Software/Firmware Upgrade Process

How to Download Firmware

Hardware required

1. Standard USB Download cable (P/N 50.73213.501)

2. Personal computer or laptop computer

Software required

1. DDP2000 Composer lite

2. New version FW

DDP2000 Composer lite install procedure

Installation Location

The default installation directory is:

C:\Program Files\DLP Composer Lite

If you want to install to a different directory (perhaps alongside a prior release of DLP

Composer™ Lite), click the "Browse" button on the "Select Features" page..

USB Support - Installation (All Platforms)

This release includes support for a USB communications interface to DDP2000-based

projectors. The setup program includes the files needed to install USB support (for

Win98/WinMe/Win2K/WinXP only -- Win95 and WinNT are not supported).

After DLP Composer™ Lite is installed, to install the USB support, choose the "Install

DDP2000 USB Driver" icon under "DLP Composer™ Lite" in your Start menu.

USB Support - Win98/WinMe Only

Installation on Windows 98 or Windows Me may prompt "Please insert the disk labeled 'DLP

Composer Installation Directory', and then click OK". This message may be safely ignored

by clicking the OK button.

Another prompt will then appear: "The file 'windrvr6.sys' on DLP Composer Installation

Directory cannot be found". Again, click OK and the installation proceeds without further

problems.

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.
