USB devices on the TNC
Backing up data from or loading onto the TNC is especially easy with
USB devices. The TNC supports the following USB block devices:
„ Disk drives with the FAT/VFAT file system
„ Memory sticks with the FAT/VFAT file system
„ Hard disks with the FAT/VFAT file system
„
CD-ROM drives with the Joliet (ISO 9660) file system
The TNC automatically detects these types of USB devices when
connected. The TNC does not support USB devices with other file
systems (such as NTFS). After connection, the TNC displays an error
message.
The USB devices appear as separate drives in the directory tree, so
you can use the file-management functions described in the earlier
chapters correspondingly.
In order to remove a USB device, you must proceed as follows:
8 To call the file manager, press the PGM MGT soft key.
8 Select the left window with the arrow key.
8 Use the arrow keys to select the USB device to be
removed.
8 Scroll through the soft-key row.
8 Select additional functions.
8 Select the function for removing USB devices: The
TNC removes the USB device from the directory tree
8 Exit program management.
In order to re-establish a connection with a USB device that has been
removed, press the following soft key:
8 Select the function for reconnection of USB devices.
The TNC also displays an error message if you connect a
USB hub. In this case simply acknowledge the message
with the CE key.
In theory, you should be able to connect all USB devices
with the file systems mentioned above to the TNC. If
problems occur nevertheless, please contact
HEIDENHAIN.
