Rooms 101 and 102 of Warren Weaver Hall are mirror images of one another and have identical A/V set ups. In the summer of 2007, new podiums and computers were installed, and wiring from the equipment to the projectors and speakers were upgraded. Please review the instructions below, which have been updated to reflect these changes. Note that there is no longer a video device, as the archaic VHS players have been removed. Instead, DVDs can be played on either computer, or on a laptop.
One can use the A/V equipment in rooms 101 and 102 without having a key if there are no needs beyond displaying what is on the computer, as everything can be done from the keyboard and mouse. If one needs access to audio controls, or the DVD drives on the computers, access to the interior of the cabinet is needed.
The keyboard and mouse are in a tray at the top of the cabinet, just below the work surface, which slides in and out of the podium. There is also a light on top of the podium, with a brightness control knob at its base, to illuminate the work surface if desired.
A key is required to access the interior of the cabinets in rooms 101 and 102. The same key works for both podiums. Each contains the following components:
- A PC running Windows XP and a Mac Mini running MAC OS.
- A Blackbox KVM switch that controls which input device is displayed on both the monitor and the projector.
- An audio amplifier that goes to the speakers in the room.
- Mixer Audio Controls: These allow you to control the volume for a particular piece of equipment.
- A storage drawer that contains some extra cables and the wireless microphones, as well as spare batteries for the microphones.
- MainSwitch: This main switch will turn off everything except the PC and Mac, which both MUST REMAIN ON AT ALL TIMES.
Using the Projectors
To power on and off the projector, use the switch on the wall next to the switch for raising and lowering the projectrion screen. Always select the COMP button for the computer. Alternatively, you may use the remote control that is affixed to the wall behind the podium. Either should work. The projectors need a few minutes to cool down and warm up. PLEASE TURN THE PROJECTOR OFF AFTER EACH SESSION.
Selecting the PC, Mac, or Laptop
The image that is displayed on the monitor is also displayed on the projector. You can use the keyboard to select between the PC, Mac, or laptop inputs using the following key sequences (do not hold down the number and control keys simultaneously):
- Control, then 1, then enter for the PC
- Control, then 2, then enter for the Mac
- Control, then 3, then enter for a laptop
You can also use the "+" and "-" buttons on the Blackbox switch. Be sure that the projector is set for the computer, rather than video, by selecting the COMP button on the remote or wall switch.
Connecting a Laptop
At the back of the work surface on top of the podium, beneath the monitor, are cables for connecting a laptop. Pull the VGA and network cables up and out to connect it to your laptop. In addition, there are power outlets, an audio cable, and a USB cable that can be connected to the laptop to enable use of the system keyboard and mouse.
Sending the Laptop Display to the Projector
Once the laptop is connected, type control, then 3, then return, as outlined above, to select the laptop as the input device. Depending on what type of laptop you have, you may need to adjust your display settings. For Windows based machines, on the Desktop, click with the right mouse button and select Properties. Under the Settings tab, locate the Display drop down menu. You may need to select Multiple Monitors and check Extend My Windows Desktop onto this Monitor. For Apple machines, adjust the Display settings under System Preferences. Under the Arrangements tab, click the Mirror Displays box.
The audio mixer inside the podium is used to adjust the volume levels for the various components. The mixer has knobs that are labeled for each of the components, including teh wireless microphones, which can be found in the storage drawer. To raise or lower the volume of the device you are using, simply to the correct knob accordingly. Please do not adjust the Master volume.
There are two wireless microphones located in the storage drawer. To use either, simply turn the power switch to the on position and adjust the volume on the mixer, as described above, using the knob labeled MIC. If the power light does not illuminate, replace the batteries with new ones, which should also be in the storage drawer.
When you are Finished:
- Turn off the projector using the POWER button on the wall switch or remote.
- If you are using the PC, log out by clicking on START / ShutDown / Close all programs and log on as a different user.
- If you are using a laptop, disconnect your laptop, and please return the cables to the cable well by threading them back in until only a few inches are out so the work surface can be left in an orderly state for the next user.
- Finally, lock up the cabinet.
|Nothing appears on the Monitor||The monitor or computers may be off. Make sure the monitor power is on, and that the Main power switch at the top of the cabinet's interior is in the on position. The light on the switch should be lit. Make sure that the computers are powered on as well.|
|I have a blue screen with a "no signal" message on the projector||You are getting the wrong input or no input. Be sure that the COMP button is pushed on the switch or remote. If you are using the PC or Mac, make sure that the right computer is selected by pressing, in sequence, control, then 1, then enter, or control, then 2, then enter. If you are using a laptop, you may need to adjust your display settings. Otherwise, type Control, then 3, then enter to select the laptop as the input device. Make sure the screen saver or power save are not on (push any key on the keyboard).|
|The projector doesn't turn on.||The projector bulb takes time to cool down and warm up. Do not push the power button repeatedly. The lights on the bottom of the projector turn from bright red (standby) to dim red (operating) when it is turned on via the wall-mounted power button. You will hear the fan start.|
