Connection of the CubicleBUS with COM15
The figure below shows the connection of external CubicleBUS modules to the
SENTRON WL with COM15:
● Connect the external CubicleBUS modules using the supplied 0.5 m CubicleBUS cables
and integrate them into the system.
● Provide the CubicleBUS with a terminating resistor.
● Connect the power supply to the X3 interface.
