Overview of the different indications of the KNX LED
❹
:
The IP LED
❻
lights up when an Ethernet link is active. This
LED is green if the device has valid IP settings (IP address, Sub
net and Gateway). With invalid or nonexistent IP settings the
LED is red. This is also the case if e.g. the device has not yet
received the IP settings by a DHCP server.
This LED indicates IP telegram traffic by flickering.

The Mode LED
❺
can visualize the status of each BAOS and
KNXnet/IP tunneling connection.
With the button Conn BAOS
❼
you can chose each single
BAOS connection. Pressing the button Conn BAOS
❼
counts
the connection numbers up. The actually selected connection
number is indicated by flashing (1x…10x) of the Mode LED
❺
.
An available BAOS connection is indicated by a green LED and
a used BAOS connection is indicated by an orange LED.
With the button Conn Tunn
❽
you can chose each single
KNXnet/IP Tunneling connection. Pressing the button Conn
Tunn
❽
counts the connection numbers up. The actually se-
lected connection number is indicated by flashing (1x…5x) of the
Mode LED
❺
. An available KNXnet/IP Tunneling connection is
indicated by a green LED and a used tunneling connection is
indicated by an orange LED.
Via the Escape function (Esc) this indication can be ended by
simultaneously pressing the buttons Conn BAOS / Conn Tunn

.
If neither programming mode nor manual mode are active the
LED
❺
can visualize configuration errors.

Factory default settings
The following configuration is set by factory default:
Individual device address:
15.15.255
Number of configured KNXnet/IP tunneling con.:
1
Individual address of tunneling con.:
15.15.250
IP address assignment:
DHCP
Reset to factory device settings
It is possible to reset the device to its factory settings:
Disconnect the KNX Bus connector
❶
from device
Press the KNX programming button
❸
and keep it
pressed down
Reconnect the KNX Bus connector
❶
of device
Keep the KNX programming button
❸
pressed for at
least another 6 seconds
A short flashing of all LEDs (
❷❹❺❻
) visualizes the
successful reset of the device to factory default settings.
Interface settings with ETS
Within the ETS KNX interfaces can be selected and set up via
the ETS menu "Bus Interfaces".
The ETS can access configured KNX IP BAOS even without a
database entry. If the setup of the KNX IP BAOS does not com-
ply with the conditions of the KNX installation it must be config-
ured via an ETS project. See the ETS database section for more
information.
As factory default the assignment of the IP address is set to
“automatically via DHCP” and thus no further settings are neces-
sary. To use this feature a DHCP server on the LAN must exist
(e.g. many DSL routers have an integrated DHCP server).
After connecting the KNX IP BAOS to the LAN and the KNX bus,
it should automatically appear in the ETS within the menu "Bus"
under "Discovered interfaces".
By clicking on the discovered interface it is selected as the cur-
rent interface. On the right side of the ETS window all specific
information and options of the connection appear.
The indicated device name and the "Host Individual Address"
(individual address of the device) can be changed within your
ETS project then.
Like all programmable KNX devices the KNX IP BAOS 774 has
an individual address which can be used to access the device.
This is used, for example, of the ETS when downloading to the
KNX IP BAOS via the bus.
For the interface function the device contains additional individu-
al addresses that can be set in the ETS (ETS 4.2 or higher).
When a client (e.g. ETS) sends via the KNX IP BAOS telegrams
to the bus, they contain a sender address as one from the addi-
tional addresses. Each address is associated with a connection.
Thus response telegrams can be clearly transmitted to the re-
spective client.
The additional individual addresses must be selected from the
address range of the bus line in which the KNX IP BAOS is
installed and may not be used by another device.
