I. Complete Crimping Instructions
for Cat-5 (Fig. 1)
The NuVo audio systems require Cat-5, unshielded,
twisted pair (UTP), for communication between the
keypads and the main amplifier unit. Each end of the
wire is terminated with an RJ45 connector.
The correct wiring scheme for the Cat-5 wire is stan-
dard EIA/TIA 568A, which is the industry standard for
computer networking. Properly terminating the Cat-5
wire is crucial for the operation of the system. It is
very important to use a good quality crimp tool, and
testing each termination 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, expos-
ing the 4 twisted pairs.
2. Untwist the wires and fan them out individually.
Arrange the wires into the correct color scheme.
Note that each of the wires is either a solid color, or
a white wire with a colored stripe. The colors are
green, orange, blue, and brown. The colors need to
be in the order 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 1/2" in length.
4. While holding the wires flat between your thumb
and forefinger, insert the wires into the RJ45 con-
nector, so each wire 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 insu-
lation. It is necessary that the color scheme be
repeated identically on each end of the wire.
