[. . . ] Start the same program on both PCs in order to transfer data back and forth afterwards. Shut down the operating systems of the PCs and turn them off (this automatically closes all open files). [. . . ] However, if a data transfer is taking place via the data link cable and you unplug the cable from the USB port, the PC might crash and damage data. If you plug-in or unplug the data link cable frequently, always plug it back into the same USB port, otherwise you might have to re-install the driver. With reverse sequence it may happen that the data link cable no longer works properly with the operating system. Please note: with new CD versions, the name of this directory may differ.

This means you can release folders or use printers jointly like with a common network. ) In addition, you can construct a small network with up to 17 PCs with several data link cables of the same type. Please observe that each PC must be turned on for this type of network ­ after all, there is no central hub/switch like with a common network. B) Data transfer mode (switch depressed, a bit further in the casing) Start the data transfer software installed with the setup program on each of the two PCs. [. . . ] Afterwards, there are two different programs available in the data transfer mode.
