INTRODUCTION
Congratulations on your purchase of the GefenPRO 8x8 DVI Dual Link Matrix
with Push Button Controls. 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 build-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 Dual Link Matrix with Push Button Controls
The GefenPRO 8x8 DVI Dual Link Matrix with Push Button Controls provides
a professional-grade solution to route up to eight DVI sources to any eight DVI
displays. Dual link resolutions up to 3840x2400 are supported. The front panel
display shows the current routing status and the front panel push buttons are
used to manage local source routing. Four methods are available for controlling
the GefenPRO 8x8 DVI Dual Link Matrix with Push Button Controls: front panel
push buttons, IR remote, RS-232 interface, or using IP control with the built-in
Web interface.
How It Works
Connect up to eight DVI source devices to the GefenPRO 8x8 DVI Dual Link
Matrix with Push Button Controls using the supplied DVI cables. Connect up to
eight monitors to the DVI outputs. Plug in the power cord and apply power to the
Matrix. The DVI sources will be routed according to the current routing selection.
NOTE:

OPERATION NOTES
2
READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE GEFENPRO 8X8 DVI DUAL LINK MATRIX WITH
PUSH BUTTON CONTROLS
• The GefenPRO 8x8 DVI Dual Link Matrix with Push Button Controls only
supports DVI-D.
• Before connect a computer to the DVI input, make sure to disable the 5V
on the DVI input. Otherwise, the video card on the computer may become
damaged.
• The 8x8 DVI Dual Link Matrix with Push Button Controls does not support
HDCP content.
• When the Matrix is used for the rst time, make sure that a DVI monitor is
powered and connected to one of the DVI outputs on the 8x8 DVI Dual Link
Matrix with Push Button Controls before applying power. By default, the
Local EDID is read from the connected monitor and is copied to all 8 DVI
inputs once the Matrix has been turned on. If a monitor is not detected by
the Matrix at power-on, a default (internal) EDID of 640x480 will be used.
This functionality can be disabled using the Secure Local EDID function
through RS-232 control. See page 35 for more information.
• There is no internal scaling in the 8x8 DVI Dual Link Matrix with Push Button
Controls. Each monitor attached to the Matrix must be able to display the
resolutions output by the source device(s). For maximum compatibility it is
recommended that only one common resolution be used by each source
device.
• Advanced EDID features are accessible through the RS-232 serial command
set or using IP Control.
• The Gefen Firmware Upgrade Tool is a free downloadable application
from Gefen that provides automatic download and installation of rmware
upgrades for this product.
IMPORTANT: If the unit is installed in a closed or multi-rack
assembly, do not block the ventilation holes of the enclosure.
