USB to RS232 DB9 adapter

This USB to RS232 DB9 female cable adds a legacy COM port to any laptop or desktop that lacks one. It uses an FTDI FT232 chipset and a 9-wire pinout to provide reliable serial connectivity. The adapter draws power directly from the USB port so no external supply is needed. It suits engineers and technicians maintaining older industrial or networking equipment.

Six-foot cable reach and OS support

The six-foot length gives enough slack to reach devices mounted in racks or panels without strain. USB 2.0 signalling and the FTDI driver stack support Windows 11, 10, 8, 7, Mac OS 8 or higher and Linux 2.4.0 or later. Performance is limited to standard RS232 signalling rates and the cable cannot replace high-speed or multi-port serial cards.

FTDI FT232 chipset

The built-in FT232 processor chip handles the USB-to-serial conversion and is widely recognised for stable driver operation across supported platforms. Buyers who need galvanic isolation, TTL voltage levels or multiple simultaneous ports should look for a different class of adapter.

Questions about this item

Will the 6 ft FTDI cable work with the serial device I already own that uses a DB9 port?

The cable provides a standard 9-pin DB9 female connector with pins 2 RXD, 3 TXD and 5 GND, matching the common RS232 pinout used by most legacy serial equipment.

How can I verify the FT232 chipset is communicating correctly after I plug it in?

Open Device Manager on Windows or run `ls /dev/ttyUSB*` on Linux; the adapter should appear as a new COM or ttyUSB port without error codes.

Does the package include any drivers or null-modem adapters, or must I source them separately?

The adapter is USB-powered and uses the FTDI chipset supported natively by Windows 11 10 8 7, Mac OS 8 or higher and Linux 2.4.0; no external power supply or additional cables are required.
