How to wire
Cat5 cabling.
One of the new technical terms to describe
the cabling necessary to allow integration of audio, video, data
and voice throughout the home.
Beware of
contractors that will advertise "cat5 wiring" who are simply
using a single cat5 to connect all locations. This type of
wiring, although it may be "cat5" will not enable the features
of true structured wiring. True structured wiring requires
multiple cables and the knowledge to terminate and interconnect
these wires to produce the desired results.
Structured wiring incorporates two category 5
cables and two RG6 cables in each room of the home. One category
5 is for telephone and one for computer networking. The RG6 is
used to distribute video in both directions, in or out of the
room. All wiring is routed back to a hub panel, where
connections are made to each room.
Additional wiring can be used to provide audio
and infrared capability in each room. This cabling consisting of
a 4/16 or 4/14 cable to carry audio to wall speakers in each
room and a category 3 cable to provide infrared to change CDs or
radio stations and volume.
This combination of wires enables any
combination of technology to be routed in or out of any room in
the house. Having all wires labeled and available in a hub,
makes changing the configuration very easy and convenient.
To complete the recipe of wires, add one
category 3 to a location for a motion sensor and an RG59 with
22/4 shielded cable for cameras.
This makes it possible to program an
automation system to control lighting, heating, A/C and
security.
- Whenever you enter a room, the light will
go on if it is after sunset, and shut off 10 minutes after you
leave.
- Children can be monitored on any TV in the
house.
- CD music or radio tuner can be listened to
in any room with volume control and selection capability from
any room.
- Pick up any telephone to:
- Change the thermostat setting
- Answer or unlock the door
- Shut off any individual light or all the
lights in the house
- Open or close the blinds
- Announce the presence and light the way for
a visitor as they enter the driveway
- Automatically turn the heat down when no
one is in the house and raise it back when you arrive
- Call ahead and turn the heat up or down
- Unlock your door from the office for a
contractor
- Be paged when a child returns home from
school
- Automatically record activity around the
house when the alarm is armed
- Announce the delivery of mail
- Access files on any computer from any other
computer in the house
- Connect to the internet from any room in
the house
- Listen to different music in each room
- Shut off all of the lights in the house
with one button
- Give the house a lived in look when not at
home
10BaseT Ethernet:
The most popular method of connecting computers
to each other in the home and office. Data
travels at 10 Mega-bits per second (and there
are 8 bits per byte, so 10Mb = 1.25 Mega Bytes/s).
The RJ-45 Plug at each end is like a phone jack,
but wider. The wire used is (generally) Cat-3 or
Cat-5. If you are running a 10BaseT network,
Cat-3 wire is cheaper and works fine. If you
have 100BaseT ethernet cards installed, Cat-5 wire
is better. These wires have pairs of wires
twisted together to reduce inductance, resistance,
etc.
Straight-through:
CRIMP 1 on both ends.
Used to hook computers to Hubs.
Cross-Over:
CRIMP 1 on one end and CRIMP 2 on the other.
Used to hook one hub into another hub.
Also used to directly connect two computers.
Tool:
You need a crimping tool which is made for
crimping RJ-45 jacks. Usually, you can find
one that can does RJ-11 and RJ-22 as well.
RJ-11 is the jack size for your telephone.
RJ-22 is the phone to headset wire.
RJ-45 = 8 wires (10 wide, only 8 used)
RJ-11 = 6 wire jack (with only 4 used)
RJ-22 = 4 wire jack
Cat3 is okay for 10BaseT
adequate for networks with up to several dozen computers sharing a DSL line
This wire is cheaper that cat5 wire
What is CAt6 cable?
Definition:
CAT6 is an Ethernet cable
standard defined by the Electronic Industries Association and
Telecommunications Industry Association (commonly known as EIA/TIA).
CAT6 is the 6th generation of twisted pair Ethernet
cabling.
CAT6 cable contains four pairs of copper wire and
unlike CAT5, utilizes all four pairs. CAT6 supports Gigabit
(1000 Mbps) Ethernet and supports communications at more than
twice the speed of CAT5e, the other popular standard for Gigabit
Ethernet cabling.
As with all other types of twisted pair EIA/TIA cabling, CAT6
cable runs are limited to a maximum recommended run rate of 100m
(328 feet).
Twisted pair cable like CAT6 comes in two main varieties,
solid and stranded. Solid CAT6 cable supports longer runs
and works best in fixed wiring configurations like office
buildings. Stranded CAT6 cable, on the other hand, is
more pliable and better suited for shorter-distance, movable
cabling such as "patch" cables.
CAT6 comes at a significantly higher price tag than CAT5 or
CAT5e, and today's applications simply can't take advantage of
CAT6's better performance. However, if wiring a home or building
for the long term, one may still consider using CAT6.

HowTo WireCAT5
Description
Here are the steps to wire CAT5 Patch
Cables – for most installations use Standard Patch Cable A.
Steps
1) Strip
the cable jacket back about 3/4 of an inch from the end of the
cable
2) Sort
the pairs so they fit into the connector in the order shown on
the diagrams below
3) Insert
the pairs into the connector
4) Crimp
the pins with a crimp tool
5) Repeat
for other end and test cable
*Use stranded
wire for category 5 patch cable
**DO NOT UNTWIST ANY PAIR MORE THAN 1/2 INCH

Here is an excerpt from
csp.com:
CAT3:
Intended for older network traffic and phone systems where the
frequency performance is less important. Commonly, CAT3 cable is
used in older 10BaseT and Token Ring network infrastructures,
and for telephone premise wiring.
CAT5:
Ratified standard for unshielded twisted pair. Handles voice or
data at 100MHz over 22 or 24 AWG wire. Used for high-speed
twisted-pair networks such as 100 base-TX, fast ethernet.
CAT5e:
More stringent specifications than CAT5. CAT5e has a higher
rating, 350Mhz vs 100Mhz for CAT 5...it also provides better
performance. Cable manufacturers have improved the cabling,
connectors and patch cords of regular CAT5 to provide an
improved attentuation-to-crosstalk ratio (ACR), and to meet or
exceed all the parameters of the CAT5e standards approved by the
Electronic Industries Association/Telecommunications Industry
Association (EIA/Telecommunications Industry Association) and
the Institute of Electrical and Electronics Engineers (IEEE)
