Chapter 3: Installation
3. Installation
•Before installation, power off all devices that will be connected to this system.
•Make sure that all devices you will connect are properly grounded.
•Place cables away from fluorescent lights, air conditioners, and machines that are likely to generate electrical noise.
NOTE: If no screen displays, follow these steps:
1.Make sure the device cables are correctly and firmly attached.
2.Set your display device’s input source as DVI.
3.Check the PC BIOS configuration for the video output settings.
4.Connect your computer to the display DIRECTLY to check if the video signal gets through. Installation Steps
1.Use a video cable (DVI) to connect the display to the video output port on the back of the switch. Plug a set of audio jacks from the speaker to the switch’s speaker port.
2.Use a video cable (DVI) to connect the source device to the video input port on the switch.
Use an audio cable to connect the speaker port from the input side of the switch to the corresponding output port on the source device.
3.Plug the power supply into the switch and power on the switch.
4.Turn on the display (monitor, projector, or TV) and then power on the source device(s).
5.If necessary, apply EDID Copy process to the unit.
NOTE: When each video source is powered on, make sure it has a display pointing to it for EDID communication. If a source does not have a display pointing to it, a video image might not display.
