ELSNER 70149 70149 KNX CP IP, KNX TP to IP Router

The ELSNER 70149 product, known as KNX CP IP, is a specialized device for connecting the KNX TP bus and the IP/Ethernet network. This coupler is designed to filter telegrams in a topological and group-oriented manner, making it ideal for applications that require efficient data management.

Key Features

• KNX TP bus connection with the IP/Ethernet network, allowing KNX IP to be used as a fast backbone medium.
• Support for extended frames and telegrams up to 240 bytes in APDU length, especially useful for energy measurement and visualization applications.
• It works without external power, reducing installation complexity.
• For IP tunneling, four different parallel tunneling connections can be created, each with a separate address, with a quick assignment possible through the web interface.
• Sending IACK on sent messages configurable through ETS.

Supported Protocols

• KNXnet/IP
• ARP
• ICMP
