Siemens connecting cable
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) (
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.
