Complete Cat 5 Crimping instructions

The NuVo audio systems require Cat 5, 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 concerto System can accommodate 2000 total feet of
Cat 5 cable. For the most reliable operation, it is best that
no single run of Cat 5 exceeds 250 feet.
The correct wiring scheme for the Cat 5 cable is standard
EIA/TIA 568A. Properly terminating the Cat 5 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 Cat 5 wire tester will insure
that your system operates flawlessly.

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 Cat 5
insulation. It is necessary that the color scheme be
repeated identically on each end of the wire.
