KNX IP Interface 732 secure

The KNX IP Interface 732 secure serves as a secure interface between a LAN (IP, Ethernet) and KNX and can be used as a programming interface for ETS®. As a secure KNX interface (tunneling), the device prevents unauthorized access to the system. The connection between PC and interface is encrypted. The security option can be activated or deactivated in ETS. With the KNX IP Interface 732 secure, the KNX bus can be accessed from any point in the LAN. Encryption also allows secure programming via the Internet. The device is characterized by a compact design with a width of only 1 module (18 mm) and is powered by the KNX bus. The buttons and LEDs on the device allow local diagnosis of the current operating status and any communication errors.
