Installation Instructions v1.0

Warning: To be installed and/or used in accordance with appropriate electrical

codes and regulations. If you are unsure about any part of these instructions,
consult a qualified electrician.

Caution: Do not install this product in an electrical junction box with 110V or
higher unless an approved barrier separates the high and low voltage sections.

Introduction: Thank you for purchasing a Knoll active balun system. This system
is specifically designed to send 1080p HDMI and infrared signals safely down
two cat 5e or cat 6 wires up to 100 feet (30 meters) without encountering signal
degradation problems (resolutions lower than 1080p will transmit to further
distances).

To install wires inside walls, in most jurisdictions require wires to be minimum
class 2 rated for safety. Almost all conventional HDMI wires are unrated so they
cannot legally be installed inside walls. The most cost effective method to install
a legal HDMI inwall run is to use cat 5e wire and Knoll HDMI baluns.

Features:

 White color Decora™ style HDMI transmit and receive modules.

 Will safely send 480i/p, 576i/p, 720p and 1080i/p.

 Equalization, level correction as well as clock and data recovery

retiming are fully automatic.

 Infrared receiver and emitter included.

 5 VDC power supply is included

Wiring: A Knoll send
module needs to be
connected to a Knoll
receive module to work
correctly. The send and
receive module are
connected using two
cat 5e or cat 6 wires
using all 8 conductors in each. Connection is made with the RJ45 connector
(RJ45 plug not supplied). Always use standard 568-A cat 5 wiring practices
(shown above). Using the correct wire pairs and polarity is VERY important.

Make absolutely sure the VIDEO port on the send unit is connected to the
VIDEO port on the receive unit. Likewise the DDC port on the send unit is
connected to the DDC port on the receive unit. Both wires are needed.

Please note the maximum cat5e or cat6 wire length for reliable
operation of 1080p is 100 feet or 30 meters. Do not attempt
a longer length as it may not be reliable. For lower resolutions
such as 720p or 1080i the maximum length is 125 feet or 35
meters. Cat 5e and cat 6 wires should be as short as possible.

Never run the cat 5e or cat 6 wires near or along side high
voltage wires. If high voltage lines are near by cross the cat 5e
or cat 6 wires to them at 90 degree angles.

Never coil up cat 5e or cat 6 wires. This can increase the
inductance of the wire and may give an unreliable picture.

Connection to HDMI source equipment: Connect the HDMI IN module
connectors with as short as possible HDMI cord to the source equipment. Less

than 2 meters (6’) is best. The maximum length the HDMI cables to the input
and output combined is about 35’ (10 meters).

Make sure a good quality RJ45 8-8 crimper is used to
connect the RJ45 connector to the cat 5 wire. Poor crimping
and mismatched wires are the most frequent cause of
installation problems.

Power requirements: The Knoll UBWX-HDMI balun system uses a 5 VDC power
supply connected to the send or receive unit. If the cat 5 wires are longer than
50’ (15m) we suggest powering the system on the receive side. There is a
parallel blue color power supply connector on the back of the plate so the 5 VDC
power wires can be hidden behind the cover plate.

Connection to the Projector, TV or other components: Connect the shortest
possible HDMI cable from the receive balun to the projector, TV or other
component. The maximum length the HDMI cables to the input and output
combined is about 35’ (10 meters).

Note: The UBWX-HDMI balun system is not compatible with other Knoll balun
systems. This balun system is not 3D ready. If 3D is required please use one of
other dual or single wire balun solutions. May not work with 36 bit deep color
(may need to change source to 1080i).

Connecting Infrared: The infrared receiver packaged with the UBWX-HDMI can
be connected on HDMI OUT module only. The infrared emitter is connected to
the HDMI IN module only. 38 kHz transmission only.
