How do I use the classroom projection systems?

Pratt Classroom Projection Systems

Numerous classrooms at the Pratt School of Engineering have projection systems in them allowing for the use of multimedia materials during classes and presentations.

We currently have two different classroom configurations: Stand-Alone Projectors and Complete A/V Systems

Complete A/V Systems

Rooms: Hudson 125, Teer 203

These classrooms have podium mounted computer systems and complete audio-visual systems. Audio, video, computer, projection screen, and lighting are controlled via a Crestron touch-screen. The projector & audio system can be switched between the podium computer, an attached laptop, TV Tuner, and VCR.

Below are instructions for common operations in the Complete A/V System rooms:

Raise/Lower Projection Screen: The screen is controlled via the touch screen. Select 'Room Controls' and then 'Screen' Use the up and down arrows to raise/lower the screen.

Stand-Alone Projectors

Rooms: Hudson 115a, 201, 207, 208, 212, 216, 218, 222

These classrooms have ceiling mounted projectors in them which you can connect to directly via wall mounted connectors. However, you can also connect to the projectors over Duke's Wireless Network allowing you to simply open your laptop, start a simple client, and send your computers desktop to the projector over Duke's network.

NOTE The wireless connection method can be used for most presentations. However, if your materials include any kind of animation, movie, etc., you should connect directly to the projector using cables as the network client can only send a few images per second to the projector.

Our projectors have a resolution of 1024x768. Make sure you set your laptop to this resolution or the projected image will not look very good.

Connecting via Wireless Network

1. Your computer must have a wireless card installed and it must be registered. If you have not registered your wireless card, open up a web browser and go to any website. You will be redirected to a registration page to register your wireless card. If you are not affiliated with Duke, contact Pratt Technology Services (660-5400) to obtain a loaner wireless card for your system.

2. Download and install the Epson Projector Control Client (won't work for 115a, 218, 222). You only need to do this once.

3. Turn on the projector using the small remote attached to the front wall or podium.

4. Once the projector lamp warms up, you will see a welcome screen which includes the projector's IP address. NOTE The IP addresses may change - do not assume the IP will be the same in a room for the entire semester. Look!

5. Start the Epson Projector Client and enter the projector IP when prompted

6. Enter the random Projector Keyword displayed on the screen - this ensures someone cannot control the projector remotely

7. Your PC's desktop should now appear on the screen. Start whatever software you need for your class/presentation.

Direct Connection

1. Locate the projector ports. They should be on the front wall next to the chalkboards.

2. You must bring a standard Male to Male VGA cable to connect your laptop to the projector port. If you need audio, you will also need a Male to Male 1/8" audio cable. You can borrow the necessary cables from Pratt Technology Services. Call 660-5400.

3. Put your laptop into external video mode PCs: Most laptops can operate in three modes: LCD Display Only, External VGA Port Only, and dual display. The latter mode will mirror the laptop's LCD display on the projector. Most people choose this third mode. Most laptops use a function key to toggle between video modes. Powerbooks: Apple PowerBooks allow the external video port to display differnet windows than the built in LCD display. This can be handy if your presentation software has a control panel and presentation panel. However, most people will want to use 'Mirror' mode so it acts like the PCs above. Start 'System Preferences', select 1024x768 resolution, and select 'Mirror Displays'

4. Your desktop should now appear on the projection screen. Below are instructions for common operations in the Stand-Alone Projector rooms:

The screens are manual pull-down screens with controlled return. This means to raise the screen you simply give the screen a gentle tug and let go. The screen will slowly wind itself up.
