Operation and installation manual
KNX IP LineMaster
Ref. 9018249B
KNX Power supply with integrated KNX IP Router and diagnosis functions
KNX IP LineMaster
Application
The KNX LineMaster combines the essential functions of a KNX
bus line: Power supply with choke, KNX IP Router and KNX IP
Interface with a small footprint of only 6 units (108 mm).
The KNX IP Router in the KNX IP LineMaster allows forwarding
of telegrams between different lines through a LAN (IP) as a fast
backbone. In addition this device is suited to connect a PC to the
KNX network e.g. for ETS® programming.
The IP address can be obtained by a DHCP server, by manual
configuration via the device menue or by downloading a config-
ured ETS application. 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 has a filter table (8 kByte) and is able to
buffer up to 150 telegrams.
An easy to read OLED display on the front panel enables the
user to display the operating parameters locally on the device.
Coupler function (KNXnet/IP Routing)
The KNX IP LineMaster operates as a line or backbone coupler.
In both cases, the LAN (IP) is used as a backbone.
The following table shows the application possibilities of the KNX
IP LineMaster compared to the classic topology:

KNX IP LineMaster as line coupler
The individual address assigned to the KNX IP LineMaster de-
termines whether the device operates as a line or area coupler. If
the individual address is in the form of x.y.0 (x, y: 1..15), the KNX
IP LineMaster operates as a line coupler. If it is in the form of
x.0.0 (x: 1..15), the KNX IP LineMaster acts as a backbone
coupler.
KNX IP LineMaster as area coupler
If the KNX IP LineMaster is used as an area coupler
(x.0.0), there must not be a KNX IP Router in the topolo-
gy beneath it. For example, if a KNX IP Router has the
individual address 1.0.0, there must be no KNX IP Rout-
er with the address 1.1.0.
If the KNX IP LineMaster is used as a line coupler
(x.y.0), there must not be a KNX IP Router in the topolo-
gy above it. For example, if a KNX IP Router has the in-
dividual address 1.1.0, there must be no KNX IP Router
with the address 1.0.0.
