What is the data line interface type
Data cable, its role is to connect mobile devices and computers, to achieve the purpose of data communications. Popular point that is connected to the computer used to send bell images and other documents of the access tool. Now with the rapid development of the electronics industry, the data line has become an indispensable part of our lives.
Sort by interface type
COM interface and USB interface
1, COM interface, also known as serial port, is connected to the back of the desktop computer, is currently being eliminated. Advantages are low prices, support Brush (some phones can only use the serial line brush machine); drawback is extremely difficult to pull, do not support the laptop, the transmission speed is relatively slow.
2, USB interface is the current mainstream, the advantage is convenient and fast and stable, support all models of the computer; drawback is with IC (central control chip) slightly higher prices, while some data lines do not support brush machine function.
USB interface data cable classification
Without IC (central control chip); with IC (central control chip); special chip.
1, without IC (central control chip): no central control chip, you must plug in the phone computer line, cheap.
Typical models: Samsung CDMA series, D500 series; Motorola E398 series, V3 series; Nokia DKU-2; NEC N720 series; Siemens 65 series and so on.
2, with IC: with the central control chip, the general model of the chip 2303,2101,3116, do not have to plug the computer will line, because the price of an IC is 10 yuan, so the price is more expensive than without IC. With the chip data line works is USB to COM, the USB interface into a serial port on the computer display.
Model: Samsung E638 series, D418 series; NEC N610 series; Siemens 25 series, 55 series; Sony Ericsson mobile phone data cable; Panasonic mobile phone data cable; Lenovo mobile phone data lines and so on.
3, special chips: non-ordinary popular chip, dedicated special models such as: DKU-5, CA-42, DCU-11 and so on.
