The RXB2... controllers communicate with other devices via the following interfaces:

PPS2 interface (proprietary) for the exchange of data with the room units

KNX / EIB bus (terminals CE+ and CE-) for communication with:
 PX/KNX interface (to DESIGO INSIGHT)
 Interface OCI700 (to Synco)
 Other DESIGO RXB controllers
 KNX / EIB compatible field devices (e.g. temperature sensor)
The tool socket (RJ45) must be connected only by a qualified electrician. The adjacent
terminal may be a live mains voltage conductor.
To facilitate commissioning, the tools ETS3 Profession or Synco ACS can be
connected at three different points (marked (
 to the KNX / EIB bus cable at any point
 to the RXB2... 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 ETS3 and ACS, even if connected to a tool socket, require an interface:
 RS232 KNX/EIB interface (ETS3)
 OCI700 USB-KNX / EIB interface (ETS3 , ACS).
 The "HandyTool" is connected to the tool socket of the room controller or to the tool
socket of the room unit (QAX3..., RXZ90.1) (
 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 supplied 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.
