KNX 762.1: KNX IP LineMaster 762.1 Secure | KNX 640 mA Power Supply with Router and IP Interface

The KNX IP LineMaster 762.1 secure combines the essential functions of a KNX bus line: KNX power supply with choke, KNX IP router, and KNX IP interface. In addition to the bus voltage, the power supply offers an auxiliary voltage.

The KNX IP router in the KNX IP LineMaster 762.1 secure allows forwarding of telegrams between different lines via a LAN (IP) as a fast backbone. Using the integrated KNX IP interface, the KNX line can be connected directly to a PC (e.g., via ETS). The device supports KNX Security, which can be enabled in ETS. As a secure router, the device allows coupling of unsecured communication on KNX TP to a secure IP backbone. Also for interface functionality (tunneling), KNX Security prevents unauthorized access. The IP address can be obtained via a DHCP server or, respectively, via manual configuration (ETS).

This device operates according to the KNXnet/IP specification using the core, device management, tunneling, and routing parts. The KNX IP LineMaster 762.1 secure has an extended filter table for main groups 0 to 31 and is capable of storing up to 150 telegrams.
