Product Information

Full details

The StarTech.com ICUSB232INT1 is designed for users needing to connect legacy RS232 serial peripherals to modern desktop systems that lack native serial ports but have an available internal USB motherboard header. Its key benefit is providing a clean, internal solution that bridges this compatibility gap cost-effectively. A potential caveat is that it requires an internal USB header, making it unsuitable for systems without one. This adapter offers a single RS232 port, features a FTDI chipset for reliable performance, and includes necessary mounting brackets for easy integration.
