DLP Light Commander

The DLP Light Commander is a projector with really, really fast refresh rates and precision timing.

Overview

Quick Stats
Resolution	1024x768 only
Compatible OS	32-bit Windows XP only
Static Image Frame Rate (Monochromatic)	6 Hz to 5000 Hz
Dynamic Input Frame Rate (Colour)	60 Hz
Dynamic Input Frame Rate (Monochromatic)	1440 Hz
Onboard Memory	90MB, enough for 960 bit planes
Part Number	1015647
Serial Number	2910M00395

The DLP Light Commander is a projector that allows for extremely high frame rates, precise control over exposure time, colour balance of monochromatic light, and IR light. It is extremely finicky but very powerful. It runs on 32-bit operating systems only, and has only been tested with Windows XP. There are three different modes for display: Video, where it operates as a normal colour projector at up to 60 Hz; Structured Light, where it displays a series of static, monochromatic images read from onboard memory at rates of up to 5000Hz; and Real Time Structured Light, where it displays monochromatic images from a dynamic input (such as DVI) at up to 1440 Hz. In the software, Structured Light and Real Time Structured Light are differentiated only by source - they are both found under "Structured Light".

Installation & Start up

Hardware

The DLP Light Commander comes with a power cord, a USB cable, an HDMI to DVI converter cable (the HDMI end connects to the projector itself), and a user manual.

Software Download and Installation

Go to the following link and click on support:

http://www.logicpd.com/products/development-kits/dlp-lightcommander-development-kit

You will need to sign up for an account. To register, you will need the following information:

• Part #: 1015647
• Serial #: 2910M00395

Download the control software and the software user manual, which should give you the following files respectively:

• 1017179A_DLP_LC_Control_SW_1-0-73-859.zip
• 1015703Rev2_DLP_LightCommander_SW_UM.pdf

Extract the zip file and install the software.

Turning the Projector On

1. Plug the projector into a power source, leave it turned off
2. Switch the projector to "Run" rather than "Park"
3. Plug the USB cable
4. Install the USB driver automatically (if necessary), or wait until the computer recognizes the projector
5. Start up the control software

Using the Control Software

The Different Modes

There are three different modes for display: Video, where it operates as a normal colour projector at up to 60 Hz; Structured Light, where it displays a series of static, monochromatic images read from onboard memory at rates of up to 5000Hz; and Real Time Structured Light, where it displays monochromatic images from a dynamic input (such as DVI) at up to 1440 Hz. In the software, Structured Light and Real Time Structured Light are differentiated only by source - they are both found under "Structured Light".

Important: When changing whether a project is using one of the Structured Lights or Video, you must create a new project. The software fails to compile when you change this without creating a new project.

Tips & Tricks

• If the projector is reading input from DVI and is not displaying correctly, try the following:
  1. Put the projector into "Park"
  2. Pull the HDMI end of the cable out of the projector
  3. Plug the HDMI cable back in
  4. Put the projector into "Run"

Additional Features

There are several additional features that have not been confirmed by a PSM lab member.
