߰ If you encounter problems with your setup, there are some things you can do. If possible,
try to restart or change to another browser (or device). If not, or if the problem won’t
disappear, contact us directly. We appreciate feedback and reports of dysfunctionalities
and will try to solve problems quickly.
Wi-Fi Settings
In order to set all relevant aspects of a well defined Wi-Fi connection, enter the setup
menu on the Hardware User Interface (Setup button) and navigate to System Info. Here,
all relevant aspects of the Wi-Fi connection are listed:
Device Name You can give a name to your C15 instrument by focussing on the
device name entry and pressing enter, accessing the Rename
Screen. Once the name is set, an SSID will be generated. The SSID
is composed of a prefix (“NL-C15-”) and the name you just gave to
the instrument.
SSID A Wi-Fi network with the same name as the SSID will be provided
once you scan for available networks on your external device.
When connecting to this network, your external device will be
able to control the C15 over a browser. The SSID is generated
once during the booting process, so renaming your device will
require restarting.
Passphrase The network connection is secured, so a passphrase is needed in
order to establish a connection. When connecting to the network
from your external device, use the displayed passphrase to
confirm. The passphrase can be randomly generated by focussing
on the corresponding entry and pressing enter. The command
“generate new” has to be selected and executed. If you suspect
that the passphrase isn’t secure anymore (because it has been
shared with someone), a new passphrase should be generated.
Address 192.168.8.2
Once the connection is established, post and submit the address
into your browser’s address bar and the Graphical User Interface
should appear in your browser.
߰ If you encounter problems navigating the Setup menu intuitively, please refer to chapters
4. User Interfaces and 6. Setup (C15 System Settings).
2.4 Setting up a Device for the Graphical User Interface
Concept
The C15 is designed to be of flexible usage and interaction, requiring at least the Base
Unit for connections and performance. In addition, the Panel Unit provides the Hardware
User Interface and therefore access to all parameters, presets and settings.
Finally, the Base Unit also provides a Wi-Fi hotspot in order to connect external devices,
such as smartphones, tablets, laptops and desktop computers. When connected, the
Graphical User Interface can be accessed by using a browser from the external device.
Multiple external devices can be connected simultaneously, each capable of showing
dierent features. However, only one parameter can be focussed at a time, synchronizing
the Hardware User Interface with every connected external device.
Furthermore, the Wi-Fi connection allows for preset interchange and therefore the
possibility of backing up preset banks to the external device. The C15 User Manual is also
accessible in the browser.
System Requirements
Due to the browser-based implementation of the Graphical User Interface, there are
almost no limitations concerning compatibility between operating systems or browsers.
Basically, the only required device functionalities are the device being capable of a Wi-Fi
connection and an installed browser.
However, in the wide variety of devices, operating systems and browsers, there may be
some restrictions and optimal performance can not be guaranteed. Dierences between
browsers, fast technological advances and frequent updates contribute to a complex
situation, in which it is increasingly hard to state what is suitable.
Nevertheless, there are some experiences that emerged during development and can be
expressed as a recommendation, or understood as minimal requirements:
• The device should run at least with a 1 GHz processing unit and 2 GB RAM space.
• The device display should support multi touch, or a mouse should be connected. A
connected or integrated keyboard is useful in the Graphical User Interface.
• The device display should span at least 7’’ diagonally.
• Although the choice of the browser is completely up to the user, currently (Decem-
ber2018) the best performance is achieved by using a Google Chrome browser.
