4X1 REMOTE CONTROL AND 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 control channel will alleviate this issue. The RMT-4IR remote control and the 4x1 DVI DL Switcher both have banks of DIP (Dual Inline Package) Switches for confi guring the remote channel that the units use to communicate. These settings must exactly match each other for proper operation.

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

RS-232 SERIAL CONTROL INTERFACE What features are available via the RS-232 serial communications port? The 4x1 DVI DL Switcher can accept commands through the RS-232 serial communications port located on the rear panel. The current RS-232 control features are the ability to switch/route inputs to outputs without the RMT-4IR remote control. How do I use these features? These features were initially intended for utilization by custom installers in automated setups. However, these features can
