INTRODUCTION  
Congratulations on your purchase of the CAT5•4000 Extender. Your complete  
satisfaction is very important to us.  
Gefen  
Gefen delivers innovative, progressive computer and electronics add-on solutions  
that harness integration, extension, distribution and conversion technologies.  
Gefen’s reliable, plug-and-play products supplement cross-platform computer  
systems, professional audio/video environments and HDTV systems of all sizes  
with hard-working solutions that are easy to implement and simple to operate.  
The Gefen CAT5•4000 Extender  
The Gefen CAT5•4000 Extender is an exceptional solution for extending up to  
three individual analog or digital sources to up to four remote locations. The rst  
input is mirrored to two outputs. RS-232 serial communication (four individual  
inputs) and stereo analog audio (available for the mirrored outputs) are also  
provided for extension.  
How It Works  
The CAT5•4000 Extender employs DVI-I inputs which will support both an  
analog and digital signals. This will allow the user to connect VGA and DVI  
sources. Connect the source devices to the CAT5•4000 sender unit using DVI-A  
cables (analog) and DVI-D cables (digital). Connect up to four RS-232 sources  
and a single audio analog stereo to the CAT5•4000 sender unit. Then, using  
inexpensive and widely available CAT-5, CAT-5e or CAT-6 cables, connect up  
to four CAT5•4000 receiver units to the CAT5•4000 sender unit at the remote  
locations. Connect a display to the CAT5•4000 receiver at each location. If using  
the RS-232 or analog stereo extension, connect the corresponding equipment  
to each CAT5•4000 receiver. Once all devices are connected and are receiving  
power a perfectly reproduced video signal should appear on the displays at the  
remote locations.

OPERATION NOTES  
READ THESE NOTES BEFORE INSTALLING OR  
OPERATING THE CAT5•4000 EXTENDER  
Maximum distance ratings:  
VGA 1920x1200 60Hz is 330 feet.  
DVI 1920x1200 60Hz is 130 feet.  
DVI 1280x1024 60Hz is 300 feet.  
VGA Supported resolutions: 640 x 480 through 1920 x 1200  
DVI Supported resolutions: 640 x 480 through 1920 x 1080  
The CAT5•4000 Extender can send only one video type, either analog or  
digital, from each input. While the DVI-I input can accept both types, please  
ensure that only one type of signal is being used by using either a DVI-A or  
DVI-D cable.  
The channel 1 video input will be mirrored to two separate outputs on the  
CAT5•4000 sender unit. However, two separate RS-232 inputs are provided  
and will accommodate an individual RS-232 device for each of the two  
mirrored video outputs.  
Analog stereo audio connected via the 3.5mm mini-stereo input jack will be  
transmitted through the mirrored outputs on channel 1 only.  
Channels two and three do not support audio extension.  
Channels two and three have individual RS-232 connections for use.  
When analog video is used on channels two and three, only a single CAT-5,  
CAT-5e or CAT-6 will be required for full video and RS-232 extension. When  
digital video is being used, two CAT-5, CAT-5e or CAT-6 cables will be  
required for full video and RS-232 support.  
When analog or digital video is used on channel one (this applies to either  
of the mirrored outputs), two CAT-5, CAT-5e or CAT-6 cables will be required  
for full video, audio, and RS-232 support.  
The CAT54000 receiver units need to be congured for use on either  
channel 1 (dual outputs) or for use on channels 2 and 3. There is a  
DIP (Dual In-line Package) switch bank located on the underside of the  
CAT5•4000 receiver that will set the unit for proper operation for either  
channel 1 (both outputs) or for channels 2 or 3. Please see page 14 for  
details on how to change these DIP switches.
