INTRODUCTION

Thank you for purchasing the 4x4 HDTV KVM Matrix.
The 4x4 HDTV KVM Matrix switches four DVI sources to any four DVI displays.
Now you can easily switch four cross-platform computers to four digital displays. Our 4x4

HDTV KVM Matrix provides a simple, reliable and highly effective method of creating
multiple computer workstations, with each workstation capable of accessing any one of
the computers or sources at any time by remote control. You also have the option of
setting up the four stations locally or extending them with a Gefen extender. When used
with computers, USB and Audio Matrix control signals follow the DVI input for optimal
control. The 4x4 HDTV KVM Matrix also supports the connection of HDCP compliant
sources and displays.

Note: The switching is done by using either the RMT-16-IR remote control or through the
RS232 port. The 4x4 HDTV KVM Matrix is rack mountable. Any HDTV with HDMI
inputs can be connected to the DVI outputs of the matrix by using a DVI to HDMI adapter
if the cable used is HDMI.

Controlling the 4x4 HDTV KVM Matrix using the RMT16-IR:

Pressing Buttons... Switches...

1-4 Display 1 to view Source 1, 2, 3, or 4
5-8 Display 2 to view Source 1, 2, 3, or 4

9-12 Display 3 to view Source 1, 2, 3, or 4

13-16 Display 4 to view Source 1, 2, 3, or 4

*Note for computers connected to the 4x4 HDTV KVM Matrix - When your
computer boots up, it looks for an EDID (extended display identifi cation data) from
the display to tell it what monitor is connected and what resolution to output. During
boot up of the computer 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.

RMT16-IR INSTALLATION

1. Remove battery cover from the back of the RMT16-IR remote.

2. Verify that dip switches 1 & 2 are in the down (OFF) position.

3. Insert the battery, hold 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 RMT16-IR remote by pressing ONLY one button at a time. The indicator light
on the remote will fl ash once each time you press a button. WARNING: Do not press
multiple buttons simultaneously and do NOT press buttons rapidly. These actions will
cause the remote to reset and steps 1-4 will have to be repeated.

Note: The RMT16-IR ships with two batteries. One battery is required for operation, the
second battery is complimentary.

DIP SWITCH GUIDELINES

DIP SWITCH

EDID GUIDE

Extended display identifi cation data (EDID) is a data structure provided by a display to
describe its capabilities to any source that asks for it. The EDID includes manufacturer
name, product type, timings supported by the display, display size, luminance data, (for
digital displays only) pixel mapping data, supported audio channels and formats. This
information is used by the source to cater its output to resolutions and audio formats
that are supported by the display.

Additional EDID modes are available and confi gured using a combination of dip
switches 1, 2, and 5. Please refer below for the different EDID modes.

To access the Dip Switches, remove all screws from the bottom and sides of the
Gefen unit. Remove the hex screw heads from each side of the RS-232 and DVI ports.
Carefully slide the unit apart. The 8 Bank of Dip Switches are located on the main PCB.
Once adjustments are complete, slide the unit back together and replace all removed
screws.

EDID Mode 0 (Switch 1=OFF Switch2=OFF Switch5=ON)

-EDID is copied from the fi rst HDMI port
EDID Mode 1 (Switch 1=ON Switch2=OFF Switch5=ON)

-Same as Mode 0 and adds basic audio support
EDID Mode 2 (Switch 1=OFF Switch2=ON Switch5=ON)

-Same as Mode 0 and adds full audio support
EDID Mode 3 (Switch 1=ON Switch2=ON Switch5=OFF)

-EDID is generated based on the common video and audio features of all of the
connected devices

EDID Mode 4 (Switch 1=OFF Switch2=ON Switch5=OFF)

-Same as Mode 3 and adds basic audio support
EDID Mode 5 (Switch 1=ON Switch2=OFF Switch5=OFF)

-Same as Mode 3 and adds full audio support
EDID Mode 6 (Switch 1=OFF Switch2=OFF Switch5=OFF) DEFAULT

-EDID is generated based on the common video features of all of the connected
devices and the combined audio features of all of the connected devices

IR CODES

In the event of IR confl icts, please do the following:

1. Remove the battery cover from the back of the RMT16-IR remote.

2. Locate the Dip Switches above the batteries

3. Switch the Dip Switches on the RMT16-IR to any of the combinations pictured below.

4. Dip Switches 1 and 2 in the RMT16-IR correspond with Dip Switches 3 and 4 inside
the 4x4 HDTV KVM Matrix respectively. Switch the switches inside the 4x4 HDTV KVM
Matrix to match the same Remote Channel as the RMT16-IR. The 4x4 HDTV KVM
Matrix is now set to a new IR Code.

interface. For any of these modes to be successfully written to the EEPROM, all Dip
Switches must be in the OFF position.

TERMINOLOGY

DDC

Short form for Display Data Channel. It is a VESA standard for communication between
a monitor and a video adapter. Using DDC, a monitor can inform the video card about its
properties, such as maximum resolution and color depth. The video card can then use
this information to ensure that the user is presented with valid options for confi guring the
display.

DDWG

Digital Display Working Group DDWG are the creators of the DVI specifi cation.

DVI

Digital Visual Interface. Connection standard developed by Intel for connecting computers
to digital monitors such as fl at panels and DLP projectors. A consumer electronics version,
not necessarily compatible with the PC version, is used as a connection standard for HDTV
tuners and displays. Transmits an uncompressed digital signal to the display. The latter
version uses HDCP copy protection to prevent unauthorized copying.

HDCP

High-Bandwidth Digital Content Protection. Created by Intel, HDCP is used with HDTV
signals over DVI and HDMI connections and on D-Theater D-VHS recordings to prevent
unauthorized duplication of copy written material.

HDMI

The High-Defi nition Multi-media Interface (HDMI) is an industry-supported, uncompressed,
all-digital audio/video interface. HDMI provides an interface between any compatible digital
audio/video source, such as a set-top box, DVD player, and A/V receiver and a compatible
digital audio and/or video monitor, such as a digital television (DTV).

HDTV

High-Defi nition T elevision. The high-resolution subset of our DTV system. The A TSC defi nes
HDTV as a 16:9 image with twice the horizontal and vertical resolution of our existing system,
accompanied by 5.1 channels of Dolby Digital audio. The CEA defi nes HDTV as an image
with 720 progressive or 1080 interlaced active (top to bottom) scan lines. 1280:720p and
1920:1080i are typically accepted as high-defi nition scan rates.

RS-232

Recommended Standard 232. This is the de facto standard for communication through PC
serial ports. It can refer to cables and ports that support the RS232 standard.

VESA

Video Electronic Standards Association, a consortium of manufacturers formed to establish
and maintain industry wide standards for video cards and monitors. VESA was instrumental
in the introduction of the Super VGA and Extended VGA video graphics standards with
a refresh rate of 70 Hz, minimizing fl icker and helping to reduce user eyestrain and
fatigue.
