Application

The KNX IP Router forwards telegrams between different lines via a rapid LAN (IP)

backbone. The KNX IP Router can also be used as an interface for accessing the bus via IP,

replacing an RS232 or USB interface. It has an external 12 V to 24 V power supply or can

alternatively be powered via Power-over-Ethernet (IEEE 802.3af).

The EIB/KNX IP Router has a filter table and is able to buffer up to 150 telegrams.

Note:

The Power over Ethernet supply is standardized acc. to Standard PoE (IEEE

802.3af) and integrated via RJ45. We can recommend a PoE Ethernet Switch from

Netgear, e.g. FS108P. The device disposes of 8 ports, four of which are equipped

with Power over Ethernet (IEEE802.3af, 48 VDC). The IP router for example, can

be connected to one of these four ports. As an alternative, power supply can be

provided by means of screw connecting terminals at the upper side using a

separate power supply unit (12-24V DC) or transformer (12-24V AC). Parallel

power must be avoided!

Operating and installation manual

Coupler function (KNXnet/IP routing)

The EIB/KNX IP Router can operate as a line and/or backbone coupler. In both cases, the

LAN (IP) acts as a backbone.

KNX IP Router as a backbone and line coupler

The physical address assigned to the EIB/KNX IP Router 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 router operates as a line coupler. If it is in the form of x.0.0 (x: 1..15), the

router acts as a backbone coupler.

Attention:

If the EIB/KNX IP Router is used as a backbone coupler (x.0.0), there must be no

KNX IP Router in the topology beneath it. For example, if a KNX IP Router has the

physical address of 1.0.0, there must be no KNX IP Router with the address 1.1.0.

Page 8

If the EIB/KNX IP Router is used as a line coupler (x.y.0), there must be no KNX

IP Router in the topology above it. For example, if a KNX IP Router has the

physical address of 1.1.0, there must be no KNX IP Router with the address 1.0.0.

The KNX IP Router has a filter table and thus contributes to reducing bus load. The filter

table is automatically generated by the ETS.

Because of the speed difference between the Ethernet (10 Mbit/s) and KNX/EIB (9.6 kbit/s),

a far greater number of telegrams can be transmitted on IP. If several consecutive

telegrams are transmitted on the same line, they must be buffered in the router to avoid

telegram loss. The EIB/KNX IP Router has a memory for 150 telegrams (from IP to

KNX/EIB).

Bus access function (KNXnet/IP Tunneling)

The EIB/KNX IP Router can be used as an interface to KNX/EIB. KNX/EIB 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 Router 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.

Page 9

Support of unparameterized interfaces:

An interface can be used with a physical address that does not fit into the line topology (e.g.

for putting the device into operation).

Parameters: disable, enable

Monitoring bus voltage failure:

If a KNX/EIB failure is detected, it is reported on the IP. Return 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

function, there must be a DHCP server in the LAN (many DSL

routers have an integrated DHCP server).

Manual: In this case, the IP address, the subnet and the gateway IP

address must be entered 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

adifferent multicast IP address is required, it must lie within the range of 239.0.0.0 to

239.255.255.255.

Page 10

IP adress:

This is the IP address of the EIB/KNX IP Router.

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 Router 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 EIB/KNX IP Router.

IP address of the PC: 192.168.1.30

Subnet of the PC: 255.255.255.0

The EIB/KNX IP Router 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 router 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 router: 192.168.1.31

Subnet of the IP router: 255.255.255.0
