PART ONE -Windows Interface for Optimization(Recommended Interface)In order to use the Windows interface to perform any setup or optimization of your Digital DrivePLUS subwoofer, the following two programsneed to be installed on your computer:• USB Virtual COM Port Driver• Velodyne’s Digital DrivePLUS Windows Setup ProgramBoth pieces of software can be fully uninstalled using normal Windows procedures as described later in this document, leaving yourcomputer in its former state.This part of this document covers:• The purpose of the driver and program.• The computer requirements for installing this driver and program.• How to install and uninstall this driver and program.• How to connect your subwoofer and the Windows Setup Program so that they communicate and share data.• How to troubleshoot connection issues between your subwoofer and the Windows Setup Program.• How to use the Windows Setup Program controls to modify and save subwoofer parameters.• How to run Self-EQ and Auto-EQPLUS optimization using the Windows Setup Program.• How to use the Windows Setup Program to perform Manual-EQ optimization.• How to update the USB Virtual COM Port driver, the Velodyne Digital DrivePLUS Windows Setup Program, the VelodyneDigital DrivePLUS subwoofer bootcode and the Velodyne Digital DrivePLUS subwoofer firmware.CAUTION: Since the DD+ subwoofer is a USB device, there is more to connecting the subwoofer to your PC than simply installing the USBcable. You should always connect the subwoofer to the PC right after running the Velodyne Digital DrivePLUS Windows Setup Program CDto allow Windows to recognize the subwoofer and complete driver configuration and installation.Virtual COM Port DriverThe USB Virtual COM Port driver allows the Digital DrivePLUS subwoofer to appear as though it was connected through a COM port eventhough it connects with a USB port. The Digital DrivePLUS subwoofer communicates usually through a COM port, such as the two RS-232connectors on the back of your subwoofer. Because most modern computers have USB ports instead of COM ports, you need to convertone of your computer’s USB ports to a COM port. Instead of having to physically perform this conversion with hardware, you can use theUSB Virtual COM Port driver to virtually perform the conversion.Velodyne’s Digital DrivePLUS Windows Setup SoftwareVelodyne’s Digital DrivePLUS Windows Setup Software is the Windows computer interface for adjusting your subwoofer’s parameters.This interface displays the same information and allows for the same parameter adjustments as the TV screen interface. However,with this interface you don’t need to access the video input connections to your TV that are often hard to reach in an already installedhome theater system.[ 2 ]Digital DrivePLUS User Interface ManualPART ONE — WINDOWS INTERFACE FOR OPTIMIZATION
