Supporting the Study Rooms (Big Screens)

Supporting the Study Rooms (Big Screens)


Study rooms contain multiple hardware devices working in conjunction with each other. The main elements are the workstation, the large screen display and the wireless keyboard. In order for the components to work together, the settings on each must be correct.

The Large Screen Display (tv) – The large screen's input must be set to “RGB-VIDEO”. This can be done either via remote control (located at the reference desk) or via the Buttons on the right-hand side of the display.  In order to set the input:

  1. Press the “INPUT” button on the side of the display.
  2. Using the “Volume UP/DOWN” buttons, scroll through the inputs until “RGB VIDEO” is selected.

The Workstation – The workstation is stored in a locked enclosure (big, wooden box) to the right side of the large TV screen.  There are ventilation ports (big open windows cut in the box).  You can reach the power button and power cord without having to open the cabinet, using these ports.  Even with the ports cut, the workstation sometimes radiates a large amount of heat within the enclosure and may sometimes freeze, or shut down prematurely.  You may need to restart the workstation, and remember- students are required to log into these workstations with their hostos login credentials.

Opening/ Saving Files- The workstations have a USB port that students can use, on a cable that protrudes out of the top of the enclosure. Alternatively, students should be able to reach their emails or online drive spaces (Google Drive/ Dropbox, etc.) from these workstations.

Students that require Sound - There are currently no speakers attached to the workstation as the neighboring rooms are used for archives work and teaching workshops. If a student wants to use sound, they may bring a laptop into the study room and use the electrical outlets available. Alternatively, If they have a laptop with video output and the appropriate cable (HDMI, for instance), they can project their laptop display on to the large screen and use the laptop's speakers for sound.

The Wireless Keyboard/MousePad Modules – This components consists of 2 parts: The Keyboard /Mousepad and the USB dongle.  The USB dongles are already inserted into the respective workstations locked inside the enclosure and are powered by the computer. The keyboard communicates with the dongle wirelessly and is powered by batteries. There is a power switch along the top edge.



  1. Display notifies user of “No Signal”
    1. Check that the Display INPUT is set to RGB Video: Press the INPUT button on right side of display and use the VOLUME UP/DOWN buttons to select “RGB VIDEO” as source.
    2. After the Input is set, make sure the workstation is on by pressing the power button which is reachable through the lower, larger ventilation port on the workstations enclosure.
  2. The Workstation appears to be on and the input on the TV is set correctly, but there is still no image.
    1. The computer can sometimes shut down or freeze, and pressing and holding the power button for 15 seconds will cut the power to the workstation.
    2. Pressing and holding the power button was unable to kill the power to the workstation. The power light is still on and the fan, hard drive can be heard. In this instance, the power to the workstation can be cut by reaching through the rear ventilation port and removing the plug from the rear of the workstation and reinserting it.
    3. Power up the workstation again making sure that the input is set correctly on the display.
  3. You can see the Workstation's interface on the display but it does not respond to any key presses or navigation movements on the mousepad.
    1. Check to make sure that the Keyboard is on.
    2. Make sure the keyboard is for the study room you are in. Each respective keyboard's connection is specific to the dongle in workstation they were sold with. Therefore, the Keyboard for Room B will not work for the workstation in room A and vice versa.
    3. Check the batteries in the keyboard to make sure they are fresh.
  4. Students report NO Sound coming from the workstations.
    1. For the time being, this is by design and there are surrounding classrooms and office that would be disrupted by high level of noise.  Students may bring in their own laptops for sound and use the electrical outlets in the study rooms.

*If for any reason the enclosure needs to be opened (such as a student accidentally dropping their flash drive in the top port of the enclosure), The IT assistant (room  A207J) has the key.
