Internal device connector Lightning in iPhone 5

As with most of the functions of the iPhone 5, the new smaller connector Lightning was known even before the official presentation of the smartphone. True, the blurry picture was hard to understand the new interface - it's not just a compact version of the traditional 30-pin port Apple. The new cable-sided, and a new feature that will add a company that will pay users.

Connector Lightning - an 8-pin standard, but each cable - 16 pin. Thus, as if you did not connect it to the iPhone 5, you get the first time. How is it, told in detail in the publication PCWeek, and it appears that everything is much more complicated than it seems at first glance.

On each side of the Lightning - contacts, numbered from 1 to 8. By checking the experts found that the first top port provides power via USB, and the connectors are symmetrical, that is, the eighth performs the same function. So, if you turn the plug, the contact for the supply will still be in place.

Contact data, however, are quite different, they are asymmetric. That is, if you turn the connector, then they would not be in those places where it is necessary. For example, if you look at the second bottom "pin" for the data, it is electrically connected to the second from the top. So, when you turn the plug, cable ends connect with the wrong contacts smartphone.

Experts attribute this strange circumstance as follows: iPhone 5 dynamically assigns the function "pins" with a special chip inside the phone. Apple said that the connector Lightning uses only the contacts that are needed for specific applications, and accessories. iPhone 5, apparently checks the type of transmitted data and change settings on the fly.

As a result of all this, you can connect the Lightning as you want, and this connector has room for growth in the future. But the complexity of the interface can be explained by the authentication chip inside the cable. It is located on a wire V +, so that without it the cable will not work.

If you think you can easily get a cable from Apple, you need, then you are wrong. Companies do not have enough cable Lightning, and most likely due to the fact that produced them are scarce. Not only because of the difficulties in manufacturing, but also because the cost is much higher than the old 30-pin version. Analysts estimate the cost of Lightning in 3.5 dollars, which is 775% more than the traditional 30-pin cable.
