Congratulations on your purchase of the 4x4 HDMI™ Over CAT5 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
with hard-working solutions that are easy to implement and simple to operate.

The Gefen 4x4 HDMI™ Over CAT5 Matrix

The Gefen 4x4 HDMI™ CAT5 Matrix offers unprecedented fl exibility and con-
venience by routing high defi nition audio/video from any of four HDMI™ video
sources to any of 4 remote displays over inexpensive, standard CAT5 cabling.

Each remote display has a control box that allows the viewer to select any of the
4 video sources and control that source via an IR remote control as if the viewer
was standing in the room where the source originates.

Full High-Resolution HDTV signals are supported up to a resolution of 1080p at
a maximum distance of 150 feet and 1080i resolutions can be extended up to
300 feet. The Gefen 4x4 HDMI™ CAT5 Matrix works with HD-DVD players, TiVo
systems, HT PCs, and satellite set-top boxes that connect to an HDMI™ display.
Every source is accessible at all times by any display by selecting it with an IR
remote.

How It Works

You simply connect up to 4 local video sources to the CAT5-Matrix’s inputs. Then
run each of your CAT5 cables from the Matrix to the destination displays. At each
remote display, terminate the CAT5 cable run with a HDMI™ CAT5-MS Receiver
device. Connect each Receiver to a display and you’re all set.

INTRODUCTION

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE 4X4 HDMI™ OVER CAT5 MATRIX

To use the extender functionality of the • 4x4 HDMI™ Over CAT5 Matrix the
supplied 1 foot HDMI jumper cables must be used to connect the HDMI
output ports to the HDMI extension input ports. Please see page 11 for
details

Use two industry standard CAT-5, CAT-5e or CAT-6 cables to operate each •
of the 4x4 HDMI™ Over CAT5 Receivers. Gefen recommends CAT-6 cabling
for maximum performance.

For 1080i video, maximum extension is 300 feet (91 meters).•
For 1080p video, maximum extension is 150 feet (45 meters).•
IR repeater functionality is only from the receiving unit to the sending unit. IR •

data cannot be transmitted from the sending unit to the receiving unit.
When a display connects to a source being viewed by other displays, a short •

fl ash may appear momentarily on the displays already viewing that source.
This is normal operation as new handshakes for HDCP are being made.

Local displays that are not using the extension functionality of the 4x4 •
HDMI™ Over CAT5 Matrix can only switch their viewing source via the RS­232 Serial Control Interface. Please see page 18 for a list of commands and
instructions.

Matrix.

This example shows
the jumper connection
between HDMI output
port 1 and HDMI
extension input port

OPERATING THE 4X4 HDMI™ OVER CAT5 RECEIVER

To use the 4x4 HDMI™ Over CAT5 Receiver, the following connections must be
made:

A HDMI jumper cable is connected between the HDMI output port and the 1.
HDMI extension input port.

The DDC and Video CAT-5e cable must be connected between the 4x4 2.
HDMI™ Over CAT5 Matrix and the 4x4 HDMI™ Over CAT5 Receiver.

A HDMI display is connected to the 4x4 HDMI™ Over CAT5 Receiver.3.
The included power supply is connected to the 4x4 HDMI™ Over CAT5 4.

Receiver.

Once these connections are properly made, the 4x4 HDMI™ Over CAT5
Receiver can be used to select which HDMI source will be viewed on the
connected display. To select a HDMI source the direct input buttons located on
the top panel of the 4x4 HDMI™ Over CAT5 Receiver.

Button A selects HDMI Input 1
Button B selects HDMI Input 2
Button C selects HDMI Input 3
Button D selects HDMI Input 4

Switching can also be done using the included IR remote control or via the
RS-232 serial control interface.

NOTE: Switching of HDMI sources is limited to the one display that is connected
to a particular 4x4 HDMI™ Over CAT5 Receiver. For example, it is not possible
to switch a HDMI source on a display connected to HDMI output 2 with the
remote at the display location of HDMI output 1. Switching of any local displays
that are not being extended or are not using a 4x4 HDMI™ Over CAT5 Receiver
is limited to the RS-232 serial control interface from the 4x4 HDMI™ Over CAT5
Matrix.

IR Blaster Functionality

To control HDMI sources from the remote location, a optional IR blaster (Part#
EXT-2IREMIT) can be attached for each 4x4 HDMI™ Over CAT5 Receiver on
the 4x4 HDMI™ Over CAT5 Matrix. IR remote control commands can then be
relayed from each receiver to the device(s) connected to the blaster from the 4x4
HDMI™ Over CAT5 Matrix.

The 4x4 HDMI™ Over CAT5 Receiver contains a bank of 8 DIP SWITCHES.
These swiches are located underneath each unit. Peeling back the black metallic
sticker on the bottom of the 4x4 HDMI™ Over CAT5 Receiver will reveal the DIP
SWITCH bank. These service switches are used for a number of confi guration
options. By default, all Dip Switches are in the OFF position. Each setting is
outlined below.

Auto Equalization & Boost Setting

Auto equalization is enabled by default. This setting will compensate for variances
in cable skew and will help eliminate the video noise that is associated with it. This
feature will work reliably up to 130ft. Longer CA T-5e runs should have this feature
disabled. It is important to understand that the Boost Setting and Equalization are
used in conjunction with each other. The Auto-EQ feature will only function when the
unit has no boost applied.

To manually equalize the video signal, turn Dip Switch 1 to the ON position. This will
disable the auto equalization function and will allow the user to manually equalize the
signal. From here, the Boost Settings and Equalization can be manipulated to tune-in
an optimal video signal. Once Auto-EQ has been disabled, follow the steps on the
next page.

Dip Switches 2 and 3 relate to the IR remote control channel that is used by the
4x4 HDMI™ Over CAT5 Receiver and RMT-4IR remote control. Dip Switch 2
and 3 on the 4x4 HDMI™ Over CAT5 Receiver must match Dip Switch 1 and
2 on the RMT-4IR remote control. Each 4x4 HDMI™ Over CAT5 Receiver and
remote pair, should be set to a different channel so that no two units do receive
confl icting IR commands. Please view the table below to set the channel on
each of the 4x4 HDMI™ Over CAT5 Receiver units and IR remote controls. The
remote channel for the RMT-4IR is located underneath the battery cover.

Gefen has specifi cally engineered their products to work with the TIA/EIA-568-B
specifi cation. Please adhere to the table below when fi eld terminating cable for
use with Gefen products. Failure to do so may produce unexpected results and
reduced performance.

CAT-5, CAT-5e, and CAT-6 cabling comes in stranded and solid core types.
Gefen recommends using solid core cabling. CAT-6 cable is also recommended
for best results.

Each cable run must be one continuous run from one end to the other. No splices
or use of punch down blocks.

EDID DIP SWITCH GUIDELINES

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 port and
above each HDMI connector. 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.
