OPERATION NOTES
INTRODUCTION
Thank you for purchasing the DVI CAT5 4X Extender.
The DVI CAT5 4X Extender can extend 4 single link (1920 x 1200) DVI sources
to 4 displays up to 300ft away.
The 4x4 DVI CAT5 Distribution Amplier is the perfect solution for anyone who
needs to send multiple sources to multiple displays in remote locations at the
same time.
The DVI CAT5 4X Extender has 4 DVI single link inputs with 8 (2 per display)
RJ45 output ports. Each pair of CAT5e cables will extend out to a single receiver
with 2 RJ45 inputs and one DVI output port for your display. This will allow you
to extend 4 separate video signals to 4 remote locations.

READ THESE NOTES BEFORE INSTALLING
OR OPERATING THE DVI CAT5 4X Extender
• The DVI CAT5 4X Extender and DVI CAT5 MSR units are housed in a metal
box for better RF shielding.
• Your CAT5e cables should not exceed 300 feet.
• If you do not need DDC or HDCP data you can use a single CAT5e cable for
the video only. The DDC will not be connected. (For further information, see
our Terminology section on page 9.) If HDCP is required, both CAT5e cables
must be used between the sender and receiver units.
• If you are using a single CAT5e cable and the source requires EDID present,
you can use the Gefen DVI Detective to provide EDID information to your
source. The DVI Detective will not transmit HDCP.
• Shielded CAT5e or CAT6 with metal RJ-45 connectors is recommended to
protect from random video ashes caused by EMI.
• Power supply for the receiver should not be connected unless you are using
one CAT5e or going over a distance of 180ft.
• Extensions over 130ft. require you to manually EQ your signal (see page 5).
• Extensions under 130ft. use Auto EQ (which is on by default) (see page 5).
NOTE: The DVI CAT5 4X Extender is fully HDCP compliant

HOW TO USE THE EQ TRIM POT
The EQ trim pot is used extensions over 130 ft. By default, the DVI CAT5
MSR receivers come set to "Auto EQ" (with dip switch 1 ON). Underneath
the receiver is a bank of dip switches hidden by a blank sticker. If you ip dip
switch 1 OFF you can turn off the "Auto EQ" so that you can manually EQ your
signal by using the EQ trim pot on the receiver. If you ip dip switch number
1 to the ON position you can set the DVI CAT5 MSR to "Auto EQ". Auto EQ
works only when the sender is set to "NO BOOST" (see page 6). Auto EQ
works reliably up to 130ft. If you are using the DVI CAT5 MSR beyond any
distance of 130 ft. you will have to manually EQ your signal.
USING THE TRIMPOT
Have both of your CAT5e or CAT6 cables connected.
Start by having the source connected and playing with your display on.
Start with the trimpot turned all the way counter clockwise and slowly turn
the trim pot clockwise until the image stablilizes and displays no noise.

If you still do not get a picture or have video noise, set the sender's to medium
boost and try to re-EQ your signal. If that still does not work try the high boost
setting.

DIP SWITCH GUIDE
6
The EXT-DVI-CAT5-4X and EXT-DVI-CAT5MSR products both contain a set
of service switches (also called dip switches) located underneath each unit.
The EXT-DVI-CAT5-4X has 4 sets of DIP switches, one for each input, while
the EXT-DVI-CAT5MSR has a single bank of DIP switches. Peeling back the
silver sticker on the bottom of either unit will reveal the DIP switch bank. These
service switches are used to boost and equalize the signal to best match the
conditions in your setup. (*Note: Adjustments should be done with sources
and display on. Switches 3 and 4 are not used.)

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)
