Installation manual

Several topologies are possible within the DMS includ-
ing:
• An audio/video networking scheme, with A/V or PC
components sending and receiving audio/video sig-
nals via a single send and multiple receive units and
the centralized hub
•A hub-to-receive model where information is sent
from the hub to remote receive units
•A point-to-point model where the send and receive
units are linked directly together
The DMS has the following features:
•"Daisy chain" feature for hubs: distribute audio/video
signals to over 20 locations
• Composite (baseband) RCA inputs (L/R Audio and
Video) for connectivity directly from a single audio/
video source
• Send and receive units fit standard single-gang elec-
trical boxes and LV rings
• Advanced circuitry with automatic equalization
streams analog audio and video signals with less dis-
tortion
• Stereo audio input/output handles Dolby®
ProLogic™ surround signals
All the components in the DMS are run on DC and can
be powered either independently or through the Media
Hub. Important: This product requires a dedicated
Category 5 or 5e run.
Note: The DMS Hub requires the 15 VDC Transformer

9.7.1 Stereo Modulator
The Stereo Modulator (P/N 48210-DSM) is a desktop-
style device designed to work with audio/video compo-
nents such as DVD players. It takes the signal from an
audio/video component and converts the signal to a
cable TV channel that can be broadcast over the whole-
house coaxial network to multiple televisions on one un-
used cable channel, effectively setting-up an in-home
entertainment channel. The “frequency agile” modulator
outputs on any UHF channel between 14 and 69 or
CATV channel between 54 and 94 and 100-125 (chan-
nels 75-80 are recommended with the Notch Filter, P/N
47689-B).
9.8 Multi-Room Stereo Infra-Red
(IR) Control Connection
Each room wired for sound is a candidate for remote
infra-red or IR control. With an IR control, your client
can select individual CD’s or choose remotely between
sound sources (CD or FM, for example). Connecting a
remote IR control is relatively simple, as it does not en-
tail the same current and impedance considerations as
do multi-room speakers and volume controls.
Think of Multi-room IR as an extended remote control.
The remote control’s IR signals are received by an IR
Room Target (P/N 47621-MIE)
mounted in a centrally-
accessible location within a room. Each Room Target
converts IR commands from a remote control into
electrical impulses. At the other end (the audio/video
components to be controlled), an IR Emitter Bug (P/N
47621-CMS) converts these electrical impulses back
into IR signals that are then received by the A/V gear’s
built-in remote sensor as if the remote control were in
the same room. The 1x9 Bridging Module (connects
multiple emitters to multiple IR targets. Targets are lo-
cated in remote rooms from which the user will want to
control the system. The IR Targets link back to the
Bridging module, from which the command signals
are routed back to the audio/video component emit-
ters also over Category 5 or 5e cable.
9.8.1 Installing Targets and Emitters
IR Targets can be installed in celings or walls where
they will not be blocked by furniture. Connect the tar-
gets to Category 5 or 5e cable (previously installed and
left hanging through a small 1/2" diameter hole in the
drywall). Use the small wire nuts supplied with the tar-
get to connect the red wire to the brown pair, the black
wire to the green pair, and the yellow wire to the orange
pair of the Category 5 or 5e cable. Once all connec-
tions are secure, carefully work the target firmly into the
drywall hole.
At the Audio/Video (Home Entertainment) Center
Audio/video (A/V) components come with built-in re-
mote sensors that work in conjunction with remote con-
trols. To find this sensor:
