Technische Daten Air Base Extension - Loxone
DALI types 0, 3 and 6 are tested and supported.
DALI type 8 and DALI scenes are not supported.


  • DALI extension mounted on DIN rail
  • Do not power with 24V DC until the installation is complete
  • Connect Loxone link
  • Attention - The last device on the Loxone link will require a 120Ω resistor (included with the Miniserver)
  • Power up 24V DC power supply
  • Blink states of the device LED:
    Left LED flashes green after a few seconds if the DALI extension is already configured, orange if not.


  • The maximum voltage drop between the transmitter and actuator must not exceed 24V
  • The maximum cable length is 300m at 1.5mm2 conductors
  • For DALI installations both scheduled and star topology are possible, a ring topology must be avoided.
  • When using the maximum cable length it is not advised to install DALI in combination with power lines.

Power to the DALI bus

  • When an external power supply is used, the power for the DALI bus must be turned off in the properties of the DALI extension. Be sure to 'save in miniserver' to commit changes.
  • The voltage on the DALI bus is typically 16V
  • When external power supply is used be sure to observe correct polarity.

Configuring the Extension


To insert one or more extensions click in Loxone Config Software to "mini server" and then click "Search periphery" . Now the network is scanned and the Mini found servers are listed together with its connected Extensions in the search results window. Selecting a single extension, entering the "Name" and click on "Create device” will createa single extension. If you want to insert all connected extensions in the programming, just click on "Add All devices" . Here it is also possible to replace one device.

If several extensions of the same type are installed at the same time, they can be identified later by the software. Simply select a device in the peripheral tree of Loxone Config. The selected extension status LED will now begin striking blinking for a short time.


If no extension is connected to the Mini Server, they can not be found in the search. However, you can use those devices already in the programming. Connect with your mini server and download the existing program (if any) from the Mini Server. Click on the mini server in the periphery tree and then click ‘Devices’, From the drop down menu select an extension. All inputs and outputs for that device will now be available for use in the config. The serial number can be adjusted in the device properties.

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 You can find the serial number on the back of your extension. The number is printed underneath the barcode (see picture).

Extensions can also be replaced in the peripheral search. First, install the new extension and then perform the periphery search. Now the extension will appear in the list. Select device for substitution and click ‘replace device’ Finally save in to mini server to commit changes.


Select the DALI extension in the periphery tree and click the ‘DALI search’ button.

Gerät erstellen - Loxone
Additional functions in the search of DALI devices:
  • "Load factory settings" - The DALI devices are in the search to the factory settings.
  • "Complete new installation" - All DALI devices are in finding new Addresses If the DALI device already has an available short address, it will be deleted. All short addresses will be deleted and reassigned.
  • "Visual confirmation" - DALI device light up when they were found. If connecting to an existing DALI installation all devices and settings will also be found on the DALI search.
If a Dali installation is extended by a Dali-device, already installed address ranges will be taken in to consideration. In this free Dali addresses for the new Dali devices will be assigned. The condition is that the newly added Dali devices still have no address, otherwise there will be an address conflict. If in doubt, a search should be conducted with "complete reinstallation".
The additional options you typically use at a new installation or address conflicts
In a new Dali installation use the search option: "Complete new installation” so that Dali devices are assigned an address. If an address conflict is found between two or more Dali devices "complete reinstallation” should be executed. The Dali addresses are reassigned.
Highlight the device and enter a name, then oh click on "Create device”.

The DALI device will now appear in the peripheral window and can be used for programming. The following two items are available:
  • "Actor" = dimming value of the DALI device
  • "Fault" = Fault input of Dali devices 
With the fault signal lamp faults are output from Dali devices.  Possible Errors are no lamps used or defective lamps in the DALI device.

Selecting a taught in DALI device in the periphery tree will flash selected lights every 5 seconds. With this, identifying devices is easy.

In the properties of the DALI device you can adjust the following settings:

  • "Min / Max limits the DALI device" In the DALI search the minimum and maximum limits of the DALI devices are detected. These values ​​indicate minimum and maximum dimming of DALI devices. You can adjust the limits manually
  • "Dimming value at supply. This percentage is set when the supply voltage is applied. This value must be greater than the minimum limit and less than the maximum limit.
  • "Dimming on system failure" This percentage is set when a system error. This value must be greater than the minimum limit and less than the maximum limit.
  • "Increase" rate of change in percent per second jump means the target is driven immediately

Be sure to "Save In Miniserver” so changes are saved in the DALI devices.

Create DALI groups

Using DALI groups will allow control of multiple devices in parallel. This can be used for central functions for example.

When programming the DALI devices existing group assignments will automatically create groups.

To create a new group you must first learn in the new DALI devices.

In the properties of the group you can select all learned DALI devices.

The group actuator can now be used in programming.

DALI monitor

With the DALI monitor you can trace the communication between the DALI devices and the DALI extension. To activate the monitor, click the checkbox "Launch DALI monitor and display"


In the monitor next to the name of the device and the values ​​sent even the DALI commands can be seen. The DALI commands are defined in IEC 62386-102.

Here is an excerpt of the most important commands:



is dimming sent (0-255)



a record is retrieved from the DALI Dimmer

The following commands are used in the DALI search and addressing:





With SEARCH_ADDR_X the current Web address is set



Calls on the dimmer on to compare the own random number with the current search address



Dimmer found is subtracted from the search



the DALI short address is stored in the dimmer



the DALI short address of the dimmer is checked



Search operation is terminated
