Technical specifications

Type Description

N 140/03

N140/13

N 140/03, N140/13 line/backbone couplers

• For data exchange between two KNX bus lines with telegrams

of up to 64 byte

• For use as line coupler for connecting a line to the main line or

as backbone coupler for connecting a main line to the

backbone line or as repeater for connecting two segments of

the same line, with electrical isolation of the two bus lines

• Loadable filter table for control of the data exchange between

the two bus lines

• Additional loadable filter table for telegrams with LTE addressing

• Detection of a communication fault on the lower-level line and

signaling to the higher-level line

• 3 LEDs for display of availability and receipt of a telegram per line

• Power supply from the main line

• Modular installation devices for mounting on

TH35 EN 60715 mounting rail

N 140/03 line/backbone couplers

• With bus connection to the line via contact system for

data rail and to the main line via bus terminal

• Width: 1 MW (1 MW = 18 mm)

N 140/13 line/backbone couplers

• Bus connection to the line and to the main line via

bus terminal

• Width: 2 MW (1 MW = 18 mm)

N 146 N 146 IP routers

2)3)

• For data exchange between two KNX bus lines with telegrams

of up to 64 byte

• For interconnection of bus lines or bus areas over a fast data

network (Ethernet 10BaseT) with Internet protocol (IP)

• Can be used as line, area or network gateway (worlds gateway)

• Loadable filter table for control of the data exchange between

the two bus lines

• Additional loadable filter table for telegrams with LTE addressing

• Detection of a communication fault on the lower-level line and

signaling to the higher-level line

• For communication between KNX devices and PCs and in

conjunction with a LAN modem for remote access to an

KNX installation

• Uses the KNXnet/IP protocol

• Assignment of the network parameters by the installation

engineer using ETS or automatically by a DHCP service in

the network

• 5 LEDs for indicating that the device is ready-to-run,

KNX communication, IP communication

• Electronics powered over an external power supply unit for

12 ... 30 V

• Plug-in terminal block for the connection of an external

power supply unit

• Integrated bus coupling units

• Bus connection via bus terminal

• Ethernet connection over RJ45 socket

• Modular installation devices for mounting on

TH35 EN 60715 mounting rail

• Width: 2 MW (1 MW = 18 mm)

As far as the hardware is concerned, there is no difference between line coupler, backbone coupler or repeater. They therefore have the same order number.

The function of the device is set during commissioning with the ETS.

During configuration of the IP interface, the installation engineer should carry out all the necessary settings; the network parameters can be assigned either

by the installation engineer over the ETS or automatically by a DHCP service in the network.

The N 146 IP router can only function smoothly as a line coupler (KNXnet/IP routing) if it is equipped with network components that support IP multicasting.

In particular, network/LAN routers must support or be configured so that they can relay IP multicast datagrams. The IP multicast address 224.0.23.12 is

reserved internationally for KNXnet/IP routing.

For selection and ordering data, see page 14/13.
