## Long description

The StarTech 1P3FP-USB-SERIAL is a 0.91 m USB-to-serial adapter cable that converts a USB Type-A port into a DB9 male RS-232 COM port using a Prolific chipset. Designed for connecting legacy and industrial serial devices to modern hosts, this cable supports data rates up to 921.6 kbps and is compatible with Windows, macOS and Linux systems. With a compact form factor and a common USB Type-A connector, it provides a straightforward solution for adding a single serial port to laptops, desktops and service equipment.
Advantages
The adapter uses a Prolific IC to deliver reliable USB-to-serial communication and supports high-speed serial transfer up to 921.6 kbps. Its 0.91 m (3 ft) cable length balances reach and convenience for rack, bench and desktop setups. Cross-platform driver support for Windows, macOS and Linux ensures broad compatibility with host systems. The DB9 male RS-232 connector adheres to standard serial pinouts for straightforward connection to printers, barcode scanners, PLCs, switches and AV equipment.

Key specifications

Cable length: 0.91 m (3 ft)
Chipset: Prolific IC
Maximum data rate: up to 921.6 kbps

How to use
Plug the USB Type-A end into an available USB port on your computer and connect the DB9 male connector to the serial device. If required, install the appropriate driver for your operating system — the cable supports native drivers on many platforms or downloadable drivers where needed. Once the driver is installed, assign the correct COM port in your terminal, configuration software or device manager and configure baud rate and serial parameters to match the connected device. For secure mounting in racks or enclosures, route the cable to avoid strain on connectors.
Usage recommendations
For stable communication, match the serial settings (baud rate, parity, data bits, stop bits, flow control) on both host and peripheral. Use shielded routing where possible in electrically noisy environments and avoid sharp cable bends to preserve connector integrity. Check for the latest Prolific drivers for full compatibility with recent OS updates.
