Installing the Grand Concerto System in Your Home
I. CAT5 Termination
The Grand Concerto System uses CAT5 cable for Control Pad control and either two or four-conductor 16-gauge speaker wire. All
the wire is “homerun” from each zone to the location of the Grand Concerto amplifier and Audio Source equipment.
Complete CAT5 Crimping Instructions
The NuVo audio systems require CAT5, unshielded, twisted
pair (UTP) for communication between the Control Pads and
the main amplifier unit. Each end of the wire is terminated
with an RJ45 connector.
The Grand Concerto System can accommodate 2,000 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 test each end to end run with a
CAT5 wire tester to insure that your system operates
flawlessly, Fig.1.
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.
7. Test each termination with a CAT5 Tester before
completing the installation.
