Compact CAT5 Video/RS232 Splitters and Receivers

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: UV232-2,
UV232-4, UV232-8, or UV232-24. 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 the
Model UR232. Another receiver is the Model UR232-X2, which has 2
sets of Video and RS232 outputs.
The splitters (senders) convert a PC's VGA and RS232 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 RS232 for connection to
local monitor or expansion.
At the receiving (remote) end, a receiver Model UR232 (sold
separately) is used to convert the UTP signal back to VGA and RS232.
NOTE
The UV232 supports bidirectional RS232 (Transmit / Receive) at sender
RS232 Loop Out, and unidirectional (Transmit only) to UR232 receivers.
Remote RS232 devices cannot transmit back to PC.
These products are housed in compact shielded enclosures and include
connectors for a local monitor and RS232 device 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 mini-stereo to DB9 cables for connection to
the PC’s VGA and serial port 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.
