StarTech 1ft (30cm) USB-C to Serial Adapter Cable, COM Retention, FTDI Chipset, Type-C to DB9 RS232, Status LEDs, DB9 Nuts and Screws

Add RS-232 serial communication support to USB-C laptops or desktops using this 1ft (30cm) USB-C to DB9 serial adapter cable.

Serial Port Expansion

The adapter adds an RS-232 DB9 male connector through a USB Type-C port. The cable enables close-range serial connections, reducing excess slack to keep desks, workstations, kiosks, or service benches clean and organized. Secure it with pre-installed removable DB9 nuts or install the included DB9 screws for expanded compatibility with serial peripherals.

LED Indicators

Transmit, Receive, and USB LEDs show activity and host recognition for faster setup and at-a-glance troubleshooting.

Seamless Connectivity

The FTDI-based adapter supports Windows, macOS, ChromeOS, and Linux. Driver auto-install and COM retention help maintain serial access after reboots or reconnects.

Built To Last

Molded TPE housing adds rugged protection against flexing and wear, while the Level-4 ESD (15kV air/8kV contact) protection helps protect connected devices from static discharge. Copper shielding helps minimize interference for cleaner signal transmission, and gold-plated connectors resist corrosion for long-term connection reliability. Rated for -40°C to 80°C operation, the cable is built for dependable performance in demanding industrial and commercial environments.
