1. Introduction
1.1 General
Hall Research’s Model UH-2C-3S is a member of the Mini-CAT® video extension and distribution
product line. The UH-2C-3S is used to extend HDMI™ audio/video signal up to 150ft @ 1080i/720p
on 2 Cat6 cables to 3 remote receivers (Model UH-2C-R). The unit provides one local HDMI output
and 3 sets of RJ45 pairs for connection to the remote receivers. Cables that are of lower quality
and construction will reduce the maximum distance.
The UH-2C-3S is compatible with HDMI™ versions 1.2a and 1.3 and also supports 3D video. The
remote receiver (UH-2C-R) 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. This allows daisy-
chaining (to achieve further extension), and produces a crisp image as clear as the original.
The unit is housed in a compact sturdy metal enclosure that is 1RU high so that several can fit on a
Rack Shelf (Model RMS-1U-1A).

2. Installation
Refer to the block diagram (figure 1) and the rear panel connections (figure 2) 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. Do 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, so 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.
3. Front Panel Indicators
In addition to the power indicator LED, this unit is equipped with (6) LED’s that show the status of
the remote receivers on UTP ports. These indicators are a great tool for helping ascertain possible
reasons if a remote display is not working.
Figure 3 – Front Panel Indicators
Each port (1, 2 and 3) features two vertically-arranged status indicators. If the top LED (REMOTE
PWR) is lit, then the corresponding remote receiver (UH-2C-R) is successfully powered up and
connected to the sender. If the bottom LED (LCD DETECT) is lit, then the connection of the
receiver to the LCD is verified (via Hot Plug Detect of the HDMI cable to the LCD). Therefore if
both LEDs are lit, you should have an image on the remote LCD - of course the LCD should be
powered up and the length and quality of UTP cables must be within the specified limits.

Note about Twisted-Pair Cables
For best results we recommend using Shielded 23 Gage Solid Cat6 cables Unshielded
(UTP) 23 AWG Cat 6 Cable also provides great results and can be used if noise free
environments.
Use TIA/EIA 568B straight through wiring termination. 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.
4. 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 the 2 Cat6 cables are not crossed.
Check the video connections.
Unplug the power supply and re-attach it.
Check the indicator lights on the unit. If the top LED (REMOTE PWR) for the desired port
is unlit, please verify that the 5v power supply is connected to the receiver (UH-2C-R) and
that the 2 Cat6 cables are connected between the sender and receiver. If the bottom LED
(LCD DETECT) for the desired port is unlit, please verify that the remote LCD is on and
connected to the receiver (UH-2C-R).
Connect the display directly to the source and make sure that an image is present without
the extender. If so, then use the menus of the video source to lower the output resolution
(such as 480p). 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.
