CLEARANCE ITEM - INTERFACE IP ROUTER, N146/02
The IP Router N146/02 is 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.
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 ÒPower over EthernetÓ
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 N146/02 logically connects KNX/EIB bus lines by
transmitting EIB telegrams between them via a data network
but separates them galvanically. This allows running each bus
line independently from other bus lines.
The N146/02 can be used as line coupler or area coupler in
existing KNX/EIB networks as well as in new KNX EIB
networks. The N146/02 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 (Engineering Tool Software) during configuration
and start-up of the system.
