Equipment Description and Capabilities - Seating = 129, fixed chairs

The LCD projector is set up to project from the following sources: the local computer, VHS VCR, and from the auxiliary jacks on the tie plate. 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 rack are connected to the amplifier and speakers. Devices are selected and controlled from the LCD AMX touch panel, located at the top left side of the instructor’s station. The local computer is connected to the backbone network.

The auxiliary jacks provided include: 15 pin male VGA connector with associated network jack and stereo ¼” mini jack (for portable computers) and BNC video connector with associated RCA audio jack (for cameras, VCRs, document presenters, etc.) The auxiliary jacks are provided for client's who wish to use their own special equipment and associated cables.

Assistance

Instructional Technology Support Services (ITSS) may be contacted at x83059 if you wish to arrange for training on this room's features prior to using the room.  Trouble reports may be reported to the Help Desk at x8HELP (84357).

Usage of the Devices

1. Power up the equipment rack and projector by touching the AMX touch-screen located on the top of the instructor station (two or three touches may be required, one if the screen is black, one if there is a room page, and one if the text says "Touch to activate system"). Please note that the projector turns on gradually and you may not see an image for 30 seconds. A message will display as the system turns on. Please be patient.
2. Power up the computer CPU and monitor if being used (buttons on monitor and computer).  You must complete a LAN login to use a public computer by typing your user name and password in the appropriate fields in the opening dialog box.  Remember to log out when you are done.  See the "Guide to LTS Public Computing Sites and Classrooms" document for additional information on use of public sites.
3. Power up the VCR (located in the instructor station) and load tape if needed
4. Touch the button on the AMX touch-pad that corresponds to the device to be
   projected.

   “VCR” activates VHS VCR and displays the play, pause and other controls

   “Aux. Vid." input activates the Auxiliary video jack (BNC connector) and associated RCA audio jacks for client-supplied video device.

   “Computer” or "PC" activates local computer.

   “Laptop” activates the auxiliary computer jack (15pin male VGA and stereo mini audio jack) for client supplied laptop.

   “Picture Off” blanks the projector image, "Picture On" reactivates the picture

   “AUX Video” activates projector 2, auxiliary video jack (BNC connector) and associated RCA audio jacks for user-supplied video device.

Power Down the Equipment

1. Before leaving the room you MUST logout of the system. Double click the bright yellow exclamation point icon on the Windows Desktop. You may then select "Shutdown" or "Logout": one button clears the system and leaves the computer ready for the next user; the other turns off the computer. If you make no selection your account will be logged out and the system will return to the login screen. If you fail to logout, the next user of the system will have access to your account and files.
2. Remove your tape and power off the VCR, if used.
3. Press "System Power Off" button to turn off the projectors and related equipment.

Potential Problem Areas

• You must login to every public site computer. If you find a computer that is not displaying the login screen, the previous user failed to logout. Double click the bright yellow exclamation point icon on the Windows Desktop, select "Logout", and wait for the login screen.
• There is only one visible power switch for the audio system on the bottom right of the console. This switch has been covered.
• Please note that the projector turns on gradually. You may not see an image for 30 seconds. Please be patient when selecting inputs.
• The system is currently set to turn off automatically at 12 PM EST if anyone fails to turn it off. Should the system turn off inappropriately users may turn it back on with the AMX touch panel although there will be a delay while the system resets.

Notes on Computer Usage

Upon power up, the computer will respond with “Do a complete software reload [Y/N]]”. If you press Y within 8 seconds the computer will reload all software from the network and restore the computer to its original operating condition. The reload may take as long as 10 minutes and MUST NOT be interrupted. A system reload is recommended if you are having problems with operation of the computer or software. If you wait without entering any keystrokes, the computer will run Windows from the hard drive. The computer is set up with a base set of programs. WinINSTALL may be used to load additional programs. These programs will be lost if the system software is reloaded.
