Product information

Description

The StarTech ICUSB232INT2 Internal USB Motherboard Header to 2 Port Serial RS232 Adapter adds two RS-232 serial ports to a desktop system using an available internal USB motherboard header. Designed for installation inside the PC case, the adapter provides a tidy internal connection without external cables or adapters. It supports standard serial communication requirements and bridges modern motherboards with legacy serial peripherals.

Advantages

This internal USB-to-serial adapter supports two RS232 ports while occupying a single internal USB header, offering a compact solution for connecting legacy serial devices. It provides a 256-byte FIFO buffer and supports common baud rates up to 115.2 Kbit/s. The product is certified (WHQL, CE, FCC) and includes StarTech.com technical support and a two-year warranty, ensuring compatibility and reliable operation in supported environments.

Suitable for

  • Connecting serial peripherals such as modems, industrial controllers or POS devices to a desktop PC
  • Systems where an internal, clutter-free serial connection is preferred over external cables
  • Upgrading modern motherboards that lack built-in RS232 ports

How to use

Install the adapter inside the PC case by connecting its IDC connector to an available internal USB motherboard header. Secure the adapter and route the serial ports to the desired external access point or bracket as required by your chassis.
