Interra KNX IP Interface serves as a universal interface for devices at the IP layer to access the KNX bus line. The KNX bus line can be accessed from any point on the LAN. It can be used as a programming interface for ETS® from ETS 3.0f onwards. However, a maximum of 5 simultaneous connections are possible for access via KNXnet/IP Tunneling. Additionally, the IP address can be obtained via a DHCP server or manual configuration (ETS), respectively. The energy required to operate the device is provided via KNX line.
