The Gefen 1:4 HDMI CAT5 DA

The Gefen 1:4 HDMI Over CAT5 Distribution Amplifi er allows you to distribute a
single HDMI video source remotely to as many as 4 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 1:4 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 4 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 1:4 HDMI CAT5 DA

• The 1:4 HDMI CAT5 DA unit is housed in a metal box for better RF shielding.

• An HDMI jumper cable (4 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.

• The DDC cable (for each pair or extensions) does not need to be run if the
source does not require HDCP or DDC. In this scenario, a single CAT-5, CAT5e
or CAT-6 cable for the video can be run. If DDC is still required while HDCP
is not, the use of an EDID storage device (part# EXT-DVI-EDIDN, EXT-DVI­EDIDP) can be used to transmit DDC information back to the source with this
single cable solution.

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

• Power supply for the receiver should not be connected unless the CAT-5, CAT­5e or CAT-6 cable runs exceed 180 feet, or you are using the single CAT-5,
CAT-5e or CAT-6 cable solution listed above.

• 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.
