4X1 DVI DL SWITCHER REMOTE DESCRIPTION LED Indicator Input Selection Buttons The RMT-4IR remote control will allow the user to select which of 4 DVI sources will be displayed. Please use the information below when selecting the desired source for output to a display or other DVI video receiving device. RMT-4IR Button DVI Source...
4X1 DVI DL SWITCHER REMOTE INSTALLATION To use the RMT-4IR remote, remove the battery cover on the back of the remote to reveal the battery compartment. Insert the included battery into the open battery slot. The positive (+) side should be facing up. Ensure that both DIP (Dual Inline Package) switches are in the OFF position.

The other DIP switch (8-switch) is reserved for Gefen use only. DIP Switches 1 and 2 on the RMT-4IR directly correspond to DIP Switches 1 and 2 on the 4x1 DVI DL Switcher.
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.

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.
DL (DUAL LINK) ONLY MODES DL (Dual Link) Only Modes The 8-position DIP switch bank located on the underside of the 4x1 DVI DL Switcher can be used to set each individual input to work in a Dual Link Only mode.
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.
