USB 2.0 to DB9 serial adapter

This 61-inch cable converts a USB 2.0 Type-A port into a male DB9 RS232 connection using an FTDI chipset. It targets technicians and hobbyists who need to link legacy industrial equipment, such as CNC machines, engraving tools, or access-control panels, to modern laptops or desktops lacking native serial ports.

Replaces built-in or PCI serial ports

The adapter upgrades systems that have lost native DB9 headers or where expansion slots are unavailable, and the jump is worth it when software expects a genuine COM port with FTDI driver support across Windows 11 down to 98, Mac OS 8.6+, and Linux.

Driver-first installation

Plug-in detection occurs after the FT232 driver is installed from the official FTDI site; skipping this step is the most common reason the cable appears dead. The oxygen-free copper core and PVC jacket tolerate repeated bending, but the DB9 gender is fixed male, so a gender changer is required for female-to-female links.

Questions about this item

How long is the cable and what type of USB connector does it have?

The cable measures 61 inches and terminates in a standard Type-A USB plug that connects to the host computer.

Which driver must be installed before the adapter will appear as a COM port?

The adapter uses an FTDI chipset, so the FT232 driver must be downloaded from the official FTDI site and installed before first use.

How does the oxygen-free copper core affect the cable's expected service life?

The manufacturer states the tin-plated oxygen-free copper core gives the cable a service life 50 times longer than ordinary products.
