USB Support - Using a projector for the first time
After installation is complete, and you plug a DDP2000-based projector into USB for the first
time, Windows will run the "New Hardware Wizard". When the wizard prompts to find the
necessary drivers, accept the recommended choice (let the system find the driver for you)
and click "Next" to complete the installation.
Note: The Windows 98/Me "New Hardware Wizard" may not automatically find the
driver. You should use the "Advanced" option, and enter the directory where the DLP
Composer™ Lite Tool Suite was installed (normally "C:\Program Files\DLP Composer
Lite"). The wizard will find the file "DDP2000.inf" and complete the installation.
USB Support - Choosing the USB interface
To select the USB communications interface, choose "Preferences" from the "Edit" menu,
click the "Communications" page and choose "USB (DDP2000 Only)". You can now use
DLP Composer™ Lite to communicate with a DDP2000-based projector via USB using the
Flash Loader tool.
