Description

StarTech ICUSB2322F Dual-Port USB to Serial RS232 Adapter

Overview

The StarTech ICUSB2322F provides a reliable bridge between modern USB-equipped systems and legacy serial RS232 devices. This adapter is critical for integrating industrial equipment, point-of-sale systems, or older surveillance hardware that relies on serial communication. Its integrated 2500Vrms optical isolation protects connected equipment and the host system from damaging voltage spikes and ground loop interference, making it suitable for electrically noisy environments or when connecting to equipment with uncertain grounding.

Compatibility

This adapter is powered by the FTDI FT2232D chipset, ensuring broad compatibility with most serial communication applications and operating systems. It supports data rates up to 921.6 Kbps, accommodating a wide range of serial devices. The adapter is designed for use with systems requiring RS232 communication, such as industrial controllers, scientific instruments, and older network devices. It presents two standard DB-9 male serial ports, each capable of independent configuration for data bits, parity, and stop bits.

Installation Notes

The ICUSB2322F is USB-powered, eliminating the need for an external power adapter and simplifying deployment. The integrated cable is 6.6 ft (2 m) long, providing ample reach for most workstation setups. Operating temperature range is 0°C to 55°C (32°F to 131°F), with storage temperatures from -20°C to 85°C (-4°F to 185°F). It requires a free USB 2.0 port on the host system.
