Operating Instructions
IP Central Unit

1. System information

This device is a product of the instabus EIB system and complies with
EIBA directives. Detailed technical knowledge obtained in instabus
training courses is a prerequisite to proper understanding. The
functionality of this device depends on the software. Detailed information
on loadable software and attainable functionality as well as the software
itself can be obtained from the manufacturer’s product database.
Planning, installation and commissioning of the unit is done by means of
EIBA-certified software. The latest version of the product database and of
the technical descriptions are always available in the Internet under
www.jung.de

2. Safety warnings

Attention
Electrical equipment must be installed and fitted by qualified

electricians only and in strict observance of the relevant accident
prevention regulations. Failure to observe any of the installation
instructions may cause fire and other hazards

Important: The present installation instructions are to give a first

overview of the use and information on the connection of the IP central
unit. A detailed description of the product and configuration of the
necessary devices can be found in the respective EIB product
documentation.

Stand: Aug-07 325 491 03

3. Function

The IP central unit is the interface between the Ethernet LAN (Local Area
Network) and the instabus EIB, and in future also the e2i system. With an

Ethernet connection, the user has access from the local PC of his LAN or
also via the Internet to his instabus EIB or to his e2i system. The Internet
connection can be established via DSL, LAN (RJ45-port) or also with a
V90 modem / ISDN-adapter (RS232 port). The IP central unit acts as a
server and can be comfortably operated as a central control, reporting

and checking unit with the web browser of a PCs (Microsoft
Explorer from V 5.5 onwards) or other suitable LAN devices as, for
instance, a PDA.

4. Characteristics

User-controlled commissioning and configuration assistant, system clock
functions, central year timer switch with astro function and day profiles,
presence simulation, logic functions, event reporting function via e-mail,
integrated e-mail address book, central functions, lightscenes, scenes for
HVAC and alarm system applications, etc.

4.1. Directory server

Data exchange with the IP central unit via the Internet requires the use of
a directory server. A directory server is a server which can be reached via
Internet and which is the interface between a PC and the IP central unit.
When accessed from the web browser, a web page of the directory
server opening up a portal is first called up. The directory server checks
the connection or establishes the connection with the IP central unit.
When the connection has been established, access via the open portal to
the IP central unit is possible after verification of the access data.

5. Modes of operation

Depending on the existing system equipment, the IP central unit can be
operated in different modes.

• operation in an LAN

• operation in an LAN via a dedicated phone line to the Internet

• operation in an LAN with dial-in connection to the Internet and

triggering via modem (analog or ISDN)

• operation in an LAN with triggering or a-b port behind a telephone
system

• operation in a telephone system with dial-in to the Internet via
modem (analog or ISDN)

The Connection required in each case is shown in the pictures below.

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.
