Compact CAT5 Audio/Video Splitter and Receive

1. Introduction

1.1 General

This User’s Manual covers both the splitters (senders) and the Remote

Receivers. The splitters can be any of the following models: UVA-2, UVA-4,

UVA-8, or UVA-24. For these units, the number after the dash represents the

quantity of RJ45 outputs.

The basic receiver unit which works with any of the splitters is Model URA.

There also some variations of the basic receiver such as one that has 2 sets of

Video and audio outputs (Model URA-X2), or one with powered audio output and

volume control (URA-VOL).

The splitters (senders) convert a PCs VGA and audio signals into a format that

can be transmitted using a single inexpensive and commonly available

Unshielded Twisted Pair (UTP) cable with RJ45 connectors. Both UTP and STP

(shielded) cables can be used. In addition you can use Cat5, 5e, 6, or higher.

However, for runs of over 250 feet, Hall Research recommends using “Skew-

free” or “Zero-skew” Cat5 cables for best performance. The senders also have

local buffered loop-thru outputs for the VGA and audio for connection to local

monitor or expansion.

At the receiving (remote) end, a receiver Model URA (sold separately) is used to

convert the UTP signal back to VGA and audio.

These products are housed in compact shielded enclosures and include

connectors for a local monitor and speakers as well as multiple RJ45 connectors

for connection to remote monitors.

Included with the devices are: a small power supply. The senders also come

with short video and audio cables for connection to the PC VGA and sound

card’s outputs.

The RJ45 outputs on the Splitters can drive CAT5 LAN cables to 1000 feet (305

meters) with little to no degradation of video quality depending on resolution of

the VGA signal (see table 3.2). The receiver can compensate for signal losses in

long cable runs.
