The KNX IP Secure Router (2 SU) is the central component of KNX systems in order to make sure, that IP communication scales up to the maximum possible security. The device authenticates and encrypts KNX and IP telegrams. An potential IP attack, e.g. from outside (Internet) or inside (Intranet) does not see the real contents of KNX-IP telegrams. Telegram rate limitation, max. telegram lengths up to 248 bytes and bus performance up to 49 telegrams per second optimize the use of logics and visualizations. The OLED display simplifies the diagnosis. The topology error detection and the temporary filter deactivation facilitate commissioning diagnostics
