Installation Diagram

Graphic or Wiring diagram of Loxone RS485 Extension installed. In the diagram you see the RS485 Extension installed to the right of the Miniserver Gen 2. Both are powered by a DIN rail 24VDC power supply. The Miniserver, the power supply and the RS485 Extension are installed on a DIN rail which is attached inside the panel. To the left of the Miniserver is a DIN rail mounted 24VDC power supply. The power supply has a 2-conductor wire connected to the Miniserver to provide 24VDC power. From the top of the Miniserver is also a line indicating its attachment to the LAN via a network switch which is located outside and on the top of the panel. The RS485 Extension is also getting a blue cable from the Miniserver which indicates a Loxone Link Communication.
