Product information

Description

The StarTech.com ICUSB2321X is a professional-grade USB to serial adapter cable that converts a USB 2.0 port into a single RS232 DB-9 serial port. The compact cable design with a USB-A connector and a DB-9 male connector enables connection of legacy or industrial serial devices to modern computers. The adapter supports COM port retention so assigned COM port values are preserved and automatically re-assigned when the adapter is disconnected and reconnected to the host system.

Advantages

This USB to Serial Adapter Cable provides a durable single-cable solution for technicians and administrators requiring mobile serial connectivity. It offers plug-and-play installation with USB-powered operation, eliminating the need for an external power supply. The adapter is compatible with a wide range of operating systems and preserves serial settings via COM retention, reducing setup time when reconnecting devices. The product is backed by a 2-year warranty and free lifetime technical support from StarTech.com.

Suitable for

  • Connecting RS232 devices such as serial modems and barcode scanners to modern PCs
  • Field technicians and administrators who need portable serial connectivity
  • Industrial or legacy equipment integration where USB ports are available

How to use

Connect the USB-A end of the ICUSB2321X to an available USB 2.0 port on the host computer and attach the DB-9 connector to the serial device. Install any required drivers if prompted by the operating system; many systems support plug-and-play operation. Verify the assigned COM port in the host system’s device manager or serial settings and configure your serial application to use that COM port. When disconnected and later reconnected, the adapter will attempt to retain and restore the previously assigned COM port value.

Usage recommendations

Use standard shielded cabling for serial connections and avoid running the cable near high-power or noisy electrical equipment. For critical or industrial deployments, confirm driver compatibility with your operating system and test the COM retention behavior in your specific environment before permanent installation.
