KNX
IP Central Unit
Ref.-no.: IPZ 1000 REG
Designation and function of the connecting ports
(1) bus connection terminal for EIB connection
(2) screw terminals for polarity-independent 24 V DC connection, e.g.
from the unchoked output of the EIB power supply unit
(3), (4)
e2i
system contacts for future
e2i
applications (presently not
supported)
(5) RJ45 socket for LAN connection
(6) 9-pole SUB-D plug for V90 modem or ISDN adapter
(7) screw terminals for a-b trigger input
(8) 3 LEDs:
power (green) => lit up after initialization and presence of 24 V supply
voltage
online (yellow) => signals active connection via the RS232 interface
link (yellow) => lit up when connection to LAN (Ethernet connection
point, ECP) is established, flickers during data transmission via LAN
port
5.1. Operation in LAN
Access to the IP central unit is via a local Ethernet (LAN) from a local PC.
Operation in LAN with dedicated phone line
A local Ethernet (LAN) establishes – e.g. by means of a router – a
permanent connection with the Internet. This is useful in the event of a
flat-rate tariff. With „keep-alive“ telegrams, the IP central unit ensures that
the router does not disconnect the link. After a forced disconnection by
the service provider, the directory server is informed about the new IP
address when the link is reestablished. Access from outside is by means
of an external PC and its brower interface after passwort entry via a safe
Internet connection. After successful log-in, the web page of the IP
central unit appears. The EIB system can then be monitored and
operated directly.
