KNX IP LineMaster 760
Operating and installation manual
Application
The KNX LineMaster combines the essential functions of
a KNX bus line: Power supply with choke, IP Router and
IP Interface.
In addition to the bus voltage the power supply offers an
auxiliary voltage of 24 V. The IP Router in the LineMaster
allows forwarding of telegrams between different lines
through a LAN (IP) as a fast backbone. Using the em-
bedded IP Interface, the KNX line can be connected
directly to a PC (e.g. by ETS).
This device works according to the KNXnet/IP
speci-fication using the core, the device management, the
tunneling and the routing part. The router included in the
KNX LineMaster 760 has a filter table and is able to buff-
er up to 150 telegrams.
Coupler function (KNXnet/IP routing)
The KNX IP LineMaster 760 can operate as a line and/or
backbone coupler. In both cases, the LAN (IP) acts as a
backbone.

The physical address assigned to the KNX IP LineMaster
760 determines whether the device operates as a line or
backbone coupler. If the physical address is in the form of
x.y.0 (x, y: 1..15), the LineMaster operates as a line cou-
pler. If it is in the form of x.0.0 (x: 1..15), the LineMaster
acts as a backbone coupler.
Attention:
If the KNX IP LineMaster 760 is used as a backbone
coupler (x.0.0), there must be no KNX IP LineMaster in
the topology beneath it. For example, if a KNX IP Line-
Master has the physical address of 1.0.0, there must be
no KNX IP LineMaster with the address 1.1.0.
If the KNX IP LineMaster 760 is used as a line coupler
(x.y.0), there must be no KNX IP LineMaster in the topol-
ogy above it. For example, if a KNX IP LineMaster has
