Axagon ADS-1PSN cavo adattatore USB-A 2.0 - seriale RS-232 DB9-M Prolific 1,5 m

The AXAGON ADS-1PSN active USB converter expands a computer with a standard RS-232 serial port using an original Prolific PL2303GT chip. The adapter has a fixed 1.5 m USB-A cable with gold-plated connectors and a durable, double-shielded body suitable for desktop and laptop use as well as industrial environments. It supports plug-and-play operation and powers from the USB bus, allowing connection of barcode readers, receipt printers, scanners, microcontroller programmers, CNC machines, modems and other RS-232 devices.

Advantages

Built with an original Prolific chipset and gold-plated contacts for reliable signal transmission and long life. The adapter’s rugged housing, double shielding and 1.5 m fixed cable provide stable operation in both consumer and industrial settings. Bus-powered design removes the need for an external power supply and wide OS support ensures compatibility with Windows, macOS, Linux and many Android versions.

How to use

Connect the fixed USB-A cable to a free USB port on your computer. Plug the device requiring an RS-232 interface into the DB9 male connector on the adapter. The adapter is bus-powered and does not require an external power supply. Install or let the operating system automatically install the appropriate driver if prompted, then select the assigned COM port in your application or device configuration and adjust baud rate and serial parameters as needed.

Recommendations

Use the AXAGON ADS-1PSN to connect legacy RS-232 equipment—such as barcode scanners, cash register printers, CNC controllers and modems—to modern computers. For stable communication, ensure correct COM port and serial settings (baud rate, parity, data bits and flow control) match the connected device.
