Parameter
The device has 1000 bytes available for user defined parameters
which can be accessed via the BAOS protocol.
Parameter Byte
For each of the parameter bytes a value between 0 and 255 can
be entered.
Programming
The KNX IP BAOS 774 can be programmed in different ways by
the ETS:
Via KNX Bus
The device only needs to be connected to the KNX bus. The
ETS requires an additional interface (for example, USB) to have
access to the bus. Via this way both the individual address and
the entire application including IP configuration can be pro-
grammed. Programming via the bus is recommended if no IP
connection can be established.
Via KNXnet/IP Tunneling
No additional interface is required. Programming via KNXnet/IP
Tunneling is possible if the device already has a valid IP configu-
ration (e.g. via DHCP). In this case the device is displayed in the
interface configuration of the ETS and must be selected. The
download is executed via the ETS project as with many other
devices.
Via direct IP connection
While KNXnet/IP Tunneling and is limited to the speed of KNX
TP the device can be loaded via a direct IP connection at high
speed. The direct IP connection is possible if the device already
has a valid IP configuration as well as an individual address. To
do this select "Use direct IP connection if available" in the ETS
menu "Bus
– Connections - Options". The download is then
directly performed in the device and is not visible in the ETS
group monitor.
Due to the significantly shorter transmission times it is
recommended to perform downloads via IP.
WARNING
The device must be mounted and commis-
sioned by an authorized electrician.
The prevailing safety rules must be heeded.
The device must not be opened.
For planning and construction of electric in-
stallations, the relevant guidelines, regulations
and standards of the respective country are to
be considered.
