AIT has provided computer and video projector in the Institute classrooms and meeting rooms. Video projectors are also installed in CSIM laboratory.
Following instructions summarize the way to use the equipment.
NEVER change the connection between the video projector and the computer, this may result in electric shock that will damage more than Bt 100,000 worth of equipment.
A video switch and a empty video input cable allow you to connect a notebook to the projector, so you don't need to change any cable connection.
The lamp in video projectors has a short life duration (approximately two years of teaching) and is quite expensive. To save the lamp, please turn off the video projector after each class.
The computer installed in the laboratory has a double video output, some configuration needs to be made in order to display optimal image on both the LCD screen and the video projector.
The video card is configured so that both the LCD screen and the video projector display the same image. But the displaying possibilities of the LCD screen and video projector are different. You must choose either the video projector image is at optimal definition but the LCD screen is slightly distorded; or the LCD screen is at optimal definition but the video projector is slightly distorded.
4. Confirm that you want to keep the display settings.
Note that the image on the LCD screen is distorded, but the image on the video projector is correct.
After you have finished your presentation, you should revert to the setting with the only display on the screen.
You will notice that the LCD screen is back to a proper display, any distortion being gone.
The computers installed in CSIM classroom and meeting room are connected to CSIM network. You should use your Samba account to log in. Alternatively you can use the account name CSIM to login, with no password, but you will not have access to your network files.
Remember to logout after you are done teaching: anyone using the classroom computer would have access to your personnal files if you don't disconnect.
You don't need to turn-off the computer after each class. We will make sure the machine is turned off at night. This should save time in between class as there is no need to turn the computer on again.
We have installed a video switch in CSIM classroom, meeting room and laboratory.
The switch allows to select between two inputs to display on the projector.
One input is reserved for the computer in the room, and the other input is empty, it can be used to connect a notebook. You can select the input by pressing on the big translucid part on the top of the video switch, the yellow light that indicates what input is selected will then change from one input to the other.
Always use that empty cable to connect to the notebook: now there is no need to diconnect any equipment to connect a notebook.
The following diagram shows how the various video equipments are connected.
You can use the empty video connector to attach your notebook to the projector.
The video switch allows to select the source of the video, while the video spliter makes sure that the video signal goes to the monitor and to the video projector.
The video spliter we are using must have the monitor turned on before it can send the signal to the video projector.
