CNXT smart - The service that connects it all.

Thanks to CNXT smart, all your Rodenstock measuring devices (DNEye® Scanner 2 / 2+, ImpressionIST® 4, Rodenstock Fundus Scanner) as well as your software (industry software, Rodenstock Consulting or WinFit Reference®) are fully connected.

The transfer of the measurement data takes place automatically and in real time. The customer data relevant for analysis, evaluation and lens consulting are therefore immediately synchronized on all devices and available at any time. The highest security standards, such as absolute data security and data availability are of course always ensured.

By synchronizing measurement and customer data, you benefit especially from time savings, reduction of typing errors and availability of your measurement data on all end devices.

With CNXT smart you can only win - above all, more time for your customers.

The result

Your data is always available on all devices - absolutely secure. This gives you more time for your customers and more detailed advice that sets you apart from the local competition.
This is the experience Ralf Propson from Colibri Contactlinse und Brille GmbH in Lübeck and many others have already made:

"The new Rodenstock platform CNXT smart helps us save time in our daily work. The structure of the CNXT app is very clear and intuitively designed, so that we can manage our customer data even more efficiently and therefore have more time to advise our customers optimally.“

    *Operating Systems
    • From Windows 10
    • From iOS 13.0
    Smartphone use is not supported.

  • New hardware is only necessary if no suitable PC is available for this task.
    CNXT requires a Windows 10 PC that manages the connection to the CNXT server and is switched on during the shop's hours of operation.

    For the use of a full featured CNXT, an Internet connection is needed. We recommend an Internet connection with at least 10MBit/s data transfer rate.
    In case of an interrupted Internet connection, CNXT still allows easy local data transfer between devices and applications. (e.g. Rodenstock Consulting, WinFIT Reference®).

    CNXT runs on these operating systems:
    • From Windows 10
    • From iOS 13.0
    Smartphone use is not supported.
    If your hardware does not support these versions, please update them.

  • Yes.
    CNXT provides an interface, which can be used by software houses to exchange data with CNXT.
    Functioning interfaces (Germany):
    • Deutsch & Heckelmann
    • IPRO
    • OPA
    If the software house provider of the ECP is not listed here yet, he /she should contact them directly and ask the provider if the connection to CNXT has already been implemented.

  • Is CNXT data protection compliant?
    Yes. Our top priority is to provide all data processing with a focus on security, protection and availability. The General Data Protection Regulation (GDPR) of the European Union, which raises and harmonizes the standards for data protection, security and compliance with its strict requirements, fulfills the CNXT platform.
    You can find more information on this directly within the CNXT application in the Trust Center.

    Where are customer and measurement data stored?
    1. CNXT data - the sum of all measurement results combined with additional data (e.g. subjective refraction) - is stored on provided servers, located at SpaceNet AG in Munich, Germany.
    2. As usual, the full data of your Rodenstock measuring devices and applications are still stored locally on their databases.

    Why is the data stored at SpaceNet AG and not locally?
    CNXT is a state-of-the-art software. To get all the advantages of it and provide the best service to our customers, the platform is operated online.
    Advantages for the ECP:
    • No additional hardware required
    • Automatic data updates
    • Automatic data backup through a highly available database at SpaceNet AG. As usual, the full data of your measuring devices and applications are still stored locally on their databases.
    • Data availability from different branch shops / stores

    SpaceNet AG is a long-standing provider of online solutions and brings a lot of experience in data security to CNXT.

    Is data transfer between the ECPs´ shop and the SpaceNet AG server protected?
    Yes. CNXT has an integrated security concept, from the connected systems to the CNXT servers.

    Is the connection and data transfer between CNXT and software house (management software) secure?
    Yes. CNXT has an integrated security concept, from the connected systems to the CNXT servers.

    Are 100 % of the measured values from DNEye® Scanner 2/ 2+, Rodenstock Fundus Scanner, ImpressionIST® 4 stored in CNXT?
    CNXT stores final measurement results. This is necessary for ordering (lens orders, telemedical analysis) and some data is useful for visualizing measurement results.

    e.g. ImpressionIST® 4 stores the individual parameters, centration and shape data, as well as reduced-resolution images in CNXT.
    The position of selected elements for an ImpressionIST® 4 measurement is not stored in CNXT.
    The measuring devices store all data locally as ever before.
