The Miniserver Compact serves as a central control unit for all kinds of automation tasks.
Interfaces for Link, Tree, Air and Tree Turbo are integrated for expansion with numerous devices.
This way, the Miniserver Compact also serves as an Audioserver.

The Miniserver is installed on a DIN rail in a suitable enclosure.
Connect the power supply, as well as needed inputs and outputs, or devices on the different interfaces.
The Link Interface (blue/white terminal) can also be switched to a Tree Interface in Loxone Config.
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 with twisted pairs is 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 cable length of max. 500m per tree branch refers purely to the data lines, not to the 24V power supply. For consumers with higher power such as tree lamps or tree dimmers, the achievable cable length is often significantly shorter due to the resulting voltage drop.
If the current flow on the GND line results in a voltage drop too high, this potential difference also affects the tree communication.
To solve this problem, split consumers of higher power over longer distances to several supply lines, or use a supply line with a higher cross-section, or a power supply close to the consumers.
For existing installations, doubling the cross-section of the GND line is often sufficient to eliminate the potential difference.
You can now proceed with pairing the Tree devices.
Connecting Tree Turbo Devices↑
Up to 10 Tree Turbo devices can be connected to the Tree Turbo interface of a Audioserver or Miniserver Compact.
The following wiring topologies are possible, at a maximum length of 150m/492ft:
The Loxone Tree Cable can be used for wiring. Use the green/white wire pair for Tree Turbo, and the 1.5mm² (AWG16) orange/white wire pair for the power supply.
For longer runs or multiple Tree Turbo devices with high power consumption, either install a power supply closer to them, or use multiple supply lines. A separate, larger cross-section supply line can also be used.
If separate power supplies are used, it is not necessary to connect all the GNDs.
|The Tree Turbo interface is based on a completely different technology than the well-known Tree interface. Therefore, the Tree and the Tree Turbo interface must not be connected! The Tree Turbo data lines should not be run together with other data or signal lines in the same cable.|
The Tree Turbo communication is IP based, therefore IP addresses for all Tree Turbo devices will appear on the network.
If Audioserver or Miniserver Compact are located in a 10.10.10.x network, then they must be set to DHCP and always be assigned the same address by the router, since the connected Tree Turbo devices also communicate in this address range, otherwise IP address conflicts can occur.
Tree Turbo devices will boot their operating system over the Tree Turbo Interface, after switching on the power supply. Thus the Audioserver or Miniserver Compact must also be ready for operation. After about one minute the Tree Turbo device is ready and will blink orange.
You can now proceed with pairing the Tree Turbo devices.
Pairing Air Devices↑
All Air devices have to be paired in Loxone Config via the pairing mode. In delivery state, pairing mode will be active after the power supply has been established.
On most Air devices, the status LED will indicate this by flashing red/green/orange. You can find the exact pairing mode signal in the documentation of the respective Air device.
On most battery powered Air devices the pairing mode is only active for 5 minutes to conserve energy. Briefly remove the battery and then reinsert it to reactivate pairing mode, if necessary.
If an Air device blinks only orange, then it was previously paired, but can no longer establish a connection. In this case, you have to activate the pairing mode manually. On most devices, this is done by pressing the pairing button or power cycling the device.
Searching and pairing
To search for Air devices, first click on an Air Interface in Loxone Config, and then activate Air Device Search
The window that opens will list all Air devices that are in pairing mode. This can take a few minutes:
If you select a device here, it will identify itself in different ways. Devices with a status LED will flash it, light fixtures pulse a white light, other devices such as the Loxone Touch emit an audible click. This allows you to assign and name the devices correctly.
Select the desired device, assign a name, room and installation location and add it to the programming using the Pair Device or + button.
The right window lists all the devices that are currently part of the program. You can display them by clicking the button Show my Air devices. You can also replace an existing device with a new device of the same type that was found in the search. This is useful when a device needs to be replaced or devices are added to a pre-configured program. Select the device to be added and the device to be replaced. By clicking on the button with the arrow pointing right, the old device is replaced with the new one in the program.
To apply the changes, save the program in the Miniserver.
Now the added devices are ready for use and the functions are available in the Periphery Tree in Loxone Config.
The Loxone App, under Settings, also supports searching for and pairing Air devices.
The Device Status serves as a central overview of the status of all devices in the programming, This enables a fast, but also detailed error diagnosis.
The Device Status can be opened via the menu bar:
If a device is offline, currently being updated or has not yet been paired, this is highlighted in color in the status column:
With a right click on the desired device, individual information can be retrieved and actions triggered. These available options are device-dependent.
