The SNE connects to a KNX network device by using the KNX/IP interface router. After installation and wiring are complete, refer to the Network Engine and Server Commissioning for KNX Vendor Integration Application Note (LIT-12013148) for additional information.
  1. Connect an Ethernet cable to the port on the front of the KNX gateway as shown in Figure 1.
    Note: Depending on the size of your network, you can use either a KNX Interface or Router as a gateway. The Interface connects the network engine to a single KNX line, while the Router acts as both an Interface and a Line Coupler over Ethernet to connect the network engine to the network, not to a single device.

    Callout Description
    1 To power supply
    2 To KNX devices
    3 To Ethernet network
  2. For a single KNX line, wire from the red and black terminals on the gateway to the devices. For multiple KNX lines, wire from the red and black terminals on each gateway to the devices on the same KNX line.
    Note: Specific cabling can vary depending on the topology and site. See Wiring considerations and guidelines for network integrations.
  3. Wire each KNX gateway to its own dedicated power supply on the KNX line. Do not supply power to the gateway until after you turn on the network engine.
  4. Go to Connecting the power source.
