DIVUS FAQ.

To configure, connect remotely to the KNX CONTROL device. Open Google Chrome and go to the device's local IP address shown in the project, router or display. If a certificate warning appears, confirm it to go to the interface.

The default login is username admin and password admin. Then use the admin button at the bottom right to open the administration menu and start the project configuration there. You can find the appropriate administrator manual centrally in the KNX Control download area.

First check the KNX bus connection: correct wiring, bus voltage, polarity and possible address conflicts. The standard physical address of the KNX CONTROL device is 0.0.255.

If telegrams are blocked by line or area couplers, a dummy object for the KNX CONTROL device must be created in the ETS and adopted into the filter tables of the couplers.

In the case of one-way communication, you also check whether control objects and feedback are connected correctly. If there is no response, an object can send but does not update itself. If communication still does not work after this, first backup the project and contact technical support.

For local access, the device can act as a communication interface of type KNXnet/IP be set up in the ETS. To do this, enter the IP address of the KNX CONTROL device manually.

A VPN connection to the local network is also required remotely. In addition, access data for the ETS gateway must be created in the administration menu and the necessary router access must be properly configured. The exact procedure can be found in the administrator manual KNX Control download area.

All current tools, software packages, firmware files and technical documents are stored centrally in the Download area maintained. Use the filters based on area, product and document type.

Manuals, quick starts, data sheets and further technical information can be found in KNX Control download area. This means that the documents remain up-to-date in one place and do not have to be maintained separately on each product or FAQ page.

Basically, the files in the download area are intended for the current hardware and software generation of the respective product. Projects created with a newer PDK version cannot be transferred to devices with an older software version.

For KNX CONTROL devices from production date April 2016 with OPTIMA 2.x, use the current documents and packages KNX Control download area. For older devices or an unclear production generation, support should be contacted before the update to ensure that incompatible packages are not installed.

KNX CONTROL devices with production dates up to March 2016 cannot be updated to OPTIMA 2.0 or higher. An update attempt with new packages results in an error message and is aborted.

The appropriate 1.3.x generation remains relevant for these devices. Since older packages should no longer be maintained across multiple pages, they are made available via the central download area or directly via support.

Drag & Drop means pulling and releasing. In OPTIMA, this principle is used to connect KNX objects with feedback, assign objects to rooms or adopt elements in scenarios and logic.

To do this, open the search function, locate the desired object and drag it into the designated area. From OPTIMA 2, drag & drop also works directly from the configuration menu.

Some configuration pages are higher than the browser window. In this case, a scroll bar appears on the right. Alternatively, you can scroll with the mouse wheel or trackpad to reach the rest of the page content.

Image files are scaled or displayed at their original size depending on the view. For the home screen, the image should match the target resolution as closely as possible to avoid scaling artifacts and unnecessary load.

In background views, the image is displayed in its original size. If it is smaller than the screen, the remaining space remains free; if it is larger, only a section is displayed. Fixed image areas apply to grid views. Therefore, make sure you find a good compromise between quality, resolution and file size. JPG and PNG are recommended.

OPTIMA applies changes immediately, but does not immediately write them to the device's flash memory. To protect the memory, storage takes place automatically at intervals.

If there is unsaved data, the save button in the administration menu will be displayed in red. You can then save the data manually.

OPTIMA contains technical documentation, notes and help texts directly in the interface. Many pages offer additional explanations about the current function using the question mark symbol.

If you still get stuck, please send support as specific information as possible: product, software version, affected area, screenshot and short description of the error.

OPTIMA stores a lot of content in the browser cache. Changes will therefore only become visible on other devices when the interface is updated.

In OPTIMA, use the sync symbol at the bottom right or perform a refresh via the settings in the OPTIMA app.

If your device is already running OPTIMA 2.2 or newer, the online update mechanism can be used. Open the administration, switch to the basic view, go to the update page and start the update button.

Before each update, the database, images, scripts and existing energy values ​​should be backed up. After a successful update and restart, the local browser cache should also be deleted.

As of OPTIMA 2.5, first generation DIVUS TOUCHZONE devices are no longer technically supported. The update procedure to this version is therefore only useful manually and only for suitable devices.

Before updating, check the generation of your device and only use the appropriate documents KNX Control download area or contact support.

Matching packages are no longer linked directly in FAQ answers. Use the central one KNX Control download area and check the product, version and document type there.

With OPTIMA 1.x, the correct update path depends heavily on the initial version and device. Devices with very old OPTIMA generations cannot be updated to the current generation.

Do not install unclear or old update packages without checking them. For OPTIMA 1.x, contact support with product, serial number, production date and current software version.

Product name, serial number or version, production date if known, software version, a short description of the error, affected area and screenshots are helpful. If you have any questions about updates, also specify the current OPTIMA version and the target update.

Take advantage of that Contact form with support selection. This means that the request ends up directly in the appropriate channel and can be assigned more quickly.
