CB NCI – KNXnet / IP Programming Interface

CB NCI is the interface that connects the KNX installation bus with the IP network. The CB NCI uses the standardised KNX protocol KNXnet/IP.


Pluggable terminal blocks to connect to the external voltage source AC/DC 24 V, bus connection via bus terminal, Ethernet connection via RJ45 plug, 2HP modular device.

Programming interface

KNX installations can be accessed remotely in connection with a LAN-modem or DSL Router. CB-NCI supports 5 tunnel connections which can be used, for example, as ETS programming connections. Network parameters such as multicast address, IP address, subnet mask and standard gateway are programmed with the ETS.

Visualisation interface

CB-NCI also offers an object server connection which can be used for visualisation systems such as ComBridge Studio Evolution. Both connection types – tunnel and object server connection – can be used in parallel.
