The Loxone Miniserver serves as central control unit for all kinds of automation tasks.
The replaceable microSD card contains the operating system as well as the user programming and settings. The LAN interface is used for programming and the integrated web server allows the control of the system via a web interface or the Loxone App.
It features 8 potential free relays, 8 digital inputs and 4 analogue inputs (0-10V). Up to 30 Extensions can be added to the Miniserver via the Link interface to add additional functions such as inputs, outputs or interfaces.
A Loxone Tree interface is also integrated to connect sensors and actuators throughout the building.

The Miniserver is installed on a DIN rail in a suitable enclosure.
Connect the power supply, as well as inputs/outputs and interfaces, if applicable.
Via the LAN port the Miniserver is connected to the local network or a WiFi router.
The Miniserver starts after the power supply is turned on, and will be operational within a few seconds.
Once the boot up process is complete, the left status LED will blink green once every second.
The right LED indicates whether any System Status messages are available.
At first startup with factory settings, the Miniserver is assigned an IP address by the router via DHCP.
If there is no DHCP server in your network, or if the Miniserver is connected directly to a PC, link-local addressing via Zeroconf is supported.
If both Miniserver and computer are set to DHCP, they will use a 169.254.x.x link-local address.
Alternatively, you can manually assign a static IP address to the Miniserver and computer to enable a direct connection.
You can then search for the Miniserver in Loxone Config and connect. The factory settings for user and password are: admin/admin
Then follow the instructions for the Initial Setup to create your new project with the Miniserver.
Up to 30 Extensions can be connected to a Miniservers Link Interface according to the following diagram:
Connect the Extensions to a Miniserver by daisy-chaining the Link interfaces. If any of the Extensions are connected to a separate power supply, then all power supply's GND (negative) have to be interconnected. This connection is crucial for reliable data transmission.
The blue/white pair of a CAT5/6/7 cable is used to wire the Link throughout a building. This allows a maximum length of 500m/1640ft.
The Link interface is terminated at the last Extension using the 120 Ohm resistor that is included with the Miniserver.
After switching on the power supply, the Extensions first flash red, and after successful connection to the Miniserver they flash orange.
You can now proceed with pairing the Extensions.
Connecting Tree Devices↑
Up to 50 Tree Devices can be connected to the Tree Interface of a Miniserver, or each of the two branches of a Tree Extension. There must be no connection between different Tree branches.
The following diagram shows the wiring of several Tree devices connected to two different Branches of a Tree Extension.
The following wiring topologies are possible, at a maximum length of 500m/1640ft:
The Loxone Tree cable is used for wiring, it contains the Tree communication lines as well as the lines for the 24VDC power supply in the corresponding colors. For devices with higher power requirements such as Tree lighting products, the Tree cable also contains a pair of wires with 1.5mm² cross-section (AWG16) for power supply.
We recommend running one Tree cable from the panel per room and then branching off to the individual Tree devices in that room. This corresponds to a Tree topology.
Within the enclosure, panel wire is also used for wiring.
Devices that communicate with each other have to share a common GND. This is necessary if more than one power supply is used. (e.g. in a sub-panel, or if separate power supplies are used for lighting). For this all power supply's GND (negative) have to be interconnected. This connection is crucial for reliable data transmission.
The max. length of 500m applies to the communication lines of a Tree Branch, not to the line length of the 24V power supply. Especially Tree light fixtures have a higher power requirement that can lead to voltage drop on the 24V lines, and depending on the topology, the achievable line length can be significantly shorter.
For longer distances or higher loads, either use a separate power supply closer to the loads, or split the loads across multiple home runs. Alternatively, a separate line with a higher cross-section can be installed.
You can now proceed with pairing the Tree devices.

The installation must be carried out by a qualified technician in accordance with all applicable regulations.
The installation requires a suitable enclosure to ensure protection against contact, water and dust.
The device must not be used as part of safety-critical systems.
