Configuring Extension

To insert one or more extension select the miniserver in the periphary tree of Config Software and then click "Search periphery". This will search the Loxone link for all conencted extensions. To enter a single extensions, select the specific device, enter a name for it and the click "create device". Clicking "add all devices" will add all extensions to the config. It is possible to replace devices using the "replace device" button.



If you have installed several extensions of the same type and cannot identify which one is which (for example 2 DMX extensions) then you can use the software to identify a device. Simply click on the device in the periphery tree and the extension will flash red, green and yellow very quickly so you can identify it.

Extensions not connected

If there is no physical extensions connected to the Miniserver they cannot be found in the search. However you can add the extensions to the program so you can configure a system before installing. In the configuration software, connect to your Miniserver and download the existing configuration (if there is one) from the Miniserver.

Select the 'Devices' drop-down menu on the Periphery tab and select the required extension, then fill in the serial number in the properties.

Replacing Extentions

If an extension is replaced, the serial number in the properties must be adjusted. Click in the peripheral tree on the extension and go to the window "Properties".There you enter the serial number of your new extension.

Serial number
The serial number is on the back of your extension. You can find the number just below the barcode (see picture).

An Extension can also be replaced in the Peripheral Search.

Mount the new Extension and run the Peripheral Search. Highlight the Extension (not used) and choose the device you would like to replace in the drop-down menu.

Finally press "OK" and save your program into the Miniserver. The Extension has now been replaced.
