KNX IP Router 752 secure

The KNX IP Router 752 secure enables the secure forwarding (routing) of telegrams between different lines over a LAN (IP, Ethernet) as a fast backbone. As a secure router, the device enables the connection of unsecured communications on a KNX TP line with a secure IP backbone. The KNX IP Router 752 secure has an extended filter table for main group 0..31 and can cache up to 150 telegrams.

The device also serves as a secure interface between IP (Ethernet) and KNX and can be used as a programming interface for the ETS®. As a KNX Secure Interface (tunneling), the device prevents unauthorized access to the system. The connection between PC and interface is encrypted.

With the KNX IP Router 752 secure, the KNX bus can be accessed from any point in the LAN. Encryption also enables secure programming over the Internet. The security option can be activated or deactivated in the ETS.
