Our BAOS modules integrate a complete KNX node including a transceiver and a micro-controller running the certified Weinzierl KNX Stack. Possible applications for the modules are the integration into sensors, actuators, communication and even visualization devices. Communication with the modules takes place via the serial BAOS protocol in FT1.2 frame format. In addition, the FT1.2 protocol enables the transmission and reception of KNX telegrams in the cEMI (Common External Message Interface) format.

Quick start into KNX device development

For a quick start into the development of KNX devices we recommend our KNX BAOS Starter Kit. It contains a development board and two KNX BAOS Modules. For the development board we provide a free demo project which implements the BAOS protocol and a simple application. A demo tool for Windows® is available to test the BAOS protocol from a PC.

A generic ETS (Engineering Tool Software) database is available for setting the data types and linking the communication objects. Of course, it is also possible to create individual databases for your devices. So the KNX BAOS Modules allow a fast development of full value KNX devices which of course can be certified by the KNX Association.
