1.0 General Description
This User’s Manual covers the Mini-Cat ® series of high-resolution
PC or HDTV component video transmission system.
The transmission systems are comprised of one Sender unit and one
or more Receiver units. They enable you to split and extend a PC
VGA video or analog Component HDTV signal to 500 feet and
beyond. The Model UV1-SL is also capable of extending a Composite
Video & Stereo Audio to 2000 feet.
A unique feature of the system is that in most installations only one
power supply is enough to power the sender and the receiver(s).
All sender units can supply power to all the receivers connected to
them via the Cat5 cable. If the cable is longer than 325 feet or 100 m
then the receiver may require a separate supply. Conversely, in the
case of 1-to-1 setups, the Receiver unit can also supply power to the
Sender (only when the Sender is a single channel).
The characteristics of the Sender units are summarized below:

Note: For Cat-5 runs of over 330 feet, the receivers may need their
own additional supplies sold separately (HRT model # 511-GS569).

3.0 Setup and Operation
A. Place the sender near the video source and connect it to your
source using the cable provided.
• For PC’s VGA output use a HD15 male-to-male cable (generally a
short cable may be included with your package)
• For RGB or YPbPr sources, use a HD15 to 3 RCA cable (Hall
Research Model # CHD15-3RCA-length 03 = 3ft, 06 = 6 ft).
B. Use an Unshielded Twisted Pair (UTP) or a Shielded Twisted pair
(STP) cable such as Cat5, 5e, or 6 wired per standard 568B to
connect the sender to the receiver(s). See Section 3.1 for important
cable selection considerations.
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.

2 Orange
3 White w/Green Stripe

6 Green

8 Brown
C. At each remote site connect a receiver (UV1-R and UV1-R-WP) to
the Cat5 cable and plug your display to its HD15 output connector.
D. Plug a power supply to the System based on the type of the sender
used.

In general, you should connect the power supply to the Sender unit.
However, follow these suggestions for best performance.
• If the sender has more than one RJ45 output (UV2-S, UV4-S,
UV8-S), then the power supply must be connected to the
sender.
• If the Sender is a Model UV1-S, UV1-SL, or UV1-S-WP,
where the system is comprised of only one sender and one
receiver, then you can plug the power supply at either the
sender or the receiver.
Wallplate Power Connection.
The wall plate units, UV1-S-
WP and UV1-R-WP have a 2
pin screw terminal for power
connection. The power supply
output cord does not have a
connector at its end; instead, it
is stripped and tinned. The
positive side has a white line
running along the insulation of
the cable and is marked.
The connection is polarized, meaning the you must connect the +
output wire to the + screw terminal and – to –.
You can use 20 gage or heavier wire to extend the DC output cord of
the power supply if you need to locate the power supply farther from
the device. It is recommended to keep the distance of the supply from
the unit to within 30 feet.
Note: Please do not connect the power supply to the AC source until
you have securely connected the output cords to the Wall Plate Mini-
Cat unit.
E. Apply a video source to the system and check for an image at each
receiver, then set the compensation Potentiometer (pot) for best
possible image.

Start with the compensation pot fully CCW (least compensation), then
slowly turn it clockwise and check for the bleeding of left to right
horizontal lines on the screen.
3.1 Important note regarding selecting the UTP Cable
First of all, UTP (unshielded) is preferred over STP (shielded) unless
you are running the cable very close to AC power lines, power
transformers, or ballasts of fluorescent lights, where EMI (electro-
magnetic interference) can get into the video if it is strong enough.
Secondly, for best results especially for distances of over 150 feet, it
is highly recommended to use a Zero-Skew Cat5 cable. (Hall
Research Part Number CUTP-Z-1000). This cable ensures that the
horizontal alignment of the red, green, and blue components of the

video signal is maintained regardless of the length of the Cat5 cable.
In this cable, the number of twists in each of the 4 pairs in the cable
are the same. If you do not use a Zero Skew cable and feel that the
RGB alignment is off by an unacceptable level, then you can use a
Skew Corrector (Hall Research Model SKU-RGB) at the display
device if desired)
• For Cat5 runs of over 330 ft, you may need to connect a
power supply to the sender as well as the receiver. This is
due to the fact that the resistance of the cable causes a
voltage drop from the sender to the receiver and the voltage
level of the power at the receiver may not be sufficient for
proper operation. This extra power supply must be ordered
separately (Model 511-GS569).
• When using one supply for the system, if the power supply
voltage is not enough due to Cat5 cable run, then, the power
LED on some units may start blinking. This signifies that you
need to attach another power supply to the unit that is
currently being port powered
3.2 Dip Switch Settings for the Model UV1-SL
The UV1-SL can be used to transmit Composite Video and Stereo
Audio as well as VGA to the receiver. However since the Video
signals are terminated differently than audio, you need to move the
dip switch to the proper
position.
Use the Mode Dip Switch to
select the video type for
transmission.
The Sync Dip Switch is used
to change the polarity of
sync at the receiver. If your remote display has trouble positioning the
right and left edges of the screen, then try putting the switch is +/+
