RMT-4IR REMOTE AND 4X1 KVM SWITCHER CONFIGURATION How to Resolve IR Code Confl icts In the event that IR commands from other remote controls confl ict with the supplied RMT-4IR remote control, changing the remote channel will alleviate this issue. The RMT-4IR remote control and the 4x1 DVI KVM DL/SL Switcher both have banks of DIP (Dual Inline Package) Switches for confi guring the remote channel that both units use to communicate. These settings must exactly match each other for proper operat

EDID MODES What is EDID and what is it used for? Under normal circumstances, an audio/video source device (digital or analog) will require information about a connected device/display to assess what resolutions and features (capabilities) are possible. The source device can then tailor its output to create resolutions and/or features that are compatible with the attached device/display. This capability information is called EDID (Extended Display Identifi cation Data). A source device can on
