Installation Instructions v1.4

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

appropriate electrical codes and regulations. If you are not sure
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 your purchase of a Knoll active
balun system. This system is designed to send a three wire Pb,
Pr, Y component or RGB, digital audio (Dolby® digital or
DTS®), analog stereo audio and infrared signals safely down
two CAT5 or CAT5e wires up to 500 feet without encountering
signal degradation problems. Balun is an acronym for:

BALance – UNbalance

The send module takes a conventional component signal, analog
and digital audio and balances it (signal is not tied to a ground
reference) then sends it via two cat 5 wires to the receive
module (with power from the send module). The receive module
unbalances the signals back to their former state. This process
does not allow any stray magnetism of any sort to contaminate
the signal while it is being transported.

Features:

• Send component video signals.

• Will safely send 480i/p, 720p and 1080i/p signals.

• Send analog audio and digital audio.

• Send infrared signals

• Two CAT5 or CAT5e wires required.

Wiring: A send
module (UDS-Multi)
needs to be
connected to a Knoll
receive module
(UDR-Multi) to work
correctly. The send
and receive modules
are connected using
two CAT5 wires using all 8 conductors on both wires. Connection is
made with the RJ45 connector (RJ45 plug not supplied). Always use
standard CAT5 wiring practices. Using the correct wire pairs and
polarity is VERY important.

Connection to stereo video source equipment: Connect the one or
three UDS-Multi gold video RCA jacks with a good quality gold
connector RCA jumper cable to the appropriate three component
output jacks on your DVD, dish receiver, D-VHS, VCR, stereo or other
equipment.

Connect the analog stereo or digital audio output to the UDS-Multi.

If there is a switched outlet on your output equipment, you may want
to plug the PS1205 power supply to the switched outlet.

Make sure a good quality RJ45 8-8 crimper is used to
connect the RJ45 connector to the CAT5 wire. Poor crimping
and mismatched wires are the most frequent cause of
installation problems.

Power requirements: The Knoll multi balun system requires one
PS1205 power supply connected to either the send or receive unit but
not both.

Connection to the Projector, TV or other components: Connect
the one or three video gold RCA jacks with a good quality gold
connector RCA jumper cable to the appropriate three component
input jacks on your projector, plasma, TV or other component. Make
sure the correct projector, plasma, TV or other component input is
selected.
Connect the analog stereo or digital audio input to the UDR-Multi.

Infrared: The Knoll stereo balun system can carry infrared signals in
either direction. An infrared receiver (not supplied) is connected using
its signal and ground outputs connected to the mono jack on either the
send or receive balun (tip is signal or IR output and sleeve is ground on
the 3.5mm jack). A separate power supply for the infrared receiver is
required.

An IR54 or IR55 connection module is connected using the ground and
IR signal terminals on the IR54 or IR55 and a mono 3.5mm jack
connected to the other balun. Again the 3.5mm jack tip is the IR output
and the sleeve is ground. Plug emitters to the IR54 or IR55.

If an emitter is directly connected to the send unit without a
connection block, a 470 ohm dropping resistor needs to be inserted

in series in the emitter wire or the emitter will fail after a short period
of time.
