INTRODUCTION  
Congratulations on your purchase of the 8x8 DVI KVM Dual Link Matrix. Your  
complete satisfaction is very important to us.  
GefenPRO  
In the realm of video distribution, certain features are invaluable in a commercial  
or broadcast environment. Accommodations such as a built-in power supply  
and at black rack-mount enclosures set GefenPRO apart from our traditional  
products. Complex distribution units allow for professional DVI, 3G-SDI, and  
HDMI signals to be routed and converted easily and seamlessly, while being  
backed up by a renowned and dependable technical support team. Gefen invites  
you to explore the GefenPRO product line and hopes that you nd the solution  
that ts your needs.  
The GefenPRO 8x8 DVI KVM Dual Link Matrix  
Easily switch eight cross-platform DVI Dual Link computers to eight DVI Dual  
Link displays with our 8x8 DVI KVM Dual Link Matrix. This product provides a  
simple, reliable and highly effective method of creating multiple computer work-  
stations, with each workstation capable of accessing any one of the computers  
or sources at any time by remote control. Eight stations can be set up locally or  
extended with a Gefen extender. When used with computers, USB and Audio  
matrix control signals follow the DVI Dual Link input for organized signal routing.  
How It Works  
The 8x8 DVI KVM Dual Link Matrix has eight Dual Link DVI inputs and eight Dual  
Link DVI outputs. Simply connect eight computers’ DVI Dual Link video ports  
to the Matrix’s inputs, then connect eight DVI Dual Link displays to the Matrix’s  
outputs. USB keyboard and mouse signals and analog audio, once connected,  
follow the selected DVI Dual Link input for each computer.

OPERATION NOTES  
READ THESE NOTES BEFORE INSTALLING OR  
OPERATING THE 8X8 DVI KVM DUAL LINK MATRIX  
The 8x8 DVI KVM Dual Link Matrix will not pass HDCP content.  
There is no internal scaling in the 8x8 DVI KVM Dual Link Matrix. All of the  
attached monitors must be able to display the resolutions output by the  
source devices. For maximum compatibility it is recommended that only one  
compatible/common resolution be used by all of the source devices.  
Advanced EDID features and IP conguration features are accessible via the  
RS-232 serial communication port. See page 16 for more information.  
Routing and EDID features can be accessed via a web browser using the IP  
control feature, built into the 8x8 DVI KVM Dual Link Matrix.  
IMPORTANT: If the unit is installed in a closed or multi-rack assembly, do  
not block the ventilation holes of the enclosure.

IR REMOTE INSTALLATION  
Installing the RMT-16IR Battery  
1. Remove the battery cover on the back of the IR Remote Control unit.  
2. Insert the included battery into the open battery slot. The positive (+) side of  
the battery should be facing up.  
3. Replace the battery cover.  
The Remote Control unit ships with two batteries. One battery is required for  
operation and the other battery is a spare.  
Empty Battery Slot  
CAUTION: Risk of explosion if battery is replaced by an incorrect  
type. Dispose of used batteries according to the instructions.

IR REMOTE CONFIGURATION  
Setting the IR Remote Control Channel  
In the event that IR commands from other remote controls interfere with the  
supplied IR Remote Control unit, changing the IR Remote Control’s IR channel  
will x the problem. The IR Remote Control unit has a bank of DIP switches used  
for setting the IR channel.  
The DIP switch bank is located underneath the battery cover.

It is important that the IR channel on the Remote Control unit, matches the  
IR channel set on the 8x8 DVI KVM Dual Link Matrix. For example, if both  
DIP switches on the IR Remote Control unit are set to IR channel 0 (both DIP  
switches down), then the 8x8 DVI KVM Dual Link Matrix must also be set to IR  
channel 0. See page 28 on how to change the IR channel on the 8x8 DVI KVM  
Dual Link Matrix.

Routing Sources using the IR Remote Control unit  
Issuing a routing command is a two step process. The rst step is to select the  
monitor where the source will be routed. The second step is to select the source.  
Example 1  
Route the source device connected to In 7 to the monitor connected to Out 3.  
1. Press button 3 (monitor 3) on the IR remote control unit.  
2. Press button 7 (source 7) on the IR remote control unit.  
The source connected to In 7 will be routed to the monitor connected to Out 3.  
Example 2  
Route the source device connected to In 1 to the monitor connected to Out 1.  
1. Press button 1 (monitor 1) on the IR remote control unit.  
2. Press button 1 (source 1) on the IR remote control unit.  
The source connected to In 1 will be routed to the monitor connected to Out 1.

EDID MANAGEMENT  
EDID. What is it and what is it used for?  
Under normal circumstances, a source device (digital and analog) will require  
information about a connected device/monitor to assess what resolutions  
and features are available. The source can then tailor its output to send only  
resolutions and features that are compatible with the attached device/monitor.  
This information is called EDID (Extended Display Information Data) and a  
source device can only accept and read one EDID from a connected device/  
monitor. Likewise, the source an only output one resolution for use by a  
connected device/monitor.  
Why is EDID so important with the 8x8 DVI KVM Dual Link Matrix?  
The 8x8 DVI KVM Dual Link Matrix is a complex piece of technology that  
replicates and switches between multiple inputs and outputs. Each connected  
source device will require one EDID to read. EDID management is carefully  
handled by the 8x8 DVI KVM Dual Link Matrix to provide a single EDID for each  
source to read.  
What options do I have to manage the EDID in the 8x8 DVI KVM Dual Link  
Matrix?  
First, it is important to note that each source device can only output one video/  
audio signal type. This includes resolutions and timings. When multiple devices/  
monitors are used, such as with the 8x8 DVI KVM Dual Link Matrix, it is important  
to use devices/monitors that have similar or compatible resolutions and features.  
This will ensure that the single video/audio signal produced by the source device  
is accepted by all of the connected output devices/monitors.  
The user has the option, through utilization of the RS-232 serial interface, to  
choose how the unit will manage the EDID from multiple DVI devices/monitors.  
Therefore the user has some control over the resolutions and features that the  
source devices will output. The 8x8 DVI KVM Dual Link Matrix has a Local EDID  
management mode that will control how the EDID information is handled.  
How do I change EDID modes in the 8x8 DVI KVM Dual Link Matrix?  
EDID modes are managed via the RS-232 serial communications port. See page  
17 for more information on the RS-232 serial communication features.
