1 Port FTDI USB to Serial RS232 Adapter Cable with COM Retention
StarTech ID: ICUSB2321F
The ICUSB2321F 1-Port USB to Serial RS232 Adapter Cable with FTDI chipset and COM Retention converts
an available USB 1.1 or 2.0 port into an RS232 serial DB9 port to connect, monitor and control your serial
devices.
This compact adapter features COM retention, allowing the same COM port value to automatically be reassigned to the port if the cable is disconnected and re-connected to the host computer, or if the system is
rebooted. The ICUSB2321F uses the FTDI chipset which supports additional customization, advanced features,
and compatibility not necessarily offered by other solutions.
Compatibility with a broad list of Operating Systems 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.
