1. Introduction
1.1 Model UV-1 … for VGA
The Model UV1 is a single channel UTP (CAT5) VGA video extender
consisting of a sender (UV1-S) and a receiver (UV1-R) sold together as
a pair. The sender converts a PC's VGA signal into a format that can be
transmitted using a single inexpensive and commonly available
Category-5 Unshielded Twisted Pair (UTP) cable with RJ45
connectors, which is used in most Local Area Networks.
At the receiving (remote) end the Cat5 signal is converted back to VGA
for connection to your monitor, projector or other display device.
The sender and receiver are each housed in a small plastic enclosure
and include a HD15 video connector and a RJ45 connector for the Cat-
5 cable. Included with the pair of devices are: one small power adapter
(can be powered at either end), and a short adapter cable for easy
connection to the standard HD-15 connector of the PC.
The Mini-Cat® brand extenders can drive CAT5 LAN cables to 500
feet (150 meters) with little to no degradation of video quality.
1.2 Model UV-1-CP … for Component Video (RGB or Y Pb Pr)
This variation of the UV-1 includes cables for each end that allow you
connect the sender to the 3 RCA connectors of DVD-players or other
video sources that output Component Video (RGB or Y Pb Pr, or Y Cb
Cr) and the receiver to connect to compatible displays such as HDTV’s
or high-end monitors. The actual sender and receiver units are identical
to the standard UV-1 and, in fact, you can use the pair to send VGA
video if you substitute VGA cables.
1.3 Model UV-1-CV … for Composite Video and Stereo Audio
This variation of the UV-1 includes cables for each end that allow you
to connect the sender to the composite Video (Yellow), Left Audio
(White) and Right Audio (Red) connectors of your A/V equipment. It
can actually send the signals in excess of 1200 feet (365 meters),
though both ends need to be powered if the distance is beyond 500 ft.
Unlike the UV-CP, the UV-1-CV is not compatible with VGA signals.

1.4 Features
•Eliminates the need for bulky, expensive and hard to build
multi-coaxial cables for High-Resolution A/V extension
•Amplifies the signal for clean and crisp transmission
•Differential signaling eliminates ground loops and noise
•Handles resolutions up to 1600x1200 at any refresh rate
•Rugged, Reliable, Compact size
•Only one end requires power in most applications. Power
supply can be connected at the sending or the receiving end,
whichever convenient.
•Drive standard CAT5 cables to 500 feet for (VGA and
Component video versions) or to 1200 feet for (Composite
Video and Stereo Audio version)
2. Installation
1. Connect the VGA in (HD-15) connector of the UV1-Sender to the
computer's video port using the supplied cable (see figure 2.1).
2. Connect the supplied power adapter to the power input connector
on either of the units. Note that only one power adapter is used to
power both the sender and receiver. It can be plugged into either of
them. Please be sure to insert the power connector fully. You may
need to push down on the connector as shown below. Check the red
light next to the RJ45 connector to verify unit’s power.

Recommended Power Supply Connection
qCat 5 cable length of 0 to 150 feet:
It does not matter in which end you plug the power supply. Do
whatever is most convenient for your setup.
qCat 5 cable length of 150 to 300 feet:
We recommend that you plug the power supply at the receiving
end.
qCat 5 cable length of 300 to 500 feet:
Still you should plug the power supply at the receiving end,
however, depending the grounding of the video source (PC) and
the display device at the remote end, you may need to purchase an
additional power supply to power up both ends.
qCat 5 cable lengths over 500 feet:
Purchase of an additional power supply to power up both ends is
almost certainly needed.
3. Using Category-5 cable connect the UV1-Receiver to the unit's
RJ45 output. Connect the remote monitor to the receiver.
IMPORTANT
Do not connect this unit to any LAN device such as network cards or hubs
as this may cause damage. Use EIA/TIA 568B standard straight-through
patch wiring as shown below. Do not use crossover cables.

3. Configuration & Operation
The Mini-Cat® Receivers are equipped with an adjustment to improve
image quality when using long cables. The adjustment is made via a
single turn trim-pot located next to the power connector on the receiver.
When using a long cable, with no
compensation, any solid horizontal line,
tends to smear to the right. For example
in the image shown, observe the dark
black line at the bottom of the window
and see how it is smearing to the right
(not changing to white abruptly as it
should). This is the effect of long cable
on the signal.
You can turn the trim-pot to eliminate
these streaks as shown on the 2nd
picture. If you add too much
compensation to the signal, then an
opposite effect may be observed, i.e.
black lines smear to the right as white
lines or vice-versa. The 3rd picture
shows the case where too much
compensation is added.
In general, when using long cables, the
image quality is a function of resolution
and refresh rate. If possible, set the
refresh rate to 60 Hz at any resolution.
Also for best results at long distances,
try to use standard Category-5 Cable (instead of
CAT5e or CAT6 since CAT5e and CAT6 cables may have widely
dissimilar twist ratios of the wire pairs in the cable that may result in
noticeable color skew).

4. Troubleshooting
1. Fuzzy, blurry, or ghosting image at remote location
If you have a stable image but it looks somewhat blurry (object or
character edges are not sharp), try to adjust the compensation first.
When the trim-pot is turned fully CCW there is no compensation. As
you turn the pot clockwise you are applying compensation. Look at the
screen and slowly turn the pot clockwise. Notice what happens to the
right of solid horizontal lines (as in figure 3.1). If you still have a fuzzy
image, try reducing first the refresh rate and then the resolution of the
PC.
2. Shaking image or periodically blanking monitor
Although CAT5 cable uses twisted pairs to transmit the signals from the
splitter to the receivers to reduce the amount of EMI coupled noise
from external sources, a strong electromagnetic noise field can cause
instability in the signal. Usual sources of this form of noise coupling are
high current AC lines or other high-density data and/or control cables
that run adjacent to and parallel with a substantial length of the CAT5
cable.
To eliminate this, either separate the Cat 5 cable of Mini-Cat® from the
interfering source or use shielded CAT5 cables. Note that separating the
CAT5 cable from the EMI source by a few inches is often sufficient to
eliminate this problem.
3. The PC does not recognize a Plug-and-Play monitor
If the PC’s Operating System is setup to detect a plug-and-play monitor
(usually in Display Properties Advanced Settings), it may have trouble
finding a monitor. If the PC does not produce an image due to this,
disable the plug-and-play monitor detection in the PC’s operating
system Display properties.
4. Substituting power supplies
The sender and receiver rely on the power adapter that is supplied with
them. Do not substitute any other power supply or DC power source
