StarTech ICUSB232SM3 USB to Serial DB9 Adapter
Overview
The StarTech ICUSB232SM3 provides a bridge between modern USB-equipped systems and legacy serial devices. This 3-foot cable adapter is essential for integrating older industrial equipment, scientific instruments, or point-of-sale terminals that rely on RS232 communication into a USB-only environment. It leverages the Prolific PL2303GC chipset for reliable data transfer, ensuring your serial peripherals remain functional without requiring complex driver installations on most operating systems.
Compatibility
This adapter is designed to interface with any standard DB9 serial port. It supports USB 1.1 and USB 2.0 host controllers, making it compatible with a wide range of PCs and laptops. The adapter is recognized by Windows operating systems (XP and later) and macOS, providing broad compatibility for diverse IT infrastructures. It's suitable for connecting devices such as serial printers, barcode scanners, network switches, and modems that utilize RS232 signaling.
Installation Notes
Operating within a 0°C to 60°C (32°F to 140°F) temperature range, this adapter is suitable for most standard office and light industrial environments. The adapter itself draws minimal power via USB and does not require an external power supply. Its compact dimensions (36.0 in length, 1.4 in width, 0.6 in height) allow for easy placement behind workstations or within tight equipment racks.
