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.
