Thank you for purchasing the new CAT5•9500HD series by Gefen, Inc.
The CAT5•9500HD by Gefen allows users the benefits of extending DVI, USB 1.1, PS/2,
RS232, and audio signals beyond the desktop. In a growing number of applications,
broadcast stations and production facilities there is a 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•9500HD series can be used to extend computers with noisy fans, printers, and
harddrives.Withthe potentialto coverthe distanceof 200feet, industrystandard Category
5e(CAT-5e)cables areusedfor theextensionofallthe devices.Onecan connectadditional
CAT5•9500HD series to the same computer, allowing access to the same computer from
other locations up to 200 feet apart.
Lengths and Distances Supported:
Up to 200 Feet....................................................................................1280x1024 @ 60Hz
Up to 150 Feet....................................................................................1920x1200 @ 60Hz
CONTENTS
The CAT5•9500HD system consists of:
(1) CAT5•9500HDS sender unit
(1) CAT5•9500HDR receiver unit
(2) 5VDC power supply
(1) DVI cable (6FT)
(2) PS/2 cable (6FT)
(1) Audio cables (6FT)

(1) User Manual
HOW IT WORKS
Inits most basicapplication, theCAT5•9500HDS senderunitresides nextto thecomputer.
Supplied with the system, DVI, USB 1.1, PS/2, and audio cables connect the computer to
the CAT5•9500HDS sender unit.
The CAT5•9500HDR receiver unit are placed next to the monitors and keyboard, mouse,
speakers, and RS232 devices, at the remote location. The monitor, keyboard, mouse, and
other devices are connected to the CAT5•9500HDR similar to the way they are connected
to the back of the computer (PC or Macintosh).

READ THESE NOTES BEFORE INSTALLING
OR OPERATING THE CAT5•9500HD SYSTEM
• Use industry standard Category 5e (CAT-5e) cable to operate the CAT5•9500HD
system.
• Please connect all the cables between the computer and the CAT5•9500HDS before
power up the CAT5•9500HDS unit.
• The CAT5•9500HD units are housed in a metal box for better RF shielding.

How to Connect the CAT5•9500HD Extender to your devices
1 Connect the supplied cables from the computer outputs into the CAT5•9500HD Sender
unit inputs. Only the peripherals being extended need to be connected.
2Connect the cable from your display (monitor or projector) into the DVI out of the
CAT5•9500HD Receiver unit.
3 Connect the cables from your peripherals into their respective outputs on the
CAT5•9500HD Receiver unit.
4 Connect two CAT-5e cables for video and USB extension on the CAT-5 Video and
CAT-5 DDC channel. Two CAT-5e cables are required for video extension.
5 Connect one CAT-5e cable for audio extension and another CAT-5e for PS/2 and
RS-232 extension.
6 Plug the 5VDC power supplies into the CAT5•9500HD Sender and Receiver unit.

SERVICE SWITCH USAGE GUIDE
9
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 configurations that will equalize the signal to best match
the conditions in your setup. For the CAT5•9500HD, 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

No Boost OFF 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 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 samewiththe DDCports.Test tomake suretheunits areworking withshort CAT-5e
cables 15-20 feet. You can also make sure you have the correct boost setting configured
(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 aADC to DVIAdapter otherwise damage to your
video card may result.
How can I fix an occasionally flickering or flashing 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.
Why is there a green or pink tint to my picture?
A tint of green or pink in the picture is a result of incorrect colorspace being transmitted.
This can be resolved by recycling power on your devices including the extender. If this
does not help, the DDC data containing the colorspace is not being transmitted correctly
due to loss in the CAT5 cable, try replacing the DDC cable.
Why is the USB dropping out every so often?
The USB bus is inherently not a very reliable system. Drop outs occur on occasion but if
it is happening quite often, then interference along the DDC line that is also transmitting
USB is causing the problem. Try using a shielded CAT-5e cable on this line instead.
I can’t seem to get my RS-232 devices to detect and connect, what’s wrong?
The CAT5-9500HD system only extends the Tx and Rx lines of RS232. If you need full
RS232 extension of every line, you will need the standalone RS232 Extender units.
Can I run the CAT-5 cable through a patch bay?
No, the signal will not transmit reliably

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 defines specific electrical properties
of the wire, but it is most commonly known as being rated for its Ethernet capability of 100
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 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 configuring the
display
DDWG
Digital Display Working Group DDWG are the creators of the DVI specification.
DVI
Digital Visual Interface. Connection standard developed by Intel for connecting computers
to digital monitors such as flat panels and DLP projectors.Aconsumer electronics version,
notnecessarily compatiblewith thePC version,is usedas aconnection standardfor HDTV
tuners and displays. Transmits an uncompressed digital signal to the display. The latter
version uses HDCP copy protection to prevent unauthorized copying

a refresh rate of 70 Hz, minimizing flicker and helping to reduce user eyestrain and
fatigue.
PS/2
Aport 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.
