Congratulations on your purchase of the 4x4 VGA Matrix. Your complete
satisfaction is very important to us.
Gefen
Gefen delivers innovative, progressive computer and electronics add-on solutions
that harness integration, extension, distribution and conversion technologies.
Gefen’s reliable, plug-and-play products supplement cross-platform computer
systems, professional audio/video environments and HDTV systems of all sizes

The Gefen 4x4 VGA Matrix
The Gefen 4x4 VGA Matrix offers flexibility and convenience by routing high-
quality VGA and Analog Audio from any of four VGA/audio sources to any of 4
VGA displays and audio devices.
The Gefen 4x4 VGA Matrix works with a wide variety of VGA sources such as
computers, security cameras and DVRs. Every source is accessible at any time
by any display by selecting it with the included IR remote, front panel buttons, or
RS-232 control.
How It Works
Connect up to four VGA and Analog Audio sources to the 4x4 VGA Matrix’s
inputs. Connect the Matrix’s VGAandAnalogAudio outputs to 4 VGAdisplays
and audio devices. Plug in the Matrix’s power supply. You may now switch VGA
and audio sources using the included IR remote, front panel buttons, or the built-
in RS-232 serial port. LED lights on the front panel show the currently selected
routes from the VGA sources to the VGA displays.
INTRODUCTION
READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 4X4 VGA MATRIX
• The 4x4 VGA Matrix does not transmit display information (EDID) to the
source. Standard VESA resolutions should be output by most computers
without the need of an EDID. If using a non-VESA standard resolution or
if EDID is needed, an EDID storage and relay device is necessary. Gefen
recommends the use of a DVI Detective (part# EXT-DVI-EDIDN) with two
VGA to DVI adapters.

1 Power LED
This LED indicator glows RED when power is connected properly and
sufficient power is being received by the Matrix.
2-5 Selected Input LED Indicators For Outputs 1-4
Each of the four output ports has an associated bank of 4 LED indicators that
shows which input source 1-4 is active for that output. The currently selected
input will be indicated by an active LED.
6 IR (Infrared) Receiver
This Receiver will accept commands for switching between VGAinput
devices using the included RMT-16IR remote control.
7 Reset Button
The Reset button momentarily interrupts power, rebooting the unit and
resetting operational settings to defaults. This feature is useful if the Matrix
somehow becomes unresponsive.
8-11 Input Selection Button For Outputs 1-4
This button will set the source (1-4) for the indicated output. Each labeled
output on the front panel has this button. Each press of this button will cycle
t hrough the four input sources that will be routed to that output.
12-15 Audio Output For Outputs 1-4
This 3.5mm mini-jack analog stereo output will accept a single amplified audio
device. There are four outputs, one for each VGAoutput.
16-19 Audio Inputs For Inputs 1-4
This 3.5mm mini-jack analog stereo input will accept a single audio source for
routing to the outputs. There are four inputs, one for each VGAinput.
20 RS-232 Serial Communications Port
This DB-9 serial communications port allows the Matrix to be controlled
remotely by computers or control automation devices. Remote control devices
send routing commands to the Matrix via this port in the form ofASCII
characters. Please see page 10 for RS-232 Configuration.
21-24 VGA Outputs 1-4
These outputs will accept a single VGAoutput device. Any of these four VGA
outputs can select and view one of the four VGA/Audio inputs.
25-28 VGA Inputs 1-4
These inputs will accept a single VGAsource device. Any of these four VGA
inputs can then be routed in any combination to the four VGAoutputs.
29 24V DC Power Receptacle
Connect the included 24V DC power supply between this port and an open
wall power receptacle.

1. Remove battery cover from the back of the RMT-16-IR remote (see picture
below).
2. Locate the DIP Switches and verify that DIP switches 1 & 2 are in the down
(OFF) position.
3. Insert the battery, holding the battery so that you can see the positive side facing
up. The side that is not marked must be facing down.
4. Test the RMT-16-IR remote by pressing ONLY one button at a time. The
indicator light on the remote will flash once each time you press a button.
WARNING: Do not press multiple buttons simultaneously and do NOT press buttons
rapidly. The remote will need to be reset and steps 1-4 will have to be repeated.
NOTE: The RMT-16-IR ships with two batteries. One battery is required for
