The Info LED simplifies the
commissioning:
Switching on:
Info LED is on continuously
Boot operation finished:
Info LED is blinking
Shortly afterward:
The RS-232 interface is initialized :
Short impulses can be observed at
the Info LED

Commissioning of the RS-232
interface
Figure 2 shows the basic structure of a KNX™ network which is connected to the Enertex
®
EibPC.
To integrate the Enertex
®
EibPC into the KNX™ system, proceed as follows
1.
Connect the Enertex
®
EibPC to a 24V - 30V DC power supply. This can be accomplished
either by a separate power supply or by the KNX™ bus. If you want to connect the
Enertex
®
EibPC to the KNX™ bus, you need to insert an appropriate choke between the
bus line and the Enertex
®
EibPC.
2.
Connect the LAN port (2) of the Enertex
®
EibPC to the LAN.
3.
Connect the RS-232 interface (3) of the Enertex
®
EibPC to an KNX™ RS-232 interface
( FT 1.2 protocol only) with an extension cable (“Male“ to “Female“).
4.
Restart the Enertex
®
EibPC (via EibStudio or simply interrupt the Enertex
®
EibPC's power
supply).
Please note:
The external safety extra-low voltage is connected through the device to the ground potential of the
LAN. Thus, there is no longer an isolation to the ground potential when the LAN shielding is
grounded. To establish an isolation, it is recommended to use an external extra-low voltage power
supply only for the Enertex
®
EibPC.
When the EibPC is starting, the RS-232 interface must be already connected to the switched-on bus.
To ensure this, proceed as follows:
1.
Wiring as described above.
2.
Connect the interface to the switched-on bus.
3.
Restart the Enertex
®
EibPC (by the EibStudio or simply interrupt the Enertex
®
EibPC's
power supply).
4.
If you are using an FT1.2 RS-232 interface:
When the Enertex
®
EibPC is starting, the
RS-232 interface must be already connected to the switched-on bus.
So do not
first switch on the Enertex
®
EibPC and then establish the RS-232 connection.
The RS232 interface may be switched on simultaneously with the Enertex
®
EibPC, but not
after booting the Enertex
®
EibPC.
5.
If you are using an IP interface:
Because an IP interface could sometimes be in a locked
state, it should be reset once.
The interface is accessed and activated only after the
transfer and the subsequent start of an application program.
The Enertex
®
EibPC uses the
so-called tunneling mode of the IP interface. Thereby, it is exclusively occupied, i.e. you
can not address the interface in this mode from the ETS. Nevertheless, in order to allow a
short-term access to the interface you can separate the interface via the menu item
C
ONNECT
and D
ISCONNECT
from Enertex
®
EibPC and reconnect with it, respectively.
Now the installation of the Enertex
®
EibPC to your KNX
TM
-system is finished.
