The USB interface is a standard serial interface.
(USB = Universal Serial Bus)
Various USB devices, such as mouse, external hard disks, and USB memory
sticks, can be connected to the iTNC via the USB interface of the MC 6xxx.
The USB interfaces of the MC 6xxx support USB 2.0.
Note
If USB components require more than 0.5 A, a separate power supply
becomes necessary for these components. One possibility is the USB hub
from HEIDENHAIN (368 735-01).
The USB interface features "hot-plug capability." This means that you can
connect USB devices to the USB interface and remove them, without having
to shut down and then restart the control.
Transmission distance without hub: Up to 6 meters
Note
For greater transmission distances, you must use a USB hub after every six
meters in order to amplify the signal. You can use more than one hub for
one transmission distance. USB cables with a length of up to 36 meters
(with 6 integrated USB hubs) are available from HEIDENHAIN:
