Product and Applications Description
The IP Router N146/02is a DIN rail mounted device.
The device implements the KNXnet/IP standard and
connects KNX/EIB lines via data networks using the
Internet Protocol (IP). Also this device offers concurrent
access to the bus line from any PC or other data
processing equipment.
The physical connection to the KNX/EIB is established
via a bus connector terminal block. For connection to the
data network (IP via 10BaseT) the device contains an
RJ45 socket.
By using a LAN modem an KNX/EIB installation can be
remotely accessed even if there is no direct data
network connection between a PC and an IP Router.
LAN modems are available on the market for standard
telephone, ISDN or DSL connections.
The IP Router requires additional operating power for its
operation. The IP Router N146/02 can source this
operating power via the network connection from “Power
over Ethernet” according to IEEE 802.3af. Alternatively,
the operating power can be provided via a second
terminal block (white-yellow terminals) by a safety extra
low voltage (SELV) power supply AC/DC 24 V or by a
bus power supply (unchoked power, DC 29V). When a
SELV power supply is connected the operating power is
sourced from it.
The IP Router has these characteristics:
·Simple connection to hierarchically superimposed
systems via Internet Protocol (IP)
·Direct access to the KNX/EIB installation from any
access point to the IP network (KNXnet/IP Tunneling)
·Fast communication between KNX/EIB lines, areas
and systems (KNXnet/IP Routing)
·Communication between buildings and facilities
·Filtering and routing of telegrams depending on
- individual address
- group address
·LED display of
- operation
- KNX/EIB communication
- IP communication
·Simple configuration with standard ETS
·Easy connection to SCADA and Facility Management
systems (see: Supported Software)
IP Router as line / area coupler (KNXnet/IP Routing)
Using the existing data network for communication
between bus lines in non-residential buildings is a logical
step. The advantages are: fast communication between
KNX/EIB lines, extension of an KNX/EIB system beyond
one building by using LAN and WAN connections, direct
transmission of KNX/EIB data to any network user,
KNX/EIB remote configuration from any network access
point.
The IP Router logically connects KNX/EIB bus lines by
transmitting KNX/EIB telegrams between them via a
data network but separates them galvanically. This
allows to run each bus line independently from other bus
lines.
The IP Router can be used as line coupler or area
coupler in existing EIB networks as well as in new
KNX/EIB networks. The IP Router holds a filter table
determining, which bus telegrams are transmitted or
blocked from or to the bus line thus reducing the bus
load. The filter table is automatically generated by the
ETS (EIB Tool Software) during configuration and start-
up of the system.
The physical address of the IP Router assigned by ETS
automatically determines the IP Router function as a line
coupler or area coupler. The definition follows these
assignments:
Coupler function Line
Area coupler Main line 1- 15
Line coupler Line 1- 15

Note
When assigning the physical address take care that IP
Router and line couplers receive the topologically correct
physical address (Fig. 1, IP Router as area coupler and
line coupler).
Adhere to these rules:
Rule 1:
In general an IP Router is used as a line coupler or an
area coupler. The physical address has the format x.y.0,
with x=1…15, y=1…15.
Rule 2:
If an IP Router is applied as an area coupler with the
physical address x.0.0 then no other IP Router with the
line coupler address x.y.0 (y=1…15) shall be placed
topologically „below“ this IP Router (Fig. 2, IP Router
N 146 as area coupler).
Rule 3:
If anIP Router is applied as a line coupler (e.g. with
physical address 1.2.0)then no other IP Router shall be
used with a superior area coupler address (e.g. 1.0.0) in
this installation (Fig. 3, IP Router N 146 as line coupler).

Note
Smooth operation of the IP Router as line coupler or
back-bone coupler using KNXnet/IP Routing requires
LAN network components that support IP multicasting.
In particular, network / LAN routers must be configurable
respectively configured to forward IP multicast
datagrams.
The IP multicast address 224.0.23.12 was specifically
reserved for KNXnet/IP internationally for this purpose.
IP Router as interface to the bus (KNXnet/IP Tunneling)
A direct connection between a networked PC and the
bus can be established via a data network and the IP
Router. This allows for accessing the bus from any
access point in the data network.
The IP Router N146/02 provides up to four KNXnet/IP
Tunneling connections, allowing for e.g. simultaneous
configuration with ETS3 and operation of a visualization.

P.O.Box 10 09 53, D-93009 Regensburg Subject to change without prior notice 2.11.1.13/3
Note
For stable communication via KNXnet/IP Tunneling the
IP Router must use a separate individual address for
each KNXnet/IP Tunneling connection. These additional
individual addresses must be different from the individual
address of the device and must not be used by any other
bus device. In ETS these individual addresses should be
reserved by proxy devices.
ObjectServer interface to thebus
A direct connection between a networked PC and the
bus can also be established via a data network and the
IP Router N146/02 using ObjectServer. ObjectServer
compared with KNXnet/IP Tunneling provides the
advantage that the communication can be maintained
even over network connections with a transmission time
for the datagrams of over one second (e.g. satellite
connections).
Assignment of additional individual addresses
Additional individual addresses are either assigned with
ETS or alternatively without a tool automatically by the
device itself.
The automatic address assignment for KNXnet/IP
Tunneling and ObjectServer is started when the learning
button is pressed during normal operation for more than
5 seconds but less than 10 seconds. The programming
LED flashes during the address assignment process.
The device checks which individual addresses are
already used by other bus devices connected to the bus
line. These addresses are not used for the address
assignment.
By adding additional bus devices at a later time one or
more of the additional individual addresses could be
assigned twice. When during normal operation the
learning button is pressed for more than 10 seconds all
additional individual addresses in the IP Router N146/02
are reset to the default value (15.15.255) and the
programming LED is turned off.
IP address assignment
The IP address of the IP Router N146/02 is assigned
manually using ETS, automatically by a DHCP server in
the IP network, or by the device itself (AutoIP).
Assignment of the IP address by a DHCP server allows
for changes of the device IP address without using ETS.
Configuration of the DHCP server may require the MAC
address, which is printed on the device. If a DHCP
server is not available the device assigns itself an IP
address (AutoIP).
Please consult your network administrator regarding
configuration of the parameters device IP address,
subnet mask, and DHCP.
Default factory settings
By default the KNXnet/IP Routing function is active.
When two KNXnet/IP routers are connected with each
other via a cross-over cable or via a network hub, bus
telegrams are routed by the KNXnet/IP Router without
any configuration.
The IP Router ships with these default factory settings:
·Physical address of theIP Router:
15.15.0 (= FF00 hex)
·Filter group telegrams
·All bus telegrams are repeated in case of
transmission errors
·The IP Router acknowledges routed telegrams only
·Support for devices with mis-matching physical
address
·Route broadcast telegrams
·Monitor the bus line
·IP address assignment via DHCP
Behavior on bus voltage loss / recovery on the bus line
When the IP Router detects a loss of bus voltage on the
bus line, this error is saved and annunciated via
KNXnet/IP. When theIP Router detects recovery of bus
voltage on the bus line, the error flag is deleted and the
resumption of bus voltage is annunciated via KNXnet/IP.
Application programs
The IP Router can be configured with ETS2 v12 or
higher.
It requires the application program "IP Router 001002".

includes download of device configuration via the bus
and the group monitor function of ETS3.
Note
The KNX Association has decided that IP routers shall
not implement support for busmonitoring.
The ETS3 driver currently does not support local
download.
Note
After installing the ETS3 driver and selecting the
IP Interface or the IP Router as communication interface
a windows message may pop up announcing that a
