Axagon ADS-1PQN USB-A 2.0 - serial RS-232 DB9-M FTDI adapter cable 1.5m - Adapter - Digital/Daten serial cable Black USB Type-A

The AXAGON ADS-1PQN is an active USB-A 2.0 to RS-232 serial adapter with a permanently attached 1.5 m cable and integrated DB9 male connector. It uses the original FTDI FT232RL chip and a TI serial line driver to provide wide compatibility and stable data transfer for connecting computers to RS-232 devices. The adapter is bus-powered via USB and features gold-plated connectors, double shielding and a durable housing suitable for both office and industrial environments.

Advantages

The adapter provides high compatibility thanks to the original FTDI chip and supports Plug and Play installation on Windows, macOS, Linux and many Android versions. Gold-plated contacts reduce oxidation and improve reliability while double shielding and a robust body increase resistance to interference and mechanical stress. A fixed 1.5 m USB-A cable simplifies connection to desktop PCs and laptops without needing an additional cable.

Suitable for

• Connecting barcode readers and receipt printers
• Configuring or upgrading set-top boxes and security devices
• Interfacing CNC machines, modems and industrial controllers
• Connecting scanners, microcontroller programmers and transmitters
• Use in desktop and laptop environments where an RS-232 DB9 port is required

How to use

Connect the fixed USB-A plug to a computer USB port and attach the integrated DB9 male connector to the RS-232 device. The adapter is bus-powered and does not require an external power supply. On supported operating systems drivers are installed automatically; if necessary, install drivers provided by the OS or from the FTDI vendor. Configure COM port settings (baud rate, parity, flow control, stop bits) in your terminal software or device configuration tool to match the connected device.

Recommendations

For reliable operation, use a direct USB port on the computer rather than an unpowered USB hub. Match serial settings exactly to the connected device and keep the cable away from strong electromagnetic sources to reduce interference. If automatic driver installation fails, download the FTDI drivers from the official FTDI website or use the OS-supplied driver.
