Instruction Manual

Introduction

The ICUSB2322F/ICUSB2321F 2-Port USB to Serial RS232 Adapter Cable with FTDI

chipset and COM Retention converts an available USB 1.1 or 2.0 port into 2 RS232 serial

DB9 ports to connect, monitor and control your serial devices.

This compact adapter features COM retention, allowing the same COM port values 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. Unlike most USB-serial adapters,

this one uses the FTDI chipset, which supports additional customization, advanced

features, and compatibility not necessarily oered by other solutions.

This USB-serial adapter is compatible with a broad list of Operating Systems, including

Windows®, Windows CE, Mac OS and Linux, making this product the perfect solution

for integrating into mixed environments.

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