Page 13: Rmt-4Ir Remote And 4X1 Kvm Switcher Configuration
RMT-4IR REMOTE AND 4X1 KVM SWITCHER CONFIGURATION How to Resolve IR Code Conflicts In the event that IR commands from other remote controls conflict 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 configuring the remote channel that both units use to communicate. These settings must exactly match each other for proper operation. -
Page 14: Edid Modes
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. - Page 15 EDID MODES EDID Modes The diagram below illustrates the 4-position DIP switch bank (containing 4 small white toggle switches as shown). The functions of the switches are as follows: DIP SWITCH Function IR Channel IR Channel EDID Mode 1 2 3 4 EDID Lock Mode Use DIP switch 3 to set the desired EDID mode.
