Passphrase
The secured Wi-Fi connection has to be confirmed by a passphrase. This passphrase can
be seen and changed in the System Info (eective aer rebooting). Note that the pass-
phrase cannot be chosen, it will be randomly generated.
Free Internal Memory
The remaining free disk space is displayed in order to see, if the instrument is capable of
holding more presets.
Soware Version
For developers, the versions of integrated components is displayed as well.
Date / Time
The instrument contains its own system clock, which will be included in preset meta data
in the form of timestamps. It can be adjusted as well.
Update Available
The final menu entry is an indicator for an available update, if a USB stick containing that
update was plugged in. This can be used to test, if the update file is valid before actually
updating (see Notes on Soware Updates).
About [Hardware UI, Graphical UI]
In the About section, the Nonlinear Labs developer team is listed.
Backup
USB Available (Panel Unit only)
In order to backup all banks or restore a preexisting backup, a USB stick has to be plugged
in. The “USB Available” indicator shows if a USB stick is currently present.
Save and Restore
In order to save or restore all current present banks to or from a backup file, enter one of
these options. The backup file will be transferred to or from a present USB stick (if using
the Panel Unit) or it will be downloaded on your browser (if using a mobile device and
entering one of the provided context menus). The process may take some time, depend-
ing on the number of involved presets or banks.
߰ Details on how to save or restore backups on the Hardware User Interface and the Graphi-
cal User Interface can be found in chapter 4.13 Backups.
7. Updating the C15
߱ The included USB stick of the C15 package has a special format – other USB
sticks will not work for C15 updates.
New soware versions will be made available as downloads on the Nonlinear Labs web-
site. For an update of your C15 please follow the protocol below step by step:
1. Select the desired update in the download area of the Nonlinear Labs website:
www.nonlinear-labs.de/download/download.html
and download it to your computer.
2. Connect the USB stick which is included in the C15 package to your computer.
3. The downloaded file is a .tar archive file named “nonlinear-c15-update.tar”. Please do
not extract it. Instead just copy or move it to the top directory of the USB stick..
4. Switch o the C15 and plug the USB stick to the USB connector on the backside of the
Base Unit. Then start the C15.
5. An automatic update process will start, as indicated on the Base Unit Display. When
the shown status indicates that the update has finished, switch o the C15.
6. The USB stick can be removed now. Aer a successful installation, the update file on
the USB stick will have been renamed to „nonlinear-c15-update.tar-copied“. It should
be deleted before the next update.
When starting the C15 again, it will run the new soware version.
Besides, the C15 can display if a valid update file is found on the USB stick, which will be
useful prior to installing updates. This can be seen in the System Info section of the Setup
Menu, as there is an „Update Available“ entry at the bottom.
We recommend to always have the latest version installed, but it is also possible to down-
grade to a previous version by running the described installation process with the .tar file
for that version. However, preset compatibility is only guaranteed if updating to newer
versions. Presets created with a newer version may be corrupted when loading them with
an older version.
