OR OPERATING THE CAT5•5500HD SYSTEM
* The CAT5•5500HD units are housed in a metal box for better RF shielding.
* Your CAT-5 cable should not exceed 200 feet.
OPERATION NOTES
INTRODUCTION
Thank you for purchasing the Gefen CAT5•5500HD series
The Gefen CAT5•5500HD allows users the benefits of extending dual DVI displays 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 CAT5•5500HD series can be used to extend computers with noisy fans, printers, hard
drives, scanners, cameras, keyboards, mouse, and any other USB. 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.

SERVICE SWITCH USAGE GUIDE
Gefen CAT5 Extreme 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 configurations that will equalize the signal to
best match the conditions in your setup. For the CAT5•5500HD, there are 1 set of
switches for each 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.)

No EQ (Default) OFF 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 8 for details)

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, what can I check?
First thing to check is make sure that the video CAT5 is linked to the other video CAT5 port
andthe samewith theDDC ports.Test tomake sure the units areworking withshort CAT-5e
cables 15-20 feet. You can also make sure you have the correct boost setting configured
(refer to page 10).
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
input connector will be a jumper that needs to be shorted to enable 5V to the input. This
shouldonly beenabled when using aADCto DVIAdapterotherwise damageto yourvideo
card may result.
How can I fix the flickering 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 10 for the different
combinations.
Can I run the CAT-5 cable through a patch bay?
No, the signal will not transmit reliably.
TROUBLESHOOTING GUIDE

CAT-5
Category 5 cable, commonly known as Cat 5, is an unshielded twisted pair type cable
designedforhigh signalintegrity.Theactualstandarddefinesspecificelectrical properties
ofthe wire,but it ismost commonlyknown asbeing ratedfor its Ethernetcapability of100
Mbit/s. Its specific 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 VESAstandard 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 configuring
the display
DDWG
Digital Display Working Group DDWG are the creators of the DVI specification.
DVI
DigitalVisualInterface.Connectionstandard developed byIntelfor connecting computers
todigitalmonitors suchasflatpanels and DLPprojectors.Aconsumerelectronicsversion,
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
UniversalSerialBus.Anexternal peripheralinterfacestandardforcommunicationbetween
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. VESAwas
instrumental in the introduction of the Super VGA and Extended VGA video graphics
standards with a refresh rate of 70 Hz, minimizing flicker 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.
