How to use
Connect the USB Type-A plug to an available USB port on the computer and attach the DB-9 (female) connector to the serial device.

On supported operating systems the driver will install automatically; if necessary download drivers from the manufacturer. Monitor the adapter LEDs to confirm USB enumeration and data transmit/receive activity.
