Nuvo NV-18GMS Manual De Usuario

  

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.

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.

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.
