RJ45 connector

Function connector: Easily the replacement aircraft for telephone or facilitate removable and easy to be revoked without fear stung by the flow of electricity
If installed in accordance with installation instructions will save the phone bill up to 30%. By using this tool it will get an added value to communicate. jack (RJ) is a network of physical standards - both in construction and wiring pattern jack - to connect the telecommunications, data or equipment (commonly, a telephone jack) or computer networking equipment to services provided by local exchange service, long distance service, or network data in the case of a RJ-45 connector.

Technique is the cheapest and most satisfying is to use UTP cable. UTP cables are unshielded Twisted Pair stands, is the cable consisting of 4 pairs (blue, orange, green, and brown) wires are twisted according to certain rules and are used to transfer / receive data.
his cable consists of several types of

1. Cat 5 UTP, 100Base-T technology, the frequency of 16 MHz. Data bandwidth up to 100 Mbps (theoretical) .
2. UTP cat 5e, 1000Base-T technology, the frequency of 100 MHz. Achieve data bandwidth 1000 Mbps (theoretical) .
3. UTP cat 6, 1000Base-T technology, the frequency of 250 MHz. Data bandwidth to 2,500 Mbps (theoretical) .

rimp tools / Crimping tool is a tool for installing UTP cable into the RJ-45 connector / RJ-11 depending on needs. Various shapes is large with many functions, such as can cut the cable, peeling and so on. There is also the only dedicated to Crimp RJ-45 or RJ-11 only.

For the type of cross was used to connect directly between two PCs, or are generally used to connect between the hub. How to install also really easy, just like a straight type, pin is used also only have 4 pins, namely pins 1, 2, 3 and 6. What is different is the way pair. If the type of cross, pin 1 is connected to pin 3 on the other end, pin 2 to 6, pin 3 to pin 1 and 6 to 2. Practical way, at the end of the first pin you can set up standards for the type of "straight", whereas in the other end of the pin you set up standards for the type of "cross". Still confused? Here's how easy it is: The first tip:

1. young orange
2. old orange
3. green
4. blue
5. navy
6. dark green
7. brown
8. sepia

So at the other end must be made :

1. green
2. dark green
3. young orange
4. blue
5. navy
6. old orange
7. brown
8. sepia

It's a little more understanding? So here's position number 1, 2, 3 and 6 are exchangeable. Later when tested using the LAN tester, then later led 1, 2, 3 and 6 will be exchanged. If the type of straight running sequence, while there are cross type jumping. But who would have each led is lit all of the numbers 1 to 8.OK, congratulations to build computer networks.
