4x4 DVI KVM
Matrix
USER MANUAL
INTRODUCTION
Thank you for purchasing the 4x4 DVI DL KVM Matrix.
Now you can easily switch four cross-platform DVI Dual Link computers to four DVI Dual
Link displays. Our 4x4 Dual Link DVI KVM Matrix provides a simple, reliable and highly
effective method of creating multiple computer workstations, with each workstation ca-
pable of accessing any one of the computers or sources at any time by remote control.
You also have the option of setting up the four stations locally or extending them with a
Gefen extender. When used with computers, USB 1.1 and Audio matrix control signals
follow the DVI Dual Link input for optimal control.
How It Works
The 4x4 DVI Dual Link KVM Matrix has four Dual Link DVI inputs and four Dual Link DVI
outputs.Yousimply connectyour fourcomputers' DVIDual Linkvideo portsto theSwitcher's
inputs, then connect your four DVI Dual Link displays to the Switcher's outputs. USB 1.1
keyboard and mouse signals and analog audio, once connected, follow the DVI Dual Link
switched input for each computer.

*Note for computers connected to the DVIKVM Matrix - When your computer boots
up, it looks for an EDID (extended display identification data) from the display to tell it
what monitor is connected and what resolution to output. During boot up of the comput-
er you should have ONLY one output selected to one input at a time so that the comput-
er gets the EDID of the display that is selected. If you have multiple outputs selected to
one computer, the computer will read the EDID of the last output selected to it. If all your
displays are the same, or all displays are
capable of running at the same resolution then this step does not matter.
You can also use a DVI Detective to eliminate the need to have that matrix selected to
the computer during bootup.

RMT16-IR INSTALLATION
The RMT-16-IR remote control will allow the user to select which source each of the
4 connected displays will be viewing. Each of the 4 displays are assigned a group of
4 buttons that correspond to the 4 source inputs. Please use the information below
when selecting the desired source for each display.

The 4x4 DVI DL KVM Matrix has a bank of 8 configuration DIP SWITCHES. These
switches are located underneath the unit. Peeling back the black metallic sticker on
the bottom of the 4x4 DVI DL KVM Matrix will reveal the Dip Switch bank. These
service switches are used for a number of configuration options. By default, all Dip
Switches are in the OFF position. Each setting is outlined below.
Switch 1 IR Remote Channel Configuration
Switch 2 IR Remote Channel Configuration
Switch 3 Automatic Link Selection \ Dual Link Only Mode
Switch 4 Not Used
Switch 5 Pre-Empahsis For Display Output 1
Switch 6 Pre-Empahsis For Display Output 2

Switch 8 Pre-Empahsis For Display Output 4
IR REMOTE CHANNEL CONFIGURATION
Dip Switches 1 and 2 relate to the IR remote control channel that is used by the 4x4 DVI
DL KVM Matrix and RMT-16-IR remote control. Dip Switch 1 and 2 on the 4x4 DVI DL
KVM Matrix must match Dip Switch 1 and 2 on the RMT-16-IR remote control. Please
view the table below to set the channel on 4x4 DVI DL KVM Matrix and IR remote
control. The remote channel for the RMT-16-IR is located underneath it’s battery
cover.

4X4 DVI DL KVM MATRIX CONFIGURATION
AUTOMATIC LINK SELECTION / DUAL LINK ONLY MODE
The 4x4 DVI DL Matrix has the ability to run both Single Link and Dual Link DVI sources.
There is a feature that will either automatically select the link mode, or lock the unit in Dual
Link mode. By default, Dip Switch 3 is in the OFF position (Automatic Link Selection).
Turning Dip Switch 3 to the ON position will lock the unit in Dual Link mode and will only
allow Dual Link signals to pass properly.
PRE-EMPHASIS
Pre-Emphasis is used to help extend a signal travel over a distance of cable. When a DVI
cable connected to a display is over a long cable, it is recommended that Pre-Emphasis
be enabled. Pre-emphasis is enabled by default on all display outputs. For short
cables, disable pre-emphasis on each output by turing it’s corresponding Dip Switch to
the ON position. If any type of extension device, such as a DVI CAT5 Extreme, is used
pre-emphasis must be disabled for proper operation.

RMT-MATRIX-444 INSTALLATION (OPTIONAL)
You can use up to 4 RMT-MATRIX-444 units to extend switching functionality to remote
locations. Each unit will allow the user to switch their one display between the 4 inputs
on the DVIKVM-444N. Follow these steps for each RMT-MATRIX-444 that will be used
in your setup.
1. Connect a CAT5/6 cable between the RMT-MATRIX-444 and one of the CAT5 ports
on the rear of the DVIKVM-444N. The ports are labeled as RMTA, B, C, and D and
correspond with DVI out ports 1, 2, 3, and 4.
2. Use the contact buttons on the RMT-MATRIX-444 to switch between the different
inputs connected to the DVIKVM-444N. Optionally, you can use a RMT-4IR (infrared
remote) in conjunction with the RMT-MATRIX-444 to switch inputs from a distance.
