The RXB39.1 room controller communicates with other devices via the following
interfaces:
PPS2 interface (proprietary) for the exchange of data with the room units
KNX bus (terminals CE+ and CE-) for communication with:
PX/KNX interface (to Desigo Insight)
Interface OCI700 (to Synco)
Other RXB controllers
Other KNX devices (e.g. field devices)
To facilitate commissioning, the tools ETS / ACS can be connected at three diffe-
rent points (marked (
A
) in the diagram) in the plant:
to the KNX bus cable at any point
to the RXB39.1 controller (RJ45 tool socket)
to the room unit (RJ45 tool socket)

The tool socket is a proprietary socket.
A Siemens connecting cable must be used (e.g. PXA-C1).
When connected to Ethernet, the device on the other end may be damaged
!
The tools ETS and ACS, even if connected to a tool socket, require an interface:
RS232-KNX interface (ETS)
USB-KNX / EIB interface OCI700 (ETS, ACS).
The "HandyTool" is connected to the tool socket of the room controller or to the
tool socket of the room unit (QAX…, RXZ90.1) (
B
).
If you use OCI700 as an interface, it is connected to the service plug of the
controller or of the room unit.
As long as the OCI700 is connected to the service plug, it must be sup-
plied by the computer via the USB interface
. Otherwise the LCD display of
the room unit will turn dark and the controller will switch to addressing mode.
