Connecting KNX devices
1. Connect an Ethernet cable from the building's network jack to the port on the front of the KNX
gateway (Figure 13).
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.
2. Connect an Ethernet cable from the building's network jack to the RJ-45, 8-pin Ethernet port on
the network engine.
