FAQ

The StarTech.com ICUSB2321X is a professional-grade USB to Serial adapter that converts a USB 2.0 port into an RS232 serial port. It allows users to connect, monitor, and control legacy or industrial RS232 serial devices (such as barcode scanners, serial modems) to modern computers through USB, eliminating the need for expensive peripheral upgrades.
