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 configured 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 determines 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 topology beneath it. For example, if a KNX IP Router has the
individual address 1.0.0, there must be no KNX IP Router 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 topology above it. For example, if a KNX IP Router has the individual address 1.1.0, there must be no KNX IP Router
with the address 1.0.0.

KNX IP LineMaster as area and line coupler
The KNX IP LineMaster has a filter table and thus contributes to
reducing the bus load. The filter table (8kB) supports the extended group address range and is automatically generated by the
ETS.
Because of the speed difference between the Ethernet (100
Mbit/s) and KNX TP (9.6 kbit/s), a far greater number of telegrams can be transmitted on IP. If several consecutive telegrams
are transmitted for the same line, they must be buffered in the
router to avoid telegram loss. The KNX IP LineMaster has a
memory for 150 telegrams (from IP to KNX).
Bus access function (KNXnet/IP Tunneling)
The KNX IP LineMaster can be used as an interface to KNX. The
KNX bus can be accessed from any point in the LAN. The device
supports up to 6 simultaneous Tunneling connections. For each
connection an additional individual address must be assigned.
This is described in the following sections.
Installation and Connection
The KNX IP LineMaster is designed for installation on DIN rail
with a width of 6 units (108 mm). It features the following controls
(❼❽❾❿) and displays (❺
❻):

The settings of the device can be accessed via
1. Local display on the device (partly)
2. ETS (Version 4.2 or higher)
The KNX Programming Mode is activated/deactivated by
simultaneously pressing the buttons ❽❿ – when activated the programming LED
❻ lights up.
Programming and status LED ❻
The red LED on the front panel is used to display the KNX programming mode and errors. The LED can have the following
states:
LED off: The programming mode is not active and
there is no error (normal operating mode).
LED lights up: The programming mode is active,
any errors are not visualized/notified by the LED,
but can be read on the display.
LED flashes quickly: The programming mode is
not active. The rapid flashing indicates one of the
following faults:
o Overload (sum of the current of auxiliary
and Bus power)
o The device is not loaded correctly, for
example, a cancelled download.
