Why choose this product

Reliable Connectivity for Essential Devices

The TRENDnet TUC-S9 USB-C to RS-232 adapter ensures your critical legacy serial devices remain functional with modern computers. Unlike basic adapters, its robust build and integrated 1.8m cable offer superior flexibility and durability for consistent connections. This adapter is engineered for straightforward integration, allowing you to connect point-of-sale systems, industrial equipment, or older printers without complex driver issues on Windows.

Ideal for Specific Setups, Not General Use

This adapter is perfect for users needing to connect specific RS-232 serial devices to a USB-C port on Windows laptops or desktops. It is not designed for connecting USB-C devices to serial ports or for use with macOS or Linux systems. For users requiring serial-to-serial connections or specific industrial protocols, alternative adapters may be necessary.

How to use

  • Connect to Laptop — Plug the USB Type C end of the TRENDnet TUC-S9 adapter into an available USB-C port on your Windows laptop or desktop computer.
  • Connect Serial Device — Connect the RS-232 (9-pin male) end of the adapter to the corresponding serial port on your legacy device, such as a POS system, modem, or printer.
  • Install Drivers (if needed) — Windows should automatically detect the adapter and install drivers. If prompted, or if the device is not recognized, download the latest drivers from the TRENDnet support website for your specific Windows version.
  • Verify Connection — Once drivers are installed and devices are connected, check your device's software or system settings to confirm the serial port is recognized and communicating correctly.
