10FT USB to DB9 Serial Adapter

This 10FT cable converts a USB port to a male DB9 serial connector using an FTDI FT232RL chipset. It draws power directly from the USB connection, removing the need for an external power supply. The adapter is recognised as a standard COM port by the operating system. It supports a 9-wire pinout covering pins 1 through 9.

Suits legacy equipment with male DB9 ports

The cable is designed for devices that present a male DB9 serial interface requiring a female DB9 connection. It is not suitable for equipment that uses a female DB9 port or a 15-pin VGA connector. Buyers needing to connect to a female DB9 socket should look at a different gender configuration. The product is built specifically for RS232 serial communication, not video signals.

FTDI FT232RL chipset with broad OS support

The FT232RL chipset provides driver compatibility across Windows 11, 10, 8, 7, Mac OS 8 or higher, and Linux kernel 2.4.0 and later. This single component determines whether the adapter will enumerate correctly on the host system. Verify the target operating system appears in this supported list before purchase.

Questions about this item

Will the 10FT cable reach legacy equipment mounted in a deep rack?

The 10FT length gives extra reach for rack-mounted or floor-standing serial devices without needing an extension cable.

How can I confirm the FT232RL chipset is recognised by Windows 11 after driver installation?

Open Device Manager and verify the adapter appears under Ports (COM & LPT) as a USB Serial Port with an assigned COM number.

Does the package include a driver disc or must I download the FT232 driver separately?

No disc is included; the supplier directs you to download the driver from the official FT232 website before first use.
