USB-C to DB9 serial adapter

The Tripp Lite U209-005-C connects a 9-pin RS-232 peripheral to a USB-C port on a computer, laptop, tablet or smartphone. It supports data transfer speeds up to 230 Kbps without requiring an external power source. The five-foot cable uses 28 AWG data lines and 24 AWG power lines under a PVC jacket.

Check host port and OS support

Your host device must provide a USB-C port that operates in USB 2.0 mode or higher. Windows, Mac, Linux and Android devices with USB Host Mode (OTG) are supported. Verify that your serial peripheral uses a standard DB9 male connector and RS-232 signalling before ordering.

For legacy serial gear on modern ports

This adapter suits engineers, technicians and hobbyists who need to link modems, industrial equipment or older scientific instruments to current USB-C hosts. It is not for buyers who require a USB-A connection, parallel-port support or data rates beyond 230 Kbps.

Questions about this item

Does the Tripp Lite U209-005-C cable include any driver CD or software, or is it ready to use immediately?

The cable is a USB 2.0 device that works with Windows, Mac and Linux computers as well as Android devices supporting USB Host Mode without requiring an external power source; any necessary drivers are typically supplied by the operating system or available from the chipset vendor.

Should I choose a different length or chipset version of the U209-005-C for my application?

This model is a fixed five-foot cable using a USB 2.0 USB-C to RS-232 interface; no alternative lengths or chipset variants are offered under this part number.

What does the 230 Kbps rating mean when I connect a legacy serial device to a modern USB-C laptop?
