The Gefen 1:8 HDMI CAT5 DA

The Gefen 1:8 HDMI Over CAT5 Distribution Ampliﬁer allows you to distribute a

single HDMI video source remotely to as many as 8 separate HDTV displays via

inexpensive and standard CAT5 cables as well as HDMI cables.

How It Works

Simply plug your master video source into the Gefen 1:8 HDMI Over CAT5 DA

sender unit, then run your cables to the remote locations.

If you are using CAT5 cables, pair up your cables with separately purchased

HDMI CAT5 DAR receivers at each video display.

If you are using HDMI cables, just attach up to 8 HDMI cables on the outputs and

connect the other ends to the displays.

After connection of cables, power up (or re-start) all equipment and you will have

effortless HDMI video duplication at all locations.

INTRODUCTION

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE 1:8 HDMI CAT5 DA

The• 1:8 HDMI CAT5 DA unit is housed in a metal box for better RF shielding.

An HDMI jumper cable (8 are included) must be connected from each of the• lower board outputs to each of the upper board inputs for proper extension

operation.

The maximum cable extension is 300 feet (91 meters) for video resolutions of• 1080i and below.

The maximum cable extension is 150 feet (45 meters) for video resolutions of• 1080p.

Display information (EDID) from the display attached to the HDMI CAT5 DAR• receiver, which is then routed to HDMI output port 1 (lower board), will be sent back

to the source. Therefore, all other displays connected to the receivers at the remote

locations must be capable of accepting the timings and resolutions of the display

that is attached to HDMI output port 1. It is recommended that the display with the

lowest native resolution be connected to HDMI output port 1. This is to ensure that

a compatible video signal will be able to be displayed on all connected monitors.

Shielded CAT6 with metal RJ-45 connectors is recommended to protect from• random ﬂashes caused by EMI.

Extensions under 130 feet can use Auto EQ (which is on by default).• Extensions over 130 feet will require you to manually EQ your signal (see page

5).

Each cable is recommended to be one continuous run from one end to the• other. While wall jacks and punch down blocks can be used, they may cause

degraded performance or unforeseen issues.

Do not use stranded or low/no skew cabling. Solid core cabling should be used• for maximum performance.

HDMI \ HDCP Compliant.•

The included power supply for the RECEIVER must be connected before the• connection of the CAT-5 cables. Once the power LED is active on the receiver

the CAT-5 cables can then be connected.Always follow this initialization

procedure on the RECEIVER if power has to been cycled due to a power

outage or for troubleshooting purposes.

NOTE: If an image is not being shown on the display, please check all cabling for

proper connections and follow the steps outlined below and in the next section.

The 1:8 HDMI CAT5 DA and HDMI CAT5 DAR receivers have built-in auto

equalization that will automatically tune out any unwanted video noise. This

feature is reliable with premium cable runs up to a maximum of 130 feet. It may

be necessary to disable this feature if there is either no video being displayed on

initial start-up, there is video noise in the image, or the cable run exceeds 130

feet. First, verify that all the proper connections have been made and that all

devices are powered on before attempting to disable auto equalization. Please

follow the section on the next page to manually equalize the video signal.

1:8 HDMI CAT5 DA CONFIGURATION

CONNECTING AND OPERATING THE 1:8 HDMI CAT5 DA

MANUAL EQUALIZATION PROCEDURE

The HDMI CAT5 DAR receiver units have a set of dip switches located on the

underside of their casings. There is a piece of silver metallic tape that must be

removed to expose these dip switches. Each HDMI CAT5 DAR receiver carries

one bank of 4 dip switches. All dip switches on the HDMI CAT5 DAR receiving

units are used in this procedure. Dip switches 1 relates to the Auto Equalization

function, while dip switches 3 and 4 control the boost strength from the 1:8

HDMI CAT5 sending unit. By default, all dip switches on the HDMI CAT5 DAR

should be in the OFF position. To turn off auto equalization, turn dip switch 1 on

the receiving units to the ON position (Auto EQ off). With these settings, please

follow the steps below to equalize the picture.

Insert a small ﬂat head tool into the trim pot on the receiver unit.1.

Turn the trim pot in a clockwise fashion until it comes to a stop. Do not force2. the trim pot beyond this point. Doing so may render the trim pot useless.

Slowly turn the trim pot counter-clockwise in millimeter increments until the3. image stabilizes and all video noise disappears.

Carefully remove the adjustment tool.4.

NOTE: If your cable run is beyond 130 feet, or the steps above do not produce

any video, it may be necessary to increase the boost from the sending unit. Use

the chart below to increase the senders boost strength by changing the HDMI

CAT5 DAR receiver’s dip switches. Once a new boost setting is set, repeat steps

1 through 4 from above. The required boost setting will largely be dependant

on the quality and length of cabling. Experiment with all boost settings until the

image stabilizes and all video noise has been eliminated.
