  • Control up to 128 DMX lighting channels
  • 2-wire bus for connecting to other devices
  • DMX-512 protocol support
  • Loxone Link for connecting to the Miniserver
  • Compact housing for rail-mounts
  • Dimensions: 34 x 85 x 49 mm (2 TE)
  • Minimal power consumption
  • Power requirements 24VDC
  • Protection: IP20
  • Ambient temperature: 0 to 50°C
Technical Data


  • Mount DMX Extension on the DIN rail
  • Connect 24VDC power supply, but do not switch on until the whole installation is completed
    (We recommend looping power through the Miniserver)
  • Connect to the Loxone Link
  • Connect the DMX connector to a DMX control device
  • Note: If it is the last extension, terminate the Loxone Link with a 120Ω resistor
    (Included with the Miniserver)
  • Turn on the power supply
  • After a few seconds, the left LED will flash green if the DMX Extension is already configured, or orange if not

General notes on wiring

  • Use Cat5e cable, though depending on the installation conditions shielded Cat5e cable should be used on longer cable runs (in excess of 50 metres)
  • The cable must not be longer than 500 metres
  • The DMX cable must go from receiver to reciever (daisy chained i.e. bus topology)
  • The Loxone Link must be terminated with a 120Ω resistor

Configuring Extensions

Extensions are connected to the Miniserver with Loxone Link

To add one or more extensions to the program the simplest way is to connect up the extensions to the Miniserver using the Loxone Link and looping power. Then do a search in Loxone Config, which will bring up the Miniserver and all the connected extensions. You can highlight a single extension, give it a name and then click Create device which will add in the highlighted extension. Or you can click on Create all devices which will add all the connected extensions in to the program with the correct serial numbers.

Extensions are not connected to the Miniserver

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.

Entering a serial number

If you are manually adding devices before the Miniserver install has been done, or if an extension has been replaced you need to add the serial number in the properties. Click on the extension in the periphery tree. Enter the serial number of the extension in the properties section. 

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

Save the configuration in the Minisever

After entering your extension's serial number, click on the Miniserver tab and select 'Save in Miniserver'. The controller reboots and after about 10 seconds, both status LEDs on the extension will turn green.

Identify device

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.

Insert a DMX actuator

Add a DMX actuator found in the Periphery tab. Depending on what DMX device you have will effect your choice of type of actuator. If you are controlling RGB tape or lights using a DMX driver then choose 'DMX RGB actuator'. If you are using single colour strips then add 'DMX actuator'.

DMX channel adjustment

Adding DMX actuators will automatically assign channels, so for example if you add two DMX RGB actuators the first one will be channel 1 and the second will be channel 4. 

To reassign the DMX channel go to the appropriate (DMX actuator / DMX RGB actuator) 'Properties' window, and enter your selection. Then save the program in the Miniserver.
