The bus/line coupler function allows the creation of different types of gateways. Several bus systems can be connected to each other in different ways via the current device.
Examples of areas of application are:
- ekey KNX interface – enables the ekey bus system to be connected to a KNX line
- Loxone Miniserver (v1) – enables the connection of the Loxone Link bus system with a KNX line
- Loxone Tree-Extension / Miniserver (v2) – enables the connection of the Loxone Link bus system with Loxone Tree bus line(s)
- Gira DCS IP gateway – enables the connection of the “indoor” bus system with the “video/outdoor” bus system
- Timberwolf Server – enables the connection of a KNX line with several 1-wire buses
- DMX-Gateways
For this configuration, incoming and outgoing bus systems are divided. Both fulfil the same function (to connect the current bus system of the device with others), the only difference here is in the graphic representation (see below)
If you select the “Plus” or “Edit” symbol for incoming or outgoing bus systems, all other bus systems will be displayed in a selection window. You can make multiple selections in this window.
The following can be used as a rough guideline
- Use incoming connections for bus systems that appear further ahead in the diagram
- Use outgoing connections for bus systems that appear further back in the diagram.
Incoming bus connections
This is an example of the graphic representation of incoming connections (using the ekey KNX gateway as an example).
- The DIN-rail device is connected to its assigned main bus (ekey bus)
- The incoming connection of the linked bus system is shown above the device (KNX bus)
Outgoing bus connections
This is an example of the graphic representation of outgoing connections (using the Gira DCS IP gateway as an example)
- The DIN-rail device is connected to its assigned main bus (“indoor” bus)
- The outgoing connection of the linked bus system is shown below the device (“outdoor/video” bus)
- In this example, a 24V supply was also selected.
