Product information

Description

The StarTech.com ICUSB2321F is a 1-port USB to Serial RS232 adapter cable that uses an FTDI chipset and provides COM port retention. It converts a USB 1.1 or 2.0 Type-A port into a DB-9 RS232 serial port, offering a compact, portable solution for connecting, monitoring and controlling legacy serial equipment. The cable is 0.2 m long, comes in black, and is USB-powered so no external power adapter is required.

Advantages

The FTDI chipset delivers broad compatibility and supports additional customization and advanced serial features. COM retention ensures the adapter retains the same COM port assignment after disconnection, reconnection or system reboot, simplifying device management. The USB-powered, compact design enables easy transport and use without a bulky power supply, and the adapter supports multiple operating systems including Windows, Windows CE, macOS and Linux.

Suitable for

Connecting industrial or laboratory equipment with RS232 DB-9 interfaces
Point-of-sale systems, barcode scanners and receipt printers that require serial communication
Legacy serial devices in mixed OS environments (Windows, macOS, Linux)
Field service and mobile setups where a portable USB-powered serial connection is needed

How to use

Install the appropriate driver for your operating system if required (FTDI drivers are commonly available for Windows, macOS and Linux). Connect the USB Type-A plug to an available USB 1.1 or 2.0 port on the host computer and attach the DB-9 connector to the serial device. Configure the COM port settings (baud rate, parity, data bits, stop bits, flow control) in your serial communication software or device manager. If the cable is disconnected and reconnected, the adapter will attempt to retain the same COM port assignment.

Usage recommendations

For reliable operation, use a direct connection to the host USB port rather than a hub when possible, and ensure you install the correct FTDI driver version for your operating system. Verify serial settings on both ends before initiating communication and keep the cable length short to minimize signal degradation.
