RADIO FREQUENCY INTERFERENCE STATEMENT
This equipment generates, uses, and can radiate radio frequency energy and if not installed
and used properly, that is, in strict accordance with the manufacturer’s instructions, may
cause interference to radio communication. It has been designed to comply with the limits
for a Class A computing device in accordance with the specifications in Subpart B of Part 15
of FCC rules, which are intended to provide reasonable protection against such interference
when the equipment is operated in a commercial environment. Operation of this equipment
in a residential area is likely to cause interference, in which case the user at their own

1. Introduction
General
Hall Research’s Model UH-2D-3S is a member of the Mini-CAT® video extension product
line. The UH-2D-3S is used to extend HDMI™ audio/video signals on Cat6 cables to 3
remote receivers (Model UH-2D-R). The device provides one local HDMI output and 3 sets
of RJ45 pairs for connection to the remote receivers.
The UH-2D-3S is compatible with HDMI™ versions 1.2a, 1.3 and 1.4 in terms of 3D, deep-
color, and 4K video support. The remote receiver (UH-2D-R) includes state of the art
automatic equalization to compensate for signal losses in the cables and produces a crisp
image as clear as the original.
The unit is housed in a compact sturdy metal enclosure that is 1RU high. Two can be
mounted side-by-side using Hall Research Model RMS-1U-1A rack shelf (UH-2D-3S has
threaded holes on the bottom for this purpose), or a single unit can be mounted using the
Model RMK-05 Rack Mount Kit

4. Controls, Functions and Indicators
UTP PORT Status Indicators
Each of the 3 UTP outputs has two LED indicators
REMOTE PWR: Indicates that the UH-2D-R remote receiver is powered up
LCD DETECT: Indicates that HPD (Hot-Plug Detect) signal is active
Power Indicator
The power indicator is illuminated when power is applied to the unit.
100/240 VAC Power Input Jack
Connect this jack to AC using standard power cables

HDMI Input Connector
Connect the HDMI SOURCE to this connector using the provided cable.
UTP Output #1 thru #3
These outputs are labeled as A and B (on some units A is labeled as CAT6-1 and B as
CAT6-2). The UH-2D-R remote receivers have corresponding RJ45’s. Connect A to A and
connect B to B
HDMI Output (loop out)
Connect a compatible HDMI Display device to this connector. Note the order of HDMI output
connections determines the EDID presented to the HDMI SOURCE described below.
Service Connector
No user functionality- for factory use only.
EDID Selection Switch
Default position is NORM. In this mode the unit will scan the outputs and create an EDID
based on connected LCD’s. In EMUL mode the unit will use a generic EDID that is
independent of connected LCD’s. Read more about EDID in the next section.
5. EDID Handling
NORM (pass-thru EDID)
After power-up, the unit scans the outputs and looks for connected display devices (SINK).
The local HDMI output has priority and if the unit detects a connected sink its EDID is read
and recorded in internal memory and is passed on to the input source. If no display is
connected to this output then the unit will look for a display on the UTP outputs and the first
one discovered will have its EDID read.
If no display is found on any of the outputs, an internal pre-programmed EDID is used and
passed on to the input source.
EMUL (Emulated EDID)
After power-up, the unit uses an internal pre-programmed generic EDID and passes it on to
the source. Please contact Hall Research Support for further details or questions.
6. Installation
Refer to the block diagram and the rear panel connections above. Place the sender by the
video source. Use the supplied HDMI™ cable to connect the source to the sender. 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 A and B, so
please label the ends of your UTP cables so that the end can be identified correctly.
The UH-2D-R remote receivers require power supplies attached to them (they come with
a 5v power supply). So make sure to plug in the power supply to each receiver.

Note about Twisted-Pair Cables
For best results we recommend using Shielded 23 gague Cat6 cables (STP). Unshielded
23 gague Cat 6 Cables also provide acceptable results and can be used in 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 but since the
UH-2D is a pure digital system, the cross-talk of the low skew cables will actually shorten
the maximum achievable cable length
With 23 Gague Cat6 cables the maximum length of cable depends on the resolution as
shown below:
Resolution
Max Cable length
480i, 480p, 576i, 576p, 720p, 1080i
170 ft (52 m)
1080p @ 60 Hz 8 bit per color (24 bit)
130 ft (40 m)
1080p deep-color 12 bit per color (36 bit) 80 ft (25 m)
4Kx2K
40 ft (12 m)
7. Troubleshooting
There are no field serviceable parts or circuits in the device. If you think that the device is
malfunctioning, please try the following steps first:
Make sure the 2 Cat6 cables are not crossed and RJ45 ends are fully inserted.
Check the video connections. HDMI cables can come loose and cause video loss
Unplug the power supply and re-attach it to cycle power
Check the indicator lights on the front panel and on the top of the Receivers for clues
Try placing the EDID routing switch in EMULATE mode (particularly if you don’t have a
local LCD hooked up).
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 UTP cables is very important 23 gage Cat6 is recommended
