KNX BAOS Module 830.1 secure

BAOS Modules from Weinzierl are a cost effective way to make devices KNX-capable. The modules serve as a serial interface to KNX. The compact KNX BAOS Module 830.1 secure as pin compatible successor to the proven module 820 provides support for up to 1,000 data points, KNX and BAOS Security. The module includes a certified KNX stack (System B) and can be configured with the ETS. A generic ETS database allows a quick start. Individual ETS entries can be created.
For developers, a BAOS Development Board with a Cortex M0+ controller and sample code is available. The free version of Net’n Node 5 supports the new module.
Samples are available to be supplied promptly. If you require any further information, please contact us at support@weinzierl.de.
KNX connectivity on a small footprint
Our BAOS modules integrate a complete KNX node including a transceiver and a microcontroller 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.
Customer Benefits
- Low investments
- Optimal price-performance ratio
- Shorter development time
- For modular device concept
- Simple baseboard design
- Free demo software available
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.
Integrated Object Server
The benefit of the Object Server in the KNX BAOS Modules is the logical decoupling of the application from the KNX communication. The application can access the values of the communication objects without any knowledge of KNX telegram formats or KNX addresses used in the current installation. The KNX BAOS Module 830.1 secure module offers up to 1000 data points.

The module autonomously generates and sends group telegrams. Received group telegrams will be interpreted in the module and the values will be stored in the addressed communication objects. The complete download of ETS is handled within the module.
KNX BAOS Starter Kit
The new Weinzierl KNX BAOS Starter Kit allows a quick start into KNX development. The development board provides a socket for the BAOS Modules and contains a user programmable micro (Cortex M0+) for the application as well as some connectors, LEDs and buttons for development purpose.
The KNX BAOS Starter Kit contains:
- 1x development board
- 1x KNX BAOS Module 830
- 1x KNX BAOS Module 832
- 1x USB-C cable
- Development software (Download)
