Nuvo nv-a4ds-dc 사용자 가이드

  

The Simplese System uses Cat-5 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 Allport connection hub.

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