OPERATION NOTES
READ THESE NOTES BEFORE IN STALL ING
OR OPERATING THE CAT5•1500HD SYSTEM
* The CAT5•1500HD units are housed in a metal box for better RF shielding.
* In order to extend the full 50 meters, a high quality CAT5e or CAT6 cable is needed.
* CAT6 cable is suitable for high resolution at 50 meters.
* If using a ADC-DVI Adapter, the "5V to cable" jumper by the input connector on the
sender unit needs to be enabled.

INTRODUCTION
Thank you for purchasing the new CAT5•1500HD series by Gefen, Inc.
The CA T5•1500HD by Gefen allows users the benefi ts of extending a DVI display and USB
beyond the desktop. In a growing number of applications, broadcast stations and production facilities need to locate a computer remotely from the keyboard, mouse, and video
monitor. A CPU may need to be shared between several users, for example, or moved to
another room because of annoying fan noise.
The CA T5•1500HD series can be used to extend computers with noisy fans, printers, hard
drives, scanners, cameras, keyboards, mouse, and other USB devices. With the potential
to cover the distance of 150 feet, industry standard Category 5 (CAT-5) cables are used
for the extension of all the devices.

HOW IT WORKS
CONTENTS
The CAT5•1500HD system consists of:
--- (1) CAT5•1500HDS sender unit
--- (1) CAT5•1500HDR receiver unit
--- (2) 5V DC locking power supplies
--- (1) DVI cable M-M (6 FT)
--- (1) USB cable (6 FT)
--- (1) User's Manual
--- (1) Set of Rack Ears
HOW IT WORKS
The CAT5•1500HD sender unit sits next to your computer. The cables supplied with the
CAT5•1500HD connects your DVI source and USB to the send unit. The CAT5•1500HD
receiver unit sits next to your DVI display up to 150 feet away . The display and USB plug into
the back of the CA T5•1500HD receiver unit. T wo CA T-5 cables connect the CA T5•1500HDS and the CAT5•1500HD-R units to each other.

SERVICE SWITCH USAGE GUIDE
Gefen CAT5 HD products (sender and receiver) both contain a pair of service switches
(also called dip switches) located underneath the unit. These service switches are
used to select from sets of confi gurations that will equalize the signal to best match
the conditions in your setup. For the CAT5•1500HD, there is 1 set of switches for the
monitor under both the sender and receiver units. The switches are hidden beneath
black stickers. Each bank of dip switches have 4 switches. Switches 3 and 4 are not
used. (*Note: Adjustments should be done with sources and display on.)
Sender Dip Switch Settings
Setting Switch 1 Switch 2
No Boost OFF ON
Normal Boost (Default) OFF OFF
Strong Boost ON OFF
Undefi ned ON ON
Receiver Dip Switch Settings
Setting Switch 1 Switch 2
No EQ (Default) OFF OFF
EQ Setting 2 ON OFF
EQ Setting 3 OFF ON
Maximum EQ ON ON
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 7 for details)

TROUBLESHOOTING
Frequently Asked Questions
What kind of CAT-5e cable should I be using?
Solid core CAT-5e cable rated at 350 Mhz and terminated in 568a or 568b is the
minimum requirement. For resolutions greater than 1280x1024 or 1080i, Gefen
recommends solid CAT-6 cables.
I’m getting no video on the screens, how can I troubleshoot this problem?
First thing to check is make sure that the video CA T5 is linked to the other video CAT5 port
and the same with the DDC ports. Test to make sure the units are working with short CA T -5e
cables 15-20 feet. You can also make sure you have the correct boost setting confi gured
(refer to page 9).
I’m getting no video on the screens using ADC to DVI adapters, what is wrong?
ADC to DVI adapters remove the necessary 5V line that the extenders require on the input
to operate. To enable the 5V you will need to open up the sender unit. Next to each DVI/
HDMI input connector will be a jumper that needs to be shorted to enable 5V to the input.
This should only be enabled when using a ADC to DVI Adapter otherwise damage to your
video card may result.
How can I fi x the fl ickering picture?
Flickering or a blinking image is the result of a loss of sync between the display and the
source. Try lowering the resolution to see if that helps, if it does, the CAT-5 cables you
are using are unable to handle the bandwidth of the higher resolution and thus you are
losing sync. Try a shielded CAT-6 cable on the video line to reduce interference. You
can also try adjusting the service switches. Usually this is caused by EMI and a shielded
CAT-6 with metal RJ-45 connectors with the drain wire soldered to the connectors will
resolve the issue. Please refer to the service switch guide on page 9 for the different
combinations.
Can I run the CAT-5 cable through a patch bay?
This is not advised. The A/V signals will not be transmitted reliably to the Receiver unit
and thus the signal extension will fail.

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 1500 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. 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
USB
Universal Serial Bus. An external peripheral interface standard for communication between
a computer and external peripherals over a cable using bi-serial transmission.
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.
PS/2
A port type developed by IBM for the purpose of connecting a keyboard or mouse to a PC.
The PS/2 port has a mini DIN plug containing 6 pins. PS/2 ports are used so that the serial
port can be used by another device. The PS/2 port is often called the mouse port.
