(PC or MAC) to any four DVI digital displays with USB keyboard and mouse.
The 4x4 DVI Matrix switcher has four DVI inputs and four DVI outputs. Matrix input#1 and
the graphics port of Computer #1 connects using a male to male DVI cable. Computer #2

READ THESE NOTES BEFORE INSTALLING
OR OPERATING THE 4X4 DVI/HDTV MATRIX
• The 4x4 HDTV Matrix is the same as the 4x4 DVI Matrix, but the USB may or may not
be functional
• You should connect all the cables and power supply prior to connecting power to the
computers and 4x4 DVI Matrix
• When starting the computers the display needs to point to the source input
• The 4x4 DVI Matrix is housed in a metal box for better RF shielding.
• The 4x4 DVI Matrix works with all DVI and HDMI displays.
• HDCP operation works only with the first display that is selected to one input. If there is
more than one display connected to one input the first display switched to the source will
show properly, the other displays may not.

24VDC - Connect to 12-24VDC power supply.
Remote - 2 wire serial remote control
RMT4 - RJ45 connector connects to the ex•tend•it RMT-4 remote control. Each
RMT-4 controls one of the outputs by switching to one of the the inputs.
USB In - USB input from each source (computer).
USB Out - Connects to USB devices for the output.
HPD/5V - When switches 1,2,3, & 4 are in the UP position, it will make the HPD pin
(pin 16) active. When the second set of 1,2,3, & 4 switches under the +5v heading
are UP, it will output +5v to the DVI cable (pin 14). These switches should be in the
DOWN position unless you are using a fiber optic based DVI cable and the source
is not supplying +5v power on pin 14.
Caution: Setting the +5v dip switches in the ON position when a DVI source is
already outputting +5v may harm your DVI source.
DVI Input - Connects to computers or the HDTV source
E Select - EDGE select is set by dip switches from the back panel. For normal
operation, all four EDGE switches should be set to UP.
DVI Out - Connects to DVI displays

Booting up the computers - When your computer boots up it looks for an EDID
(extended display identification data) from the display to tell it what monitor is con-
nect and what resolution to output. During boot up of the computers you should
have ONLY one output selected to one input at a time so that the computer 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.
