Issue: Can’t connect to subwoofer.
Solution:
• Make sure subwoofer is on.
• Make sure USB cable is connected to both computer and subwoofer.
• Try plugging the USB cable into a different USB port on your computer.
• You may need to re-install the USB Virtual COM port driver. Re-insert the Velodyne Digital Drive PLUS Windows Setup Program CD into
your computer. You can cancel out of the install at the language selection prompt.
Issue: Windows still asks for USB drivers after running the program disc.
Solution:
On your program CD is an archive file named “FTDI USB Driver XXXXXX”. The file XXXXXX is a numeric date. Copy this executable
file to your computer and extract the files. Direct the Windows hardware wizard to this extracted folder.
Issue: You hear an audible hum while your laptop is connected to the subwoofer through the USB port.
Solution:
The hum is caused by the laptop power supply. The power supply doesn’t have a ground loop isolator, which means you can get cross-
talk noise/hum when any USB device, including the Digital Drive PLUS subwoofer, is connected to the power supply. To eliminate the hum:
• (Recommended) Disconnect the power supply and run the laptop on battery power when using the Windows Setup Program; or
• Plug the laptop into a 3-prong to 2-prong adapter and then into the power outlet.
