Description

StarTech ICUSB232DB25 USB to Serial RS232 Adapter

Overview

The StarTech ICUSB232DB25 provides a bridge between modern USB ports and legacy serial devices, enabling you to connect RS232 peripherals like barcode scanners, industrial equipment, or older network devices to a computer lacking a native serial port. This adapter is particularly useful in environments where existing infrastructure relies on serial communication, such as manufacturing floors or older surveillance DVRs that require direct serial control or data logging. The ICUSB232DB25 model includes both DB9 and DB25 connectors, offering broad compatibility for devices using either serial interface. It supports data rates up to 230.4 Kbps, ensuring efficient communication for most serial applications.

Compatibility

This USB-to-serial adapter is compatible with Windows operating systems (XP through 11), macOS, and Linux distributions. It utilizes the Prolific PL2303GC chipset, which is widely supported across these platforms. The adapter is designed to interface with any device requiring an RS232 serial connection, including but not limited to: industrial automation controllers, point-of-sale systems, older network switches, and certain legacy security system components. The included DB9 and DB25 connectors ensure it can adapt to a wide range of serial cabling configurations.

Installation Notes

The adapter operates within a 0°C to 70°C (32°F to 158°F) temperature range, suitable for most indoor environments. Storage temperature ranges from -40°C to 85°C (-40°F to 185°F). It requires a USB 2.0 port for operation and draws minimal power, typically not requiring an external power supply. The included 3-foot cable provides moderate reach for connecting devices.
