Data Projector

Data projectors are installed on the ceiling in all DSI Tech-supported rooms. The data projector is controlled from the installed instructor computer. Use the computer's mouse to turn the projector on or off, select a display source, blank or un-blank the image, or adjust the volume.

Standard Instructor Computer

Each classroom has an computer for instruction purposes. Please see our Computer Setup for a full list of software available on the computers. You may install your own software, but the computer will be re-imaged weekly, returning the computer to a known state. For this reason, we recommend you keep your work in a cloud storage service (such as OneDrive) or on your office machine. If you require software for instruction that is not available on the machine on a regular basis, please try using Remote Desktop to connect to your office machine (or other machine that contains the software you need) or utilize the app virtualization services provided by the VMWare Horizon Client. Please contact us if you have a special use case.

Remember that a computer has its own volume control, so it may be necessary to un-mute or adjust the volume level on the computer as well as the data projector to get the desired sound level.

Multipurpose Camera

Each classroom is equipped with a small 2-in-1 multipurpose camera with a built-in microphone that can function as a document camera or webcam for software such as Zoom, Teams, Canvas Studio, etc.

To use the camera as a document camera, please turn on the projector and then launch the "IPEVO Visualizer" software from the classroom PC's Start Menu.

To use the camera as a webcam in Zoom, please select "IPEVO V4K" in the video and audio source selection drop-down menus.

NOTE: If your room is equipped with a wireless microphone, please select that input (shown below) for better audio quality.

Auxiliary Connections for Laptop Computer or Other Device

Using the connector panel on the room equipment rack, a separate computer or video source can be connected to the data projector.  

Most cables for this task are available at no charge from DSI Tech.  We can provide a VGA cable as well as various adapters that may be needed to adapt your device's connection to VGA.

To connect a notebook computer, use the connectors under "Computer 2" on the connector panel.  A VGA cable, shown below, is required.  Audio cables are optional.  

If you want to use sound on your computer, connect an audio cable from your computer’s headphone jack to the audio connectors in the same column on the connector plate.

If you do not see an image in a few seconds, you may need to tell your notebook computer to use its external monitor. The method for doing this varies between computer models.  Look on the notebook’s keyboard for "LCD/CRT" or a monitor icon to find the right keys to press. (The photos below represent keys used to activate the external monitor for a Dell notebook computer.)  

If your classroom is equipped with HDMI connections, the input panel will be at the top of the equipment rack, pictured below.

Some classrooms may have an HDMI cable routed through the instructor podium. 

Wireless Microphones

Wireless microphone systems are installed in the larger DSI Tech-supported rooms. In the past, instructors were required to check out a transmitter, but now each room will be equipped with a transmitter bodypack unit that is already synced to the same frequency as the receiver. Rooms equipped with a wireless microphone have a charging cradle containing the transmitter and microphone, as well as a spare rechargable battery. If a room is missing a transmitter, please contact us at 940-565-2691 to get it replaced.

The system can be used for voice amplification, as well as an input into lecture capture or web conferencing software. To use the wireless microphone as an audio input, please select "Microphone (Sound Blaster Audigy FX)" in the audio source selection drop-down menu.

To find which classrooms have a wireless microphone installed, please use our Search Classrooms tool.

NOTE: Rooms equipped with ceiling microphones mix both sources together, please see "Ceiling Microphones" below for the correct audio source.

Document Cameras

Most larger rooms are equipped with a desktop-mounted document camera, or visualizer, which allows the entire class to see a document or handwritten work on the projection screen. The visualizer is accessed by running software on the classroom PC, which can be launched by clicking on the "Visualizer" button on the on-screen projector remote (shown at the top of this webpage).

To find which classrooms have a desktop visualizer installed, please use our Search Classrooms tool.

PTZ/Instructor Camera

Most general-purpose rooms are equipped with a pan/tilt/zoom (PTZ) instructor camera. These cameras allow the front of the room to be captured on video and used in conferencing software such as Zoom, Teams, etc. or used to record a lecture in Canvas Studio or similar software. To control the camera, please use the "Camera" tab on the on-screen remote controls (shown below). Three presets ("Pre 1", "Pre 2", "Pre 3") are available to preset the camera shot for front-of-room wide shot, instructor close up, and the nearest whiteboard. 

To use the PTZ camera in conferencing software, please select "AV.io SDI Video" in the video source selection drop-down menu.

NOTE: In some rooms, the device name you need to select is "AVerMedia ExtremeCap SDI UVC".

Ceiling Microphones

Full-coverage ceiling microphones are available in a select number of rooms, which allow the entire class to be heard or recorded. To use the ceiling microphones in Zoom, please select "Echo Cancelling Speakerphone (TesiraForte)" in the audio source selection drop-down menu. 

NOTE: Rooms equipped with ceiling microphones will sound best on a call or video conference when paired with the wireless instructor microphone.
