INFORMATION

Model UH-2C

1. Introduction

1.1 General

Hall Research’s Model UH-2C is the latest member of our popular and powerful Mini-CAT® video

extension and distribution product line. The UH-2C is used to extend HDMI™ audio/video signal to

200 ft @ 1080i/720P or 150ft @ 1080p on 2 Cat6 cables. Cat5e cables can also be used, however

when Cat5e is used the maximum distances are reduced by about 33%. Cables that are of lower

quality and construction will also reduce the maximum distance.

The UH-2C is compatible with HDMI™ versions 1.2a and 1.3. Only one power supply is needed for

each Sender/Receiver pair. The remote receiver re-aligns the pixel clock and generates a clean

pixel clock for the display, thereby taking out any skew that may have been induced in the cable.

The Re-clocking feature of the UH-2C allows the units to be daisy-chained together to extend the

video and audio even farther!

This means that you can achieve extremely long distances (for example, with 2 units you can

extend 1080i/720P to 400 ft and farther by adding more units!).

The unit is housed in a compact sturdy metal enclosure measuring 3.25 x 1.75 x 0.85 inch and

includes a power supply.

2. Installation

Refer to figure 1 above. Place the sender by the video source. Use a quality HDMI™ cable to

connect the source to the sender (the cable is not included and must be purchased separately).

Use (2) Cat6 cables to connect the sender to the receiver. Make sure to not cross the connections

as this may cause damage to the unit or the power supply. The RJ45 outputs are labeled as 1 and

2, please label the ends of your UTP cable so that it is easy to plug the ends correctly.

Turn on the display and the video source and plug in the power supply (included) into the receiver.

† For HDMI™ compliance, if the input has HDCP content protection, the display must also be

HDCP compliant (such as a display with HDMI™ input) otherwise no image will be shown on the

display.

Model UH-2C

Note about Twisted-Pair Cables

The UH-2C is designed for operation with standard Cat6 cables (TIA/EIA 568B wiring). You

can use Cat5e cables also if the distance between sender and receiver is 70 ft or less.

Shielded Cat6 can also be used; in fact, shielded Cat6 offers the best performance and

provides immunity to external noise if the installation is in an electrically noisy environment.

Avoid using Zero-skew or low skew cables. The low skew cables work well for analog video

extension over twisted pair, but since the UH-2C is a pure digital system, the cross-talk of

the low skew cables will actually shorten the maximum achievable cable length.

3. Troubleshooting

There are no field serviceable parts or circuits in the device. If you think that the device is

malfunctioning, please first try the following steps:

Check to make sure you haven’t crossed the 2 Cat6 cables

Check the video connections

Unplug the power supply and re-attach it

Connect the display directly to the source and make sure you can get a picture without the

extender. If so then using the menus of the video source try to set the output resolution to

a low one (such as 480p) to start with. Insert the extender and verify that you get an

image, if so; then set the resolution to the next higher value (such as 720p). Continue this

process until you get the highest possible resolution without loss of image or audio.

The quality of the cable and the connections will determine the maximum length and

resolution achievable. Certain types of cable may be able to show the video, but the audio

will not be heard.

3.1 Contacting Hall Research

If you determine that your extender is malfunctioning, do not attempt to repair the unit. The unit

contains no user serviceable equipment. Opening the unit will void the warranty. Contact the Hall

Research Technical Support department at 714-641-6607 to obtain a RMA (Return Authorization)

number.

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.

3.2 Shipping and Packaging

If you need to transport or ship your extender:

• 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.
