1. Introduction
1.1 General
This User Manual applies to model number UV4-S and UV8-S Mini-Cat ® series of
high resolution PC or HDTV component video system.
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).
These devices are four (4) or eight (8) Channel Splitters for PC Video & power over
Twisted-Pair senders
In a typical application, they are located at the video & power source and connected
to one or more compatible receiver units.
Low-skew UTP cable (such as Hall Research’s Zero-skew™ CAT5 cable) is
recommended with the Model UV1-R particularly if cable lengths are 200 feet or
longer.
1.2 Features
•Support for local monitor at transmitter
•Multiple CATx outputs
•Transmits video and phantom power on a single CATx cable
•Compact & rugged metal enclosure
•Eliminates the need for bulky, expensive and hard to build multi-coaxial
cables for high-resolution video extension
•Amplifies the signal for clean and crisp transmission
•Differential signaling eliminates ground loops and noise
•Handles resolutions up to 1920x1440 at 60Hz
•Rugged, Reliable, Compact size
•Drive standard Cat5 cables to 500 feet for (VGA and Component Video)

2. Installation
2.1 Package Contents
Your package should contain the following items:
(1) UV4-S or UV8-S
(1) Universal power supply (9 VDC) with IEC320 Power Cord
(1) 6 ft HD15-M-M VGA cable
(1) User manual
(1) Screwdriver
2.2 Connection to Compatible Receivers
The UV4-S and UV8-S units have a single UTP cable connection to Hall Research’s
UV1-R receiver product line.
Connect the UTP cable from the UV1-R receiver to the “UTP OUT”
connectors of the UV4-S or UV8-S.
Connect the HD15 - “PC/HD IN” connector to the video source. For YPbPr
video sources, use a 3-RCA to HD15 cable (Hall Research P/N CHD15-
RGB).
Connect the HD15-“PC/HD OUT” connector to a compatible video display.
Connect the included power supply to the center positive +9 VDC power
input connector on the UV4-S or UV8-S.
oIf the UTP cable to the UV1-R receiver is
longer than 330 ft (100m) then a power
supply may be needed at the receiver
(sold separately HR Model # 511-GS569).
Never use any other power supply as this may
damage the device.

2.2 Cable Requirements
All units can use with CAT5/5e/6 or Zero-Skew™ UTP or STP (unshielded or
shielded twisted pair) cables. Low-skew UTP cable (such as Hall Research’s Zero-
skew™ CAT5 cable) is recommended particularly if cable lengths are 200 feet or
longer.
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.

3.1 Receiver Video Adjustment (High Frequency Compensation)
Apply a video source to the system and check the image at each receiver’s display.
Set the compensation potentiometer (pot) on the Model UV1-R receiver for best
possible image.
Start with the compensation pot fully CCW (least compensation), slowly turn it
clockwise and check for bleeding of left to right horizontal lines on the screen. See
Figure 3 below.

4. Troubleshooting
There are no field serviceable parts or circuits in the device.
Opening the unit will void the warranty.
If you think the device is malfunctioning (or you have no picture output), please try to
use the methods described in Section 4.3 below to obtain a picture first.

4.1 Contacting Hall Research
If you determine that the UV4-S or UV8-S is malfunctioning, do not attempt to repair
the unit instead, contact Hall Research Technical Support at 714-641-6607.
Before you do, make a record of the history of the problem. We will be able to
provide more efficient and accurate assistance if you have a complete
description.
4.2 Shipping and Packaging
If you need to transport or ship your unit:
•Package it carefully. We recommend that you use the original container.
•Before you ship the units back to Hall Research for repair or return,
contact us to get a Return Authorization (RMA) number.
4.3 Problem Solving FAQ
1. Fuzzy, blurry, or ghosting image at remote location
If you have a stable image but it looks somewhat blurry (edges are not
sharp), ensure the cable length for the resolution and refresh rate used is
within the recommended limits. If you still have a fuzzy image, try reducing
the refresh rate and/or resolution of the video source.
2. Image exhibits steady or rolling horizontal color “hum” bars
This is usually an indication of improper grounding at the sending end, the
receiving end, or both. Verify that the AC line is properly wired and that a
protective ground (green) wire is established with NO potential difference
between both the sender and receiver locations. The UTP splitter can
handle up to 5 volts peak-to-peak of ground noise between the two
locations, but ground potential differences more than this can show up on
video.
3. Shaking image or periodically blanking monitor
Inherently, balanced signal transmission over twisted pair offers good
immunity to EMI coupled noise from other external sources. However, a
strong electromagnetic noise field can cause instability in the signal.
Usual sources are high power AC lines or data and/or control cables that
run adjacent to and parallel with a substantial length of the CAT5 cable. To
eliminate this, either place a distance between the CAT5 cables from the
sender and the interfering source, or use shielded twisted pair (STP) CAT5
cables.
