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.

Fig. 3: KNX IP LineMaster as a backbone and line cou-
pler
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

KNX IP LineMaster 760
WEINZIERL ENGINEERING GmbH EN
2014-07-01 Page 2/6
the physical address of 1.1.0, there must be no KNX IP
LineMaster with the address 1.0.0.
The KNX IP LineMaster has a filter table and thus con-
tributes to reducing bus load. The filter table is automati-
cally generated by the ETS.
Because of the speed difference between the Ethernet
(10 Mbit/s) and KNX (9.6 kbit/s), a far greater number of
telegrams can be transmitted on IP. If several consecu-
tive telegrams are transmitted on the same line, they
must be buffered in the LineMaster to avoid telegram
loss. The KNX IP Linemaster 760 has a memory for 150
telegrams (from IP to KNX).
Bus access function (KNXnet/IP Tunneling)
The KNX IP Linemaster 760 can be used as an interface
to KNX. KNX can be accessed from any point in the LAN.
For this purpose, a second physical address must be
assigned as described in the ETS Connection Manager
section.
ETS database
The following parameters can be set on the ETS:
General:
Device name:
The KNX IP LineMaster 760 can be assigned a name of
your choice. The device name should be descriptive (e.g.
Line TF). It is used to search for and recognize a device.
Monitoring bus voltage failure:
If a KNX failure is detected, it is reported on the IP. Re-
turn of the bus voltage is also reported.
Parameters: disable, enable
IP address assignment:
Automatic
(DHCP): The IP address is automatically assigned
on the DHCP, i.e. additional settings are
not required. To be able to use this func-
tion, there must be a DHCP server in the
LAN (many DSL routers have an inte-
grated DHCP server).
Manual: In this case, the IP address, the subnet
and the gateway IP address must be en-
tered manually.
IP configuration:
IP Routing Multicast Address:
This address is used for routing telegrams on IP. The
multicast IP address 224.0.23.12 was reserved
(KNXnet/IP) at the IANA (Internet Assigned Numbers
Authority) for this purpose. If a different multicast IP ad-
dress is required, it must lie within the range of 239.0.0.0
to 239.255.255.255.
IP address:
This is the IP address of the KNX IP LineMaster 760.
IP subnet:
Enter the subnet mask here. The device uses the values
entered in this mask to determine whether there is a
communications partner in the local network. If there is no
partner in the local network, the device will not send the
telegrams directly to the partner but to the gateway that
routes the telegram.
IP gateway address:
Enter the IP address of the gateway here.
Note: If the KNX IP LineMaster will only used in the local
LAN, the entry of 0.0.0.0 can remain unchanged.
Example of assigning IP addresses:
A PC is to be used to access the KNX IP LineMaster 760.
IP address of the PC: 192.168.1.30
Subnet of the PC: 255.255.255.0
The KNX IP LineMaster 760 is located in the same local
LAN, i.e. it uses the same subnet. The subnet constrains
the IP addresses that can be assigned. In this example,
the IP address of the IP LineMaster must be
192.168.1.xx, where xx can be a number from 1 to 254
(with the exception of 30, which is already in use). It must
be ensured that no numbers are assigned twice.
IP address of the IP LineMaster: 192.168.1.31
Subnet of the IP LineMaster: 255.255.255.0

Routing (KNX -> IP)
Group telegrams (main group 0 to 13):
Block: No group telegrams of this main group
are routed to IP.
Route: All group telegrams of this main group
are routed to IP independent of the filter
table. This setting is for testing purposes
only.
Filter: The filter table is used to check whether
or not the received group telegram
should be routed to IP.
Group telegrams (main groups 14 and 15):
Block: No group telegrams of main groups 14
and 15 are routed to IP.
Route: All group telegrams of main groups 14
and 15 are routed to IP.
Group telegrams (main groups 16 to 31):
Block: No group telegrams of these main groups
are routed to IP.
Route: An additional page appears on which the
routing of main groups 16 to 31 can be
disabled or enabled in pairs.
Note:
The group addresses of main groups 16 to 31 are re-
served addresses that can be used for special applica-
tions (e.g. in Easy Mode). These group addresses are not
available in the ETS.
Physically addressed telegrams:
Block: No physically addressed telegrams are
routed to IP.
Route: All physically addressed telegrams are
routed to IP.
Filter: The physical address is used to check
whether the received physically ad-
dressed telegram should be routed to IP.
Broadcast telegrams:
Block: No received broadcast telegrams are
routed to IP.
Route: All received broadcast telegrams are
routed to IP.
Acknowledge (ACK) of group telegrams:
Always: An acknowledge is generated for every
received group telegram (from KNX).
Only if
routed: An acknowledge is only generated for
received group telegrams (from KNX) if
they are routed to IP.
Acknowledge (ACK) of physically addressed telegrams:
Always: An acknowledge is generated for every
received physically addressed telegram
(from KNX).
Only if
routed: An acknowledge is only generated for
received physically addressed group tel-
egrams (from KNX) if they are routed to
IP.
Answer with
NACK: Every received physically addressed
telegram (from KNX) is responded to with
NACK (not acknowledge). This means
that communication with physically ad-
dressed telegrams on the corresponding
KNX line is not possible. Group commu-
nication (group telegrams) is not affected.
This setting can be used to block at-
tempts at manipulation.
Attention:
The setting Answer with NACK disables parameterisation
with ETS via the subline (KNX).
To reenable parameterisation via the subline (KNX), the
device has to be set into delivery status.

ETS Connection Manager
The KNX IP LineMaster 760 can only act as an interface
to KNX when the IP-configuration is valid.
The following configuration steps are required:
Select the button ‘Settings’ on the tab ‘Communication’ in
the main window of ETS4. All available connections are
listed under ‘Discovered connections’. Select the desired
connection.
The KNX IP LineMaster 760 supports up to 5 simultane-
ous tunneling connections. Each connection uses its own
physical address. The address of the first tunneling con-
nection can be changed within the ‘Local Interface Set-
tings’.
Physical addresses of the additional tunneling connec-
tions can be assigned directly on the device.
This is done by pressing the programming key on the
device (2) longer than one second. After that, the Learn-
LED will start blinking, which indicates that the assign-
ment of the additional addresses was successful.
The additional addresses are assigned as follows:
Tunneling connection 2 receives the next higher address
than tunneling connection 1, tunneling connection 3 the
next higher address than tunneling connection 2 etc..
For example:
Device address: 1.1.0 (address within ETS topology)
Connection 1: 1.1.250 (address within local settings)
Connection 2: 1.1.251 (assigned by programming key)
Connection 3: 1.1.252 (assigned by programming key)
Connection 4: 1.1.253 (assigned by programming key)
Connection 5: 1.1.254 (assigned by programming key)
All addresses have to be unique and valid within the
LineMaster’s sub line. Note: be careful not to assign the
same address as the device address for a connection.
The device address can be changed within the topology
view of the ETS software.
For new devices (i.e. in the factory settings state), only
the additional individual address of the first connection is
active with the address 15.15.250. To support multiple
concurrent connections additional address assignment is
required.
