Overview

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 re-assigned 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.

The StarTech.com Advantage

  • The FTDI chipset is highly customizable and compatible, making it the ideal solution for any setup
  • Portable USB-Powered design requires no bulky power adapter or outlet
  • Simple installation and operation with COM port retention provides robust serial connectivity for legacy devices

(5 stars) Com Port Retention makes life easier

We have several of these deployed and the Com Port Retention makes life easier for our clients - and we've never had a failure. So we are quite happy with this product.

(5 stars) Worked Flawlessly

By:
I was unable to upgrade firmware and/or control my iOptron mount with the KeySpan Tripp-Lite USB to Serial cable. It was suggested by iOptron that I get the FIDI cable instead. A member of our Astronomy club recommended Startech.....and the rest is history. I would not hesitate using this company for additional needs.
