Description
This item is brand-new, factory sealed.
Add RS-232 serial communication support to USB-C laptops or desktops using this 6.6ft (2m) USB-C to DB9 null modem serial adapter cable.
Serial Port Expansion
The adapter adds an RS-232 DB9 female connector through a USB Type-C port. The cable improves reach to serial equipment and supports cleaner routing behind desks, workstations, kiosks, or service benches. Secure it with pre-installed removable DB9 screws or install the included DB9 nuts 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.
