1、Overview

Current computer 's USB port has become commonplace , USB2.0 theoretical transfer rate of up to 480Mbps, ie 60MB/s, USB3.0 theoretical transfer rate of up to 5Gbps, ie 625MB/s. Currently the USB port is mainly used for U disk, USB hard disk, USB keyboard, USB mouse, USB camera , USB CD-ROM、USB DVD drive, etc.

In fact, with a USB data link cable using the USB port can also achieve USB-based internal and external network isolation,USB pc to pc communication, USB point-to-point communications, USB point-to-multipoint communications, USB-based small-scale distributed server, USB file transfer, USB CD-ROM sharing, HD data sharing, HD data sync, network sharing, KM(key/mouse) sharing, clipboard sharing, file sharing,etc.

USB data link cable also called USB transfer cable, USB easy cable, USB shared cable, USB connection cable, USB interconnection cable, USB copy cable, USB networking cable, etc.

Typically, USB data link cable are configured dedicated software. These cables are not providing application programming interface (API), with them developers can not implement their own applications, for example: internal and external network isolation, USB communication, USB file transfer, USB data sharing, USB device sharing, etc. For the needs of developers, Shijiazhuang ZhongZhi Electronic Technology Development Center has developed a USB data link cable application programming interface (API), and provide support for developers to develop their applications.

USB data link cable API provide usb host to usb host transparent transmission, users can develop a variety of itself with its. Such as: encryption transmission, the internal and external network isolation etc.. For the internal and external network isolation , two PC data transmitting and receiving totally self control, and has high security, akin to physical isolation completely, but more convenient to use than the physical isolation.

DESCRIPTION:
    Empty the transmit and receive buffers

3AboutUSBdata linkcable

USB data link cable and ordinary USB cable are different, there is a chip in data link cable middle. Because the USB bus system can have only one host, usually the computer's USB port are the host interface, so you can not simply connect them together. A transformation is needed between PC USB port and PC USB port, the chip in the middle of  cable is to complete this conversion, this has a USB data link cable generation. There is a small pimple in the middle of a USB data link cable, or one end of USB data link cable is similar to the U disk, and some cable itself can also be used as U disk.
1 USB cable linknetworking cable = 2 net card + 1 net wire, and the rate is much faster than the network card, and can isolate viruses, network attacks, very safe.

   
USB data link cable applications:
  • USB point-point communication
  • USB point-to-multipoint communication
  • Internal and external network isolation
  • Small distributed server
  • High speed transfer files or copy files between two computers
  • Synchronize files or documents between two computers
  • Sharing IP Internet (without card, through another computer on the Internet)
  • Shared device(For example: keyboard, mouse,CD-ROM,DVD,etc.)
  • USB file transfer, USB data transfer
