Connects the KNX bus to the Ethernet network and encrypts communication on the IP backbone. The device uses the KNXnet/IP Secure protocol for communication (routing and tunneling). It can be used as a fast line and area coupler. The complete filter table for main groups 0 to 31 is supported. KNX devices can be programmed via the LAN using the ETS. 5 Secure Tunneling Servers are available for this and additional clients. The IP address can be fixed or received from a DHCP server. Power supply via 12...30 V DC or PoE (IEEE 802.3af Class 1). KNX standard communication (multicast) can be switched off. In this case, up to 10 IPR/S 3.5.11 can communicate via unicast communication.
