The Gefen 4x1 DVI KVM DL/SL Switcher
The rack-mountable Gefen 4x1 dual link/single link DVI KVM DL/SL Switcher offers an economical solution by eliminating the need to purchase many displays for each computer in a studio or lab situation. A plug-and-play solution that supports both Macintosh and IBM-PC computers, the 4x1 DVI KVM DL/SL Switcher shares one DVI display with up to four computers or other DVI video sources. A single USB 2.0 port, keyboard & mouse ports, and an analog audio jack are also switched. The switcher saves space on your desktop by eliminating a crowded workspace full of DVI monitors, keyboards & mice, and USB and audio cables. Switching of DVI sources is easy and reliable.
How It Works
The DVI monitor is connected to the 4x1 DVI KVM DL/SL Switcher’s output. Up to four DVI video/USB/Audio sources connect to the switcher’s inputs using included high quality DVI, USB and Audio cables. The included power supply is connected to the switcher via the locking power plug and then to a power outlet. The currently selected DVI video signal appears on the shared monitor. DVI Video sources (and optionally keyboards & mice, USB and audio cables) are selected/switched using the RMT-4IR remote control, RS-232 control, or the input selector push button on the front panel of the switcher.

RMT-4IR REMOTE AND 4X1 KVM SWITCHER CONFIGURA TION
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 operation.
The DIP Switch bank on the RMT-4IR is located underneath the battery cover. DIP Switch banks for the 4x1 DVI KVM DL/SL Switcher are located on the underside of the unit beneath a black piece of metallic tape. One DIP switch bank (4-switch) is for the adjustment of remote control frequencies and switch behavior. The other DIP switch (8-switch) is reserved for DL Only mode (page
12). Switches 1 and 2 on the RMT-4IR directly correspond to DIP Switches 1 and
2 on the 4x1 DVI KVM DL/SL Switcher. Only switches 1 and 2 (of 4 in that bank) are used for IR Code settings.

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 only accept and read one EDID data structure/record from a connected source device/display. Likewise, the source device can output only one video resolution to a connected device/ display.
The importance of EDID with regards to the 4x1 DVI KVM DL/SL Switcher
The 4x1 DVI KVM DL/SL Switcher handles multiple sources/inputs. Each connected source device must correctly read one EDID data structure in order to address its display device correctly. EDID management is carefully handled by the 4x1 DVI KVM DL/SL Switcher to insure that EDID is recorded and retransmitted properly, otherwise display of the input sources might not occur correctly (or at all).
Managing EDID with the 4x1 DVI KVM DL/SL Switcher
The 4x1 DVI KVM DL/SL Switcher uses 2 modes for routing EDID. They are:
1. When the local EDID Mode is ON, (factory default setting) the Switcher copies the EDID of the connected display to the local memory location as they are selected. Each device must fully “boot up” before you can select the next input. The connected device derives EDID information from the local memory location.
2. When the local EDID Mode is OFF, each time a new source device is selected, the Switcher connects EDID from the attached display to the currently selected input source.
Both modes are described in greater detail on the opposite page.
NOTE: The 4x1 DVI KVM DL/SL Switcher also features an EDID Lock Mode, allowing the EDID to be stored. See the following page for details.
How do I change EDID modes in the 4x1 DVI KVM DL/SL Switcher?
There is a bank of 4 DIP (Dual Inline Package) switches located on the main circuit board of the Switcher underneath a small piece of silver grey tape on the underside of the Switcher. When the sticker is removed, there will be two DIP switch banks visible, one with 4 switches and one with 8 switches. The 8-switch DIP switch bank is not used here (it is used for the DL (dual link) feature covered later on page 12.)

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
1 IR Channel
2 IR Channel
3 EDID Mode
1
Use DIP switch 3 to set the desired EDID mode. (UP is On) How to set the two EDID Modes:
1. Local EDID Mode ON (Switch 3 = OFF, FACTORY DEFAULT SETTING)
During power-on, the connected display’s EDID is copied to all four local EDID storage locations at once. EDID stored in local memory is then passed to all input sources.
The EDID stored in the local locations can be overwritten with another EDID from the following locations:
Built-in EDID memory bank (up to 7 EDID records can be stored)
EDID collected directly from the input display upon power-up.
2
3
4
4 EDID Lock Mode
2. Local EDID Mode OFF (Switch 3 = ON)
The DDC signal of the connected display is routed directly to each input source. Each time a new source device is selected, EDID is transmitted from the attached display to the currently selected input source. (This mode will successfully pass HDCP signals.)
3. EDID Lock Mode (DIP Switch 4 = ON)
Locks the last stored EDID, even if the unit is power-cycled. To store a new EDID, do the following:
1. Power-down the Switcher and set DIP Switch 4 to the OFF position.
2. Connect the display to the DVI output port then power-on the Switcher.
3. Set DIP Switch 4 to the ON position to lock the EDID.

DL (DUAL LINK) ONLY MODES
DL (Dual Link) Only Modes
The 8-position DIP switch bank located on the underside of the 4x1 DVI KVM DL/ SL 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.
DIP SWITCH Function DIP SWITCH Function
1 Input 1 Mode 5 N/A
2 Input 2 Mode 6 N/A
3 Input 3 Mode 7 N/A
4 Input 4 Mode 8 N/A
DL (Dual Link) and SL (Single Link) Mode (Switch=OFF) DEFAULT
This setting can be set individually for each input. This mode will allow the connection of both Dual Link and Single Link displays.
DL (Dual Link) Only Mode (Switch=ON)
This setting can be set individually for each input. This mode should be enabled if issues with the default occur with Dual Link displays.

RS-232 SERIAL CONTROL
What features are available via the RS-232 serial communications port?
The 4x1 DVI KVM DL/SL 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 be tested by using any Windows PC with a terminal emulation program such as Putty*. The next few pages will show you how.
What pins are used for communication with the 4x1 DVI KVM DL/SL Switcher?
Only pins 2 (Receive), 3 (Transmit), and 5 (Ground) are used for communication. A null-modem adapter should not be used with this Switcher.
