1. Introduction

1.1 General

This User's Manual covers several models of Mini-Cat® Senders. The senders can be any of the following models: UV1-S-16X or UVA-16X. For these units, the number after the dash represents the quantity of RJ45 outputs.

The transmission system is comprised of one Rack-Mount Sender unit and one or more Receiver units (Sold Separately). There are 2 variations of the basic sender which can transmit Video along with either Phantom Power (UV1-S-16X) or Video along with Line-Level Audio (UVA-16X).

The senders convert the video inputs and either power or 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.

At the receiving (remote) end, a compatible receiver (sold separately) is used to convert the UTP signal back to VGA and either power, audio or RS232.

The product is housed in a 2 RU, 19" Rack mount enclosure and has connectors for up to 16 video inputs and Audio depending on the model, as well as multiple RJ45 output connectors for connection to the remote systems.

The RJ45 outputs on the Sender can drive CAT5 LAN cables to 1000 feet (305 meters) with little to no degradation of video quality (500 feet on some models) depending on resolution of the VGA signal (see table 3.2). The receiver can compensate for video signal losses in long cable runs.

1. Connect the included power cord to the power input connector on the unit.
2. Using Category-5 or higher UTP cable, connect one or more compatible receivers to the sender's RJ45 outputs.
3. Connect the remote display/projector and possibly the speakers to the receiver unit.

If using the Model UV1-S-16X, the receivers can be powered from the CAT5 cabling if desired and the cables are less than 500 feet from the sending unit.

CAUTION

Before plugging in the remote monitor, 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 splitter can tolerate up to 5 v peak-to-peak ground potential between the two locations. Failure to ensure good grounding can result in erratic operation and possible shock hazards or damage to your equipment.

NOTICE

Do not connect this unit to any LAN device such as network cards or hubs as this may damage the UVA/URA and/or the LAN device. Use EIA/TIA 568B standard straight-through patch wiring as shown below. Do not use crossover cables.

3. Configuration & Operation

3.1 Sender

At the sending end the video signal from the source is fully terminated. On the UVA-16X, the transmitted audio in the CAT5 cable to the remote receiver is monaural. The audio output on the receiver is “line-level” (powered speakers are required).

3.2 Receivers

Several receiver types are available that are compatible with this family of products (See table for compatible receivers). All Receivers have a single COMPENSATION potentiometer (pot) adjustment to recover high frequency signal loss for long runs of the cable.

Model # Compatible Receivers
UV1-S-16X *	UV1-RUV1-R-WP (Wall Plate)UVB1-CP-R
UVA-16X	UV232A-R*, URA, URA-SKU, URA-XT* - No RS232

\* IMPORTANT

The UV1-S-16X sends 9 vDC via the CAT5 cable and is only compatible with the UV1-R, UV1-R-WP and UVB1-CP-R.

Other types of receivers (Such as a URA) can sustain damage if connected to the UV1-S-16X

Compact CAT5 Audio/Video Splitters and Receiver

3.2.1 Adjusting the video quality for long cable runs

The video quality at the remote station depends on: (1) the length of the CAT5 cable, (2) video resolution setting, (3) refresh rate setting and the model of the receiver.

In general, at low and mid resolutions, excellent image reproduction is provided at up to 1000 feet for UVA-16X model (500 feet for model UV1-S-16X). At high resolution and refresh rates perfect image reproduction can be achieved at shorter distances (see table below). Using longer cables or higher resolution rates will still produce an image, but the reproduction quality will be reduced.

		Refresh Rate
		60 Hz 75	Hz 85 Hz
Resolution	800x600 1000 ft 1000 ft 1000 ft
	1024x768 1000 ft 800 ft 750 ft
	1280x1024 750 ft 650 ft 600 ft
	1600x1200 750 ft 600 ft 500 ft
	20x1440 750 ft 750 ft 500 ft

    B --> C["BLUE"]

UTP cables have 4 twisted pairs inside. The video transmission over UTP uses 3 individual pairs for each color (Red, Green, & Blue). As shown in figure 3.1 above, a characteristic of Category-5/5e/6 cable is that the pairs of wires are twisted at different rates. Therefore, for a given length of Cat-5 cable the total length of a particular pair could be longer than others. Since the signals travel in the cable at a fixed speed, the arrival times of signals can be skewed in a long cable (those that have to travel farther arrive later and the corresponding color shifts to the right).

This is seen on the monitor as separation, or lack of convergence in colors. For example a vertical white line on the screen may look to have a red tinge on the left edge and blue tinge on the right edge.

This effect gets worse at high resolutions, high refresh rates, long cables (in excess of 200 feet), and depends on the cable construction itself. Hall Research highly recommends the use of UTP cables specifically constructed for video transmission. In these cables the all the twisted pairs are the same length. They are available from several sources including Hall Research (part numbers shown below).

If you are going to use commercial grade UTP cable, then we recommend using Cat5 or Cat5e rather than Cat6, since the twist ratio match is better in Cat5 cable.

4. Troubleshooting

4.1 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), make sure that you have adjusted the receiver unit's compensation pot correctly. Also check to see that you have not exceeded the maximum recommended cable length. If you still have a fuzzy image, try reducing the refresh rate and/or resolution of the PC.

If you determine that you have excessive color skew, then you must either consider using Zero-Skew UTP cable, or if that is not possible, use a secondary device whose job is to correct the color skew (please contact Hall Research for details).

Your sender has multiple RJ45 output connectors. When a long CAT5 cable is plugged in any of the outputs, the unit expects a receiver unit at the far end for proper termination. Therefore unplug the un-terminated CAT5 cables from the splitter unit.

2. Image exhibits steady or rolling horizontal color "hum" bars

This is usually an indication of improper grounding either 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 sender can handle up to 5 v pp ground noise between the two locations, but no more.

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 splitter and the interfering source, or use shielded twisted pair (STP) CAT5 cables.

4. The PC does not properly recognize a Plug-and-Play monitor or displays black bars or the desired resolution is not a choice.

Each video input to the system has an EDID available for the video source to read and process. This default EDID should work in most cases without issues and adjustments can be made on the display device. If necessary though, the EDID can be modified by the customer for any of the video inputs by using a Hall Research EDID programmer (purchased separately).

5. Poor audio quality at the receiving end

Only use powered speakers with the splitter and receivers. It is also good practice to set the audio level (volume) output of the PC about 1/2 to 2/3 from the maximum and use the volume knob of the speakers to adjust the volume to the desired level. A low volume signal output from the PC reduces the signal-to-noise (S/N) ratio, whereas too high output amplitude can cause saturation and clipping to occur.

4.2 Calling Hall Research

If you determine that your splitter is malfunctioning, do not attempt to repair the unit. Contact the Hall Research Technical Support Team at 714-641-6607.
