INTRODUCTION
Congratulations on your purchase of the 2:8 DVI DistributionAmplifier. The 2:8 DVI distri-
bution amplifier is an innovative solution for anyone with more complex computer system
requirements, like studios and presentation venues where multi-viewing is essential. The
2:8 DVI distribution amplifier accommodates various system scenarios. Most commonly,
two video sources (either DVI-equipped computer, DVD player or satellite set top box)
are connected to the distribution amplifier on one side. On the output side, eight video
outputs are available to be used in part or in full. Once the unit is connected and powered,
each source can be routed to multiple displays.All DVI displays are driven by the two DVI
sources with each source or computer capable of driving eight displays at one time. For
home theater applications, the unit is HDCP (high definition content protection) compliant,
making it effective for use with all DVI displays.
How it works:
Gefen’sex•tend•it2:8DVI distributionamplifierisan expandabledistributionhub thatsends
the same DVI graphics source to eight DVI based digital screens (flat panels or projec-
tors).It isa flexiblesolution thataccommodates multipleDVI displays.You canswitch from
source one and two via the RMT-2IR remote control. The 2:8 DVI distribution amplifier is
also equipped with an auto sensing feature to switch between whatever source is active.
When one source is inactive it will automatically switch to the active source.
The ex•tend•it 2:8 DVI distribution amplifier is connected with a DVI (male to male) cable
from the DVI graphic source to the distribution amplifier input. There are eight DVI out-
puts in each module. DVI output one is the primary connection and is used for the main
display. DVI output 2 thru 8 follow the main display. The 2:8 DVI distribution amplifiers is
using a unique DVI Bus™ technology to connect multiple amplifiers without sacrificing a
DVI output connection. The ninth output is an expansion output used to daisy chain an
additional 2:8 DVI Distribution Amplifier. The 2:8 DVI Distribution Amplifier is expandable
to 256 outputs (32 DVI DA’s).

READ THESE NOTES BEFORE INSTALLING
OR OPERATING THE 2:8 DVI DISTRIBUTION AMPLIFIER SYSTEM
• All the monitors connected to the 2:8 DVI DistributionAmplifier must be able to run at the
same native resolution. The 2:8 DVI DistributionAmplifier does not scale the video.
• The 2:8 DVI Distribution Amplifier units are housed in a metal box for better RF shield-
ing.
• You must connect the sources and displays prior to applying power to the unit.

How to open the 2x8 DVI Splitter:
To access the dip switches, first remove the all the hex nuts on the back of the unit (2 for
RS232 port). Remove the all Philips screws under the unit and the 4 screws on each
side of the unit. Now carefully remove the cover of the 2x8 DVI Splitter.

IR CODE CONFLICTS
How to Resolve IR Code Conflicts
There are matching pairs of dip switches underneath the 2x8 DVI DAunit and under the
remote battery cover. Switch 1 & 2 on the Remote and Switch 3 & 4 underneath the unit
are the matching switches. These switches need to be matched for the remote to
communicate with the switcher. There are 4 possible sets of IR codes and at least one of
these sets should be able to resolve any IR conflicts with other home theater devices.
