Data cable, which is used to connect mobile devices and computers for data transfer or communication purposes. Popularly speaking, it is a access tool for connecting computers and mobile devices to transfer files such as videos, ring tones, and pictures.
Now, with the rapid development of the electronics industry, data lines have become an indispensable part of our lives.
Classified by interface type
COM interface and USB interface
1, COM interface is also called serial port, is connected behind the desktop computer, is currently being eliminated. The advantage is that the price is low, and the brush machine is supported (some mobile phones can only use the serial cable to brush the machine); the disadvantage is that the removal is extremely inconvenient, does not support the notebook computer, and the transmission speed is relatively slow.
2, USB interface is the mainstream, the advantage is convenient and fast and stable, support all models of the computer; the disadvantage is that the price of the IC (central control chip) is slightly higher, and some of the data lines do not support the brush function
Functional classification
Internet cable; brush line; sync line; charging line; multi-function line.
1. Internet cable: It can only be used for GPRS or CDMA 1X Internet access. Typical models: V730 series; V688 series; PHS series.
2, brush machine line: can only be used to upgrade the brush machine. Typical model: BenQ S700; upgrade to unlock the first line.
3, synchronization line: used to transmit phone book; picture ringtones; text messages; multimedia materials, etc., of course, some are two-way transmission, some only support one-way transmission. Such data lines are more common.
4, charging cable: generally the Internet cable or sync cable plus a USB charging function, more practical and convenient, Internet and group messaging essential features. It can also be subdivided into two types: charging and charging. The former is charged as soon as it is plugged in. The latter has a small switch that controls whether or not it is charged. Of course, the highest level with the charging switch, the price is more expensive. Recommended type: CDMA Internet series; Siemens 3508 series.
5, multi-function line: at the same time support Internet, synchronization, brushing, charging and other 2 or more functions, the new Samsung line is also equipped with dual interface, USB synchronous Internet; serial brush machine.
Reminder: When you buy a data cable, you must have more functions. The better, it is more expensive, so it is equal to the multi-line.
Generally, there are few dedicated data lines. The common phenomenon is that one data line can be used for a variety of mobile phone models. Some models have more exaggerated data lines, and one line can use 30-40 different types of mobile phones.
The problem commonly encountered by data line vendors is that the customer reflects that the data line cannot be used. If you are sure that the shipment has not been made wrong, most customers will not use the data cable. First look at the software inside the CD to support the customer's mobile phone model, if you do not support you can go online to download a corresponding software, so the general problem will be solved. The key point is that the data lines are universal and the software is not universal. There is no particularly good way, after all, there are too many mobile phone models.
