PC (VGA) & HD (YPbPr) AV over Twisted-Pair Receivers

1. Introduction
1.1 General
This User’s Manual applies to Hall Research Models URA, URA-
SKU, and URA-XT.
These models are video and audio over Category 5/5e/6 receivers. In
a typical application, they are located at a distance from the video
source and are connected to a compatible sender unit that converts
the audio and video source signal for transmission on twisted pair
cable.
Below is a list of capabilities & features of each receiver model:

Table 1 – Model Number Differences
Low-skew UTP cables (such as Hall Research’s Zero-skew™ Cat5
cables) are recommended with the Model URA particularly if cable
lengths are 200 feet or longer. The Models URA-SKU and URA-XT
do not have any special cable requirements since they are capable of
correcting the RGB color skew that is induced in typical Cat6 cables.
The Model URA-XT allows downstream receiver units to daisy chain
connections using UTP cables. This eliminates the need for running
separate cables from every receiver back to the sender (in star or
home-run fashion) – a very useful feature when several receivers are
located in a line going away from the sender.
Depending on the application, the URA-XT’s downstream RJ45 port
can be connected to another receiver (URA-XT, URA-SKU, or URA).
The constructed daisy chain may have:
•
Up to 3750 feet maximum cable from source to last URA
•
A maximum of 5 URA devices in any chain
•
750 feet maximum distance between units in a chain
