CONNECTING AND OPERATING THE 4X1 DVI DL SWITCHER
How to Connect the 4x1 DVI DL Switcher to your devices:
1. Connect user supplied DVI cables from the DVI sources into the 4x1 DVI
Switcher’s Inputs.
2. Connect the cable from your display (monitor or projector) into the DVI Out
of the 4x1 DVI DL Switcher.
3. Connect the 5V power supply, then plug it into the wall. Turn on the DVI
display or projector fi rst, then the video sources (computers). Turn on
the 4x1 DVI DL Switcher by screwing its 5V DC power supply tip into the
receptacle in the rear of the chassis.
Note:
The Switcher retrieves device resolution and video timing capability
information called EDID from the display and feeds it to all connected input
sources. This mode of operation is called LOCAL EDID mode. It allows
a much faster setup time and improved operational stability since input
sources do not need to individually collect and store EDID on their own.
If some sources do not display correctly, you can individually confi gure each
input source and/or program custom EDIDs (such as standard compatible
resolutions) into the Switcher, or alternately set each input source to directly
read EDID from the display device (with the Local EDID Mode turned OFF).
These procedures are covered in detail on pages 10-11 along with EDID
concepts in general.
