The Gefen HDMI CAT-5 MS Extreme
The HDMI CA T-5 MS Extreme Extender extends your HDTV display up to 300 feet
away from your HDTV source using two CAT-5 cables. It is equipped with HDMI
(high defi nition multimedia interface) connectors and is capable of supporting DVI
(digital visual interface) equipment when used with a HDMI to DVI Adapter, providing greater fl exibility and options when integrating several home theater compo-
nents.
How It Works
The HDMI CAT-5 Extreme-S sender unit sits next to your computer, set-top box or
DVD player source. Cables supplied with the HDMI CAT-5 MS Extreme connect
your DVI or HDMI source to the send unit. The HDMI CAT-5 Extreme-R receive
unit sits next to your HDTV display - up to 300 feet away . The display plugs into the
back of the HDMI CAT-5 MS Extreme-R receiver unit. Two CAT-5 cables connect
the sender and the receiver units to each other.
INTRODUCTION

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE HDMI CAT-5 MS EXTREME
• The HDMI CAT-5 MS Extreme units are housed in a metal box for better RF
shielding.
• Your CAT-5 cable should not exceed 300 feet.
• If you do not need DDC or HDCP data you can use a single CAT-5 cable for the
video only. The DDC will not be connected. (For further information, see our
Terminology section on page 11.) If HDCP is required, both CAT-5 cables must
be used between the sender and receiver units.
• If the source requires EDID present, you can use the Gefen HDMI Detective to
provide EDID information to your source but will not transmit HDCP.
• Shielded CAT-6 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 you are using one
CAT-5 or going over a distance of 200ft.
• Extensions over 130ft. require you to manually EQ your signal (see page 7).
• Extensions under 130ft. use Auto EQ (which is on by default) (see page 7).
• The extender is factory set to Auto EQ which will work for distances under 130 ft.
• This product features the option to force the output colorspace to RGB and/or use
a pre-programmed EDID. These features can be used to resolve specefi c user
issues or for troubleshooting purposes. Please see page 8 for more information.

AUTO EQUALIZATION
1. Connect the HDMI source to the HDMI CA T -5 MS Extreme sending unit’ s HDMI
input port using the supplied HDMI cable.
2. Connect the HDMI CAT-5 MS Extreme sending and receiving units together
using two user supplied CAT-5, CAT-5e or CAT-6 cables.
NOTE: If fi eld terminating network cable, please adhere to the TIA/EIA568B
specifi cation. Please see page 9 for more information.
3. Connect the display to the HDMI output port of the HDMI CAT-5 MS Extreme
receiving unit using a user supplied HDMI cable.
4. Plug the 5V DC power supply into the HDMI CA T-5 MS Extreme sending unit.
NOTE: In most scenarios, the 5V DC external power supply for the receiving
unit will not be required. Operational power is supplied by the sending unit via
the connected CAT-5, CAT-5e or CAT-6 cable. If the power LED indicator on the
receiving unit is not on, please check to make sure that the RJ-45 cables are not
crossed (DDC to video and video to DDC).
5. Power on the display.
6. Power on the source.
The HDMI CAT-5 MS Extreme has 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.
CONNECTING AND OPERA TING THE HDMI CA T -5 MS EXTREME

7
The sender and receiver units both have sets 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 unit carries a bank of 4 DIP switches.
Dip switches 1 and 2 on the sending unit and DIP switch 1 on the receiving unit are
used in this procedure. By default, all DIP switches on the receiving units should
be in the OFF position (Auto EQ On). DIP switch 2 on the sending unit should be in
the ON position (No Boost). To turn off auto equalization, turn DIP switch 1 on the
receiving unit to the ON position (Auto EQ off). With this setting please follow the
steps below to equalize the picture.
1. Insert a small fl at head tool into the trimpot on the receiver unit.
2. Turn the trimpot in a clockwise fashion until it comes to a stop. Do not force the
trim pot beyond this point. Doing so may break the trim pot.
3. Slowly turn the trimpot counter-clockwise in millimeter increments until the
image stabilizes and all video noise disappears.
4. Carefully remove the adjustment tool.
NOTE: If your cable run is beyond 130 feet, or the following steps do not produce
any video, it may be necessary to increase the boost from the sending unit. Use
the chart below to increase the boost by changing the sender DIP switches. Once
a new boost setting is set, repeat steps 1 through 4 from above.
Sender DIP Switch Settings
Setting Switch 1 Switch 2
No Boost (Default) OFF ON
Medium Boost OFF OFF
High Boost ON OFF
Not Used ON ON
Receiver DIP Switch Settings
Setting Switch 1 Switch 2
Manual EQ ON OFF
Auto EQ (Default) OFF OFF
Adjustment Guidelines:
1. Strong boost should not be used on stranded cables. Strong boosting will cause
pixels or no picture on these cables.
2. Using the wrong settings will not damage the units; it will either produce no image
or a noisy image.
3. To eliminate the possibility of cross talk and interference, cables must be
terminated with 568B scheduling. (See page 9 for details)
4. No Boost should be set when using Auto EQ.
SERVICE SWITCH USAGE GUIDE

FORCE RGB AND PRE-PROGRAMMED EDID FEATURES
DIP switch 1 on the 4-bank DIP switch located on the underside of receiver unit
enables and disables the automatic equalization function. Additional features can
be enabled by using the other DIP switches on this bank.
FORCING THE RGB COLORSPACE
In some cases, the output video may have a pink or green tint. This usually is
attributed to the output device (i.e. display) not supporting the colorspace being used
by the source device. All digital displays will handle the standard RGB colorspace.
DIP switch 2 can be enabled to force the output colorspace to RGB. If the input
colorspace is YCbCr, the colorspace will be converted to RBG prior to output on
the receiver unit.
USING THE PRE-PROGRAMMED EDID
In some cases it may be necessary to force an HDMI 1.2 EDID for troubleshooting
purposes. Enabling DIP switch 3 will force the use of a pre-programmed EDID to be
sent to the source instead of the connected output device (i.e. display). The EDID
specifi cs are listed below.

640x480 60Hz
720x480i/p 59.94/60Hz

TERMINOLOGY
CAT-5
Category 5 cable, commonly known as Cat 5, is an unshielded twisted pair type
cable designed for high signal integrity . The actual standard defi nes specifi c electrical
properties of the wire, but it is most commonly known as being rated for its Ethernet
capability of 100 Mbit/s. Its specifi c standard designation is EIA/TIA-568. Cat 5 cable
typically has three twists per inch of each twisted pair of 24 gauge copper wires within
the cable.
CAT-5e
Similar to Cat 5 cable, but is enhanced to support speeds of up to 1000 Megabits per
second.
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. A digital video standard established by DDWG, which was
designed to carry uncompressed digital video signals to a display.
HDMI
The High-Definition 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).
HDCP
High-Bandwidth Digital Content Protection. Created by Intel, HDCP is used with HDTV
signals over HDMI and HDMI connections and on D-Theater D-VHS recordings to
prevent unauthorized duplication of copy written material.
HDTV
High-Defi nition Television. The high-resolution subset of our DTV system. The ATSC
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.
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.
