INTRODUCTION Congratulations on your purchase of the 4x1 DVI DL Switcher. Your complete satisfaction is very important to us. Gefen Gefen delivers innovative, progressive computer and electronics add-on solutions that harness integration, extension, distribution and conversion technologies.
OPERATION NOTES READ THESE NOTES BEFORE INSTALLING OR OPERATING THE GEFEN 4X1 DVI DL SWITCHER • The 4x1 DVI DL Switcher will take any of up to four (4) DVI dual-link or single-link resolution inputs and switch them, one at a time, to a DVI output device such as a display/monitor or projector. Resolutions can be up to 3840x2400. • The 4x1 DVI DL Switcher is housed in a metal box for better RF shielding.
FEATURES Features • Switches easily between any four DVI-SL or DVI DL sources • Maintains highest resolution dual link DVI • Supports resolutions up through 3840x2400 • EDID Storage and programming for best source/display compatibility • Extends the range of the video signal on the DVI outputs up to 50 feet • Discrete IR remote control included • Serial RS-232 port for switching input sources via automated control or PC • Supports DDWG standards for DVI monitors • Rack ears included Packa

PANEL DESCRIPTIONS 1 External IR Port For connection of external IR extension device such as the Gefen IR Extender (part # EXT-RMT-EXTIR). 2 IR Receiver Receives IR signal from the handheld Infrared remote control unit included with the product. 3 DVI Signal Status LEDs 1-4 Provide visual confirmation of the currently selected DVI input signal out of the four DVI input ports. 4 DVI Input Selector Push-button switch cycles the next DVI input 1-4 in a forward sequence starting again at 1.
CONNECTING AND OPERATING THE 4X1 DVI DL SWITCHER How to Connect the 4x1 DVI DL Switcher to your devices: 1. Connect user supplied DVI cables from the DVI sources into the 4x1 DVI Switcher’s Inputs. 2. Connect the cable from your display (monitor or projector) into the DVI Out of the 4x1 DVI DL Switcher. 3. Connect the 5V power supply, then plug it into the wall. Turn on the DVI display or projector first, then the video sources (computers).
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.
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. Replace the battery cover. The remote ships with 2 batteries. One battery is needed for operation and the other battery is complimentary.
4X1 REMOTE CONTROL AND 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 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 configuring the remote channel that the units use to communicate. These settings must exactly match each other for proper operation.
EDID NOTES 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 cater its output to create resolutions and/or features that are compatible with the attached device/display. This capability information is called EDID (Extended Display Identification Data).
EDID NOTES, CONT’D 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 1 IR Channel 1 2 3 4 2 IR Channel 3 EDID Mode 4 N/A Use DIP switch 3 to set the desired EDID mode. How to set the two EDID Modes: 1.
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. These modes should only be enabled if issues occur when using Dual Link sources and displays in the default 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. How do I use these features? These features were initially intended for utilization by custom installers in automated setups.
RS-232 SERIAL COMMUNICATION COMMANDS 1. REMOTE SWITCHING FUNCTION The Switcher can be told to route one of 4 inputs to the Display by sending a single ASCII character over RS-232 corresponding to the selected source. This character is known as the short-cut character. 1.1 SWITCHING SOURCES BY SHORT-CUT CHARACTER The ASCII character table below indicates which Switcher input will be routed to the output Display when the corresponding ASCII (numeric) character is typed.
RS-232 SERIAL COMMUNICATION COMMANDS, CONT’D 2. USING SHORT-CUT CHARACTERS TO CHANGE SETTINGS 2.1 HYPERTERMINALtm SETTINGS in Microsoft Windowstm First, please setup correct communications by performing these commands (as shown on the screen shot immediately below): File->Properties->Setting->ASCII Setup Also, please be sure to unmark the check box that says “Send line ends with line feeds.” 2.2 EXAMPLE -- CHANGE THE ROUTED SOURCE Now you are ready to route Display input sources.
RACK MOUNT INSTALLATION Rack mount ears are provided for installation of this unit into a 1U rack mount space. 1. 2. 3. 4. Locate the side screws on the unit. Remove the front 2 screws that are located closest to the front of the unit. Using the removed screws, screw the rack mounting bracket into the unit. Repeat the procedure on the opposite side of the unit.
