Installing the Simplese System in Your Home
I. Prewire
The Simplese System uses CAT5 cable for keypad control and either two or four-conductor 16-gauge speaker wire. All the wire is
“homerun” from each zone to the location of the Allport connection hub.
Complete CAT5 Crimping Instructions
The NuVo audio systems require CAT5, unshielded, twisted
pair (UTP), for communication between the
keypads/Display Pads and the main amplifier unit. Each
end of the wire is terminated with an RJ45 connector.
The Simplese System can accommodate 2000 total feet of
CAT5 cable. For the most reliable operation, it is best that
no single run of CAT5 exceeds 250 feet.
The correct wiring scheme for the CAT5 cable is standard
EIA/TIA 568A. Properly terminating the CAT5 cable is
crucial for the operation of the system. It is very important
to use a good quality crimp tool, and testing each end to
end run with a CAT5 wire tester will insure that your
system operates flawlessly, fig.1.
Step-by-Step Crimping Instructions
1.
Strip a 2 to 3 inch portion of the insulation,
exposing the 4 twisted pairs.
2. Untwist the wires and fan them out
individually. Arrange the wires into the
correct color scheme as shown in Fig. 1.
3. Flatten the wires in their correct order, and trim
them evenly across the top. Most crimp tools have
a wire trimmer built-in. It is best to trim the wires
to about ½” in length.
4. While holding the wires flat between your thumb
and forefinger, insert the wires into the RJ45
connector, so each is in its own slot. Push the wire
into the RJ45, so all 8 conductors touch the end of
the connector. The insulation jacket should
extend beyond the crimp point of the RJ45.
5. Insert the RJ45 into the crimp tool receptacle and
squeeze the tool firmly. Note that a ratchet type
tool should tighten down until it no longer clicks.
6. The RJ45 should be firmly crimped to the CAT5
insulation. It is necessary that the color scheme
be repeated identically on each end of the wire.
