Bus Interface Modules (BIM)

BIM M13.. series

The bus interface modules are printed circuit boards consisting of the chipsets (TP-UART + KNX microcontroller) mounted with all necessary components.

The BIM M13.. series of bus interface modules provides state of the art flash technology; this enables the application designer to utilize modern tools leading to shorter development times.

The application interface includes the PEI, Reset, two PWMs and one processor port.

The BIM M13.. modules contain the BCU 2.5 system software compliant to the KNX specification.

In addition the BIM M13.. series is designed with a high degree of hardware compatibility to BIM M11.. series enabling to replace the BIM M111/113/115 in existing hardware and in most cases reducing the development effort to the application software.
