How to use

Connect the USB Type-A plug to an available USB port on your laptop or desktop. Attach the DB9 connector to the serial device; if the device uses a DB25 port, attach the supplied DB9-to-DB25 adapter before connecting. The adapter supports plug-and-play operation on most systems; if drivers are required, install the appropriate StarTech.com driver for your operating system. Position the integrated cable so it does not strain the device or the USB port.

Usage recommendations

For reliable communication, use the adapter at short cable runs and avoid sharp bends in the integrated cable. Verify device settings (baud rate, parity, stop bits) match on both the computer and the serial peripheral. If intermittent connectivity occurs, confirm correct driver installation and try a different USB port or a powered USB hub.
