineers who need to configure legacy industrial hardware, networking gear or point-of-sale equipment from a modern laptop. The 3.3-foot length suits bench work and rack-side access without excess slack.

Build and connectivity

A tinned copper conductor with triple shielding protects signal integrity at the rated 1Mbps transfer rate. The male DB9 connector mates directly with modems, PLC controllers, barcode scanners and label printers, while the USB-A plug draws bus power so no external adapter is needed. Driver installation from the supplier website is required before first use on Windows 11, 10, 8.1, 8, 7, Linux or Mac OS.

Bundled value

The package supplies a single 3.3-foot cable backed by a 24-month warranty and lifetime customer support. Included driver access enables immediate compatibility with the listed operating systems. The adapter does not support cutting plotters or SCM devices, so buyers needing those specific peripherals must seek an alternative solution.

Questions about this item

What USB standard does this PL2303 cable use and what throughput does it cap at?

It uses a USB port rated at 1 Mbps, so the serial link cannot exceed that speed in practice.

What physical clearance and connector gender does the DB9 end require?

The cable ends in a male DB9 plug, so the mating port must be a female DB9 with enough rear clearance for the 3.3 ft cable bend radius.

Which driver-install step do users most often skip on Windows 11?

They plug the cable in before downloading the PL2303 driver from the CableCreation site, so the adapter stays unrecognised until the driver is installed first.
