Product information

Description

The StarTech.com 3ft USB to Serial Cable (1P3FP-USB-SERIAL) provides a single RS-232 DB9 male COM port via a USB Type-A connection. With a 0.91 m (3 ft) cable, Prolific chipset compatibility and a maximum data rate of 921.6 Kbps, the adapter connects modern computers to legacy serial devices such as PLCs, printers, barcode scanners and AV equipment. It supports Windows, macOS and Linux and is backed by a 3-year StarTech.com warranty with multilingual technical support.

Advantages

This USB to RS232 adapter offers simple plug-and-play connectivity for host devices with USB Type-A ports, while maintaining compatibility with USB 2.0 and other USB revisions. Its compact form factor and reliable data transfer at up to 921.6 Kbps make it suitable for point-of-sale systems, industrial control and office peripherals. The integrated Prolific chipset ensures broad operating system support and stable serial communication.

How to use

Plug the USB Type-A connector into an available USB port on your computer and connect the DB9 male connector to the serial device. Install drivers if required by your operating system; many modern OS versions auto-detect the adapter and install the appropriate Prolific driver. After connection and driver installation, the adapter appears as a COM port in your device manager or serial terminal software, allowing standard serial communication at the supported baud rate.

Usage recommendations

For stable operation, use drivers provided by StarTech.com or the Prolific vendor that match your OS version. Keep cable runs within the 0.91 m length to avoid signal degradation and verify COM port settings (baud rate, parity, data bits, stop bits) in your terminal or application to match the connected serial device.
