OPERATION NOTES & TROUBLESHOOTING
USB
If your USB stops functioning correctly, you can manually re-intialize the
USB hub in the switch by pushing twice on the channel select button that
corresponds with the channel that the switcher is pointed at, on the front of
the unit. This will cause the channel selected LED to blink once letting you
know that the internal USB hub has been re-initialized. To have the USB
re-initialize automatically every time you switch, look under the 4x1 DVI
Switcher and locate the blank sticker. Peel it off to reveal a bank of four dip
switches. Find the dip switch labeled “4” and fl ip it to the ON position. Now
every time you switch the hub will re-initialize itself.
Video
When turning on or rebooting your computers, the 4x1 DVI KVM Switcher
must be selected to the computer that is booting until the computer
completes the boot cycle. This step can be eliminated using the Gefen DVI
Detective. If you lose your picture when you switch between sources you will
need a DVI Detective.
