1 Port FTDI USB to Serial RS232 Adapter Cable with Optical Isolation

StarTech ID: ICUSB2321FIS

The ICUSB2321FIS 1-Port FTDI USB to Serial RS232 Adapter Cable with Optical Isolation converts an
available USB 1.1 or 2.0 port into an RS232 DB9 port that can be used to connect, monitor and control your
serial devices.

The USB to serial adapter features integrated optical isolation circuits and surge protection to protect your
critical, sensitive control equipment against electrical damage, making it a viable solution for costly industrial
serial devices.

The versatile FTDI chipset also supports COM retention, additional customization/features, and compatibility not
offered by most other solutions. Broad operating system compatibility including Windows®, Windows CE, Mac
OS and Linux, makes this product easy to integrate into mixed environments.

Backed by a StarTech.com 2-year warranty and free lifetime technical support.
