5.5 The quInfo Module
Backup: In addition you can backup the software in this tab to a USB ash drive. Simply
plug in the ash drive and give it some time to be mounted automatically. Then hit the
Backup button. This will copy the currently installed version of the quTouchv2 software
to the ash drive. Please ensure that the backup was successfully written by looking into
the stick from a computer.
Update: In case you want to update
or restore the quTouchv2 software, please follow
these steps:
Make a backup of the currently installed version as described Above.
Copy the new version of quTouchv2 to the root directory of an empty ash drive.
In case you want to restore an earlier backup, rst rename it to quTouchv2. If the
update comes as a zip archive, please extract the content to the root directory of
the drive and make sure the directory structure is maintained.
Turn o the controller and plug in the prepared ash drive.
Turn on the controller. The system should now start with the update process and
run the quTouchv2 software directly from the ash drive. This is indicated by the
message evaluation-mode in the top left corner of the display. For a more involved
updates, in order to arrive at this state it might be necessary to turn the controller
o and on again with the ash drive attached.
You can now evaluate the software without any restrictions. Additionally, in the
info tab, the md5 checksum of the running binary is displayed. Please compare it
to the value provided with the update to verify the integrity of the binary.
While in evaluation mode the info tab displays an update button. If you nally
want to make the program version currently running from the ash drive permanent,
hitting this button will copy the binary from the ash drive to the controller memory.
A message requesting a reboot is displayed afterwards. Please remove the ash drive
and hit restart.
After this process, the new or restored version is installed permanently. Please remove
the update les from the ash drive in order to avoid starting in evaluation mode in the
future when using the drive with the controller.

This tab is used for changing the expert mode pass phrase (see gure
). It has to
be composed of 4 distinct circles and the order in which they have been touched. The
changed pass phrase will be saved immediately after you clicked the last (4th) circle of

restart button described in section
. In case you pressed an unwanted circle you can
restart typing the new pass phrase by pressing the reset button. If your last circle was
