Connecting a laptop computer requires a VGA cable and, if needed,
an audio cable and a network cable (with wireless networking no
network cable is needed). An audio cable would be
used if you desire to employee the wall speakers for sound coming from the computer. For this demonstration, a laptop
computer was obtained from the LLRC. If you are using your own laptop or one obtained from
WSU's Instructional Support Services, the
connections may be found in different locations and may look different than those illustrated below. It
is important to be familiar with the computer before you begin to connect it to the Dukane system.
The first thing to note is that the LLRC laptops are all using
wireless networking (actually we do have one Compaq laptop (light grey)
without wireless - it requires connecting a network cable).
The wireless laptops do not require a network cable however they do
require that you authenticate your wireless connection if you wish to
use the Internet. To authenticate wait until the laptop has
started up and loaded the default desktop (it will do this
automatically). At this point you must double-click the "Wireless
connection" icon on the desktop and enter your networkID and
password (again, you only need to do this if you wish to use the
Internet). The wireless software will authenticate you and load
your network connection. If the authentication
fails, click on cancel and restart the process by
double-clicking the "Wireless connection" icon again.
Once you are authenticated you can open and use your Internet browser.
The picture below illustrates the proper connection of the VGA cable to the video port found on the back of the computer.
The computer is now ready to be
connected to the Dukane system.
The computer inputs are located directly below the control panel, and consist of Ethernet, Computer Video,
and Computer Audio. The Network cable should be connected to the Ethernet
port (unless you are using a wireless connection), and the VGA cable should
be connected to the Computer Video port.
The audio cable plugs into the port labeled "Computer
Audio" on the Dukane system and into the headphone jack on your
laptop (on your laptop this port is often labeled with a headphone
icon or a port colored green).
The following picture illustrates the computer properly
connected to the Dukane system.
Once everything is connected, you are ready to turn on the computer and the Dukane system. For the
computer video to display correctly, it is important that the Dukane
system be turned on first. To turn on the Dukane system press the POWER
button (you should see a blue light appear in the projector as it
comes on). To view the computer
material, you then need to press FUNC, followed by B on
Dukane system. Once the Dukane is on then start up your laptop
computer. If your laptop is already running when you connect the
video cable to the Dukane system you may need to follow the
instructions below in order to see the image on the Dukane
projector. If you seem unable to get the image to display on the
Dukane Projector then shut down all equipment and follow the
instruction noted above.
IF NO IMAGE SHOWS UP ON THE DUKANE SYSTEM PROJECTOR:
An important feature to remember is that you can toggle between three
video output settings on your laptop. The first displays an
image only on your laptop LCD screen, the second displays an image
only on the Dukane projector, and the third displays identical images
simultaneously on both the Dukane projector and the laptop
LCD. To reset video output on your laptop find and hold the fn key
(usually found
between the ctrl and alt keys), then press the LCD/CRT key
(this is often the F8 key) then release both
keys. Please remember that it will take the laptop a moment to
reset the video so be patient.
If you are projecting DVD's with your laptop, it is recommended that you toggle
the image onto the Dukane projector only.
