IP Router N 146/02
Description
The IP Router N 146/02 implements the KNXnet/IP
standard and connects KNX lines to data networks
using the Internet Protocol (IP). This device offers
concurrent access to the bus line from up to four
computers or other data processing equipment.
The physical connection to the KNX network is
established through a Bus Terminal block. For
connection to the data network (IP using 10Base-T),
the device contains an RJ-45 socket.
Using a LAN modem, a KNX installation can be
remotely accessed even if there is no direct network
connection between a computer and an IP Router
N 146/02. LAN modems are readily available for
standard telephone, ISDN, or DSL connections.
The IP Router N 146/02 requires additional operating
power from only one of the following sources:
• A Power over Ethernet (PoE) network connection
according to IEEE 802.3af.
• A second terminal block (white-yellow terminals)
connected to a Class 2 power supply AC/DC 24V.
• A Gamma Power Supply Unit N 125/21 (unchoked
power, 29 Vdc).
The IP Router N 146/02 creates a logical data
connection between KNX bus lines by transmitting
telegrams through a data network but keeps the lines
electrically separate. This allows each bus line to be
run independent of the others.
The IP Router N 146/02 can be used as a line coupler
or area coupler in existing or new KNX networks. The
device maintains a filter table that determines which
bus telegrams are transmitted or blocked, thus
reducing the bus load. The filter table is automatically
generated by ETS (Engineering Tool Software) during
configuration and start-up of the system.
The following features are integrated in the device:
• Fast communication between KNX lines, areas,
and systems (KNXnet/IP Routing)
• Filtering and routing of telegrams depending on
individual address or group address
• Simple configuration with ETS, local to the job site
or remote, leveraging the available wired or
wireless IP infrastructure (KNXnet/IP Tunneling)
• Status LEDs showing operation and KNX and IP
communication
• Simple connection to other devices or systems
connected to the same Internet Protocol (IP)
network.
