The LCD Video projector is set up to project from the following sources: the local computer, DVD/VHS VCR, a document camera, and from the auxiliary jacks on the tie plate located on the left side of the instructor's station. The Dell 755 Intel Core 2 Duo 2.66GHz computer is equipped with an 80GB SATA 10000rpm hard drive, 4GB RAM, a CD-RW/DVD+/-RW, and a graphics card. These devices, as well as the auxiliary audio ports located on the tie plate are connected to an amplifier and speakers. Devices are selected and controlled from the LCD AMX touch panel, located at the top of the instructor’s station. The local computer is connected to the backbone network. A wireless mouse is available (contact the Media Center 83059 for information).

The auxiliary jacks on the tie plate include a 15-pin male VGA connector with associated network jack and stereo ¼" mini jack (for portable computers) and auxiliary RCA video connector with associated RCA audio jacks. AC power is also available. These auxiliary jacks are provided for clients who wish to use their own equipment and associated cables. Connection of Macintosh or PC laptops to this auxiliary input requires an interface cable, provided at the instructor’s station.

• Clients must know how to feed VGA signal out of their laptops.
• Note that the projector does not turn on instantly. It can take as long as 30 seconds for a picture to become visible. Please be patient when selecting inputs.
• If there is no sound, check the audio mute button and the volume up arrow on the AMX touch-pad.
• If there is no picture be sure the correct input is selected and that "picture off" has not been selected.

Wolf Vision Digital Document Camera Instructions

The instructor’s station in this room has been equipped with a digital document camera.  This high quality instrument will enable you to project material from paper, transparencies or even three-dimensional objects to the projector.  To operate this camera:

1. Turn on the projection system using the touch-screen control.  Select the document camera from the source menu at the top of the screen.
2. Raise the camera arm by pulling up on the small blue lined ring.
3. Turn the camera head so the lens points down.  Focus and Zoom buttons should be facing you.
4. Press the power button on the rear left of the base (a green light indicates on).  The light should come on.  If it does not, press the light button as needed.  Note, this camera does not have a bottom light for overheads.  The base surface is sufficiently reflective to allow use of overheads with the top light.  Do not write on the base.
5. Place your work on the base.  You should see it displayed on the touch-screen preview monitor and on the projector screen.
6. Camera controls are located along the top of the camera head:

• Focus defaults to automatic (green light on).  The picture should self-focus and remain in focus as you operate the zoom.  There may be a slight delay.  The automatic focus can be switched off (useful if you are writing on paper)
• Zoom in with the button marked with a single figure and a + sign.  Note that there is a digital zoom feature that doubles the range of the mechanical zoom.  The camera can resolve an object of about one inch square.
• Zoom out with the button marked with three figures and a – sign.

7. The camera head can be rotated to shoot outside of the working surface.  Turn the light out of the way, pull the close up lens out from the front of the camera (it will not fall out), and rotate the camera head.
8. When you are done with the camera please

• Turn off the power
• Lower the camera by rotating the camera head down and then pulling the blue lined ring towards you.
