The IP Interface N148/22 is a DIN rail mounted device.
This device utilizes the KNXnet/IP standard and
enables communication connections to KNX/EIB lines
or systems via data networks using the Internet
Protocol (IP). PC’s or other data processing equipment
can exchange data with KNX/EIB devices through this
communication link.
The physical connection to the KNX/EIB bus 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 a KNX/EIB installation can be
remotely accessed even if there is no direct data
network connection between a PC and an IP Interface.
LAN modems are available on the market for standard
telephone, ISDN or DSL connections.
The IP Interface requires additional operating power for
its operation. The IP Interface N148/22 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 Interface 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)
-
Communication between buildings and facilities
-
