KNX IP LineMaster 762.1 secure

 KNX IP LineMaster 762.1 secure

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 through a LAN (IP) as a fast backbone. Using the embedded KNX IP interface, the KNX line can be connected directly to a PC (e.g. by ETS). The device supports KNX Security which can be enabled in ETS. As secure router the device allows coupling of not secured communication on KNX TP to a secured IP backbone. Also for the interface functionality (unneling) KNX security prevents from unauthorized access. The IP address can be obtained by a DHCP server or by manual configuration (ETS) respectively.

This device works according to the KNXnet/IP specification using the core, the device management, the tunneling and the routing part. The KNX IP LineMaster 762.1 secure has an extended filter table for main groupls 0 to 31 and is able to buffer up to 150 telegrams.

Power supply with choke

The power supply with high efficiency of the KNX IP LineMaster 762.1 secure provides a 30V bus voltage for the KNX system and an additional output with auxiliary voltage for supplying other devices. Special operating conditions such as short circuit, overvoltage, overload or overtemperature are logged and can be read off the display. The current current consumption is also displayed. A reset of the connected bus nodes is possible via the keypad.

KNX IP Router

The KNX IP LineMaster 762.1 secure integrated KNX IP router allows the transmission of telegrams to other lines via the LAN (IP) as a fast backbone (KNXnet/IP routing). The KNX IP LineMaster 762.1 secure thus also assumes the function of a KNX line coupler.

KNX IP Interface

The KNX IP LineMaster 762.1 secure can be used as an interface for bus access via IP. The KNX system can be configured and monitored from any PC in the LAN (KNXnet/IP tunnelling).
