Nuvo NV-I8GMS, NV-I8GXS manual Installing the Grand Concerto System in Your Home

Installing the Grand Concerto System in Your Home

I. Prewire

The Grand Concerto 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 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 keypads/Display 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.

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.

7.Test each termination with a CAT5 Tester before completing the installation.
