Siemens RXL24.1 – Room controller CM2N3878en_07
Building Technologies 2015-12-23
The connection terminals for the bus are detachable plug-in screw-terminals. All
other terminals are fixed..
The RXL24.1 controller communicates with other devices via the following
interfaces:
• PPS2 interface (proprietary) for the exchange of data with the room units
• Bus (terminals CE+ and CE-) for communication with:
− PX/KNX interface (to Desigo Insight)
− Interface OCI700 (to Synco)
− Other RXL controllers
To facilitate commissioning, the Synco ACS tool can be connected at three
different points (marked (
A) in the diagram) in the plant:
− to the bus cable at any point
− to the RXL2… 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 ACS tool, even if connected to a tool socket, requires an interface (OCI700).
• The "HandyTool" is connected to the tool socket of the room controller or to the
tool socket of the room unit (QAX3…, 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
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.
