Serial adapter for legacy RS-232 devices

The Vszerda RS232 DB9 Female to USB 2.0 A Female converter adds a serial port to a PC that lacks one, using an FTDI chipset for reliable communication. It connects a standard DB9 device to a USB Type-A port and draws power directly from the bus. The cable length is 25cm, making it suitable for internal or tight external routing. Compatible with Windows 10, 8, 7, Mac OS 8 or higher, and Linux 2.4.0 and later.

Ideal for industrial or lab equipment owners

Engineers and technicians who need to link older serial instruments, PLCs, or modems to modern laptops or desktops will find this adapter practical. It is not intended for users who require a male DB9 connector or a longer cable run beyond the supplied length. Buyers needing multiple simultaneous serial ports should look at a multi-port solution instead.

Check your device gender and driver needs

Verify that the serial peripheral you are connecting presents a male DB9 port, because this adapter provides a female DB9 socket. Ensure your operating system matches the supported list so the FTDI driver installs correctly. Confirm that a USB Type-A host port is available on the target computer. No external power supply is required.

Questions about this item

What kind of USB port does my computer need for this adapter?

The adapter plugs into a USB 2.0 Type-A port on your computer and provides a DB9 serial port for the connected device.

Will this adapter work with a legacy serial device that draws power from the DB9 port?

The adapter is USB-powered and uses an FTDI chipset; it does not supply power on the DB9 pins, so the serial device must be self-powered.

How can I confirm the adapter is recognised after I plug it in?

Check Device Manager on Windows or run `lsusb` on Linux; the FTDI chipset should appear as a USB serial port with a COM or ttyUSB assignment.
