KNX IP BAOS 773 - KNX IP Interface with Object Server, 250 Data Points

KNX IP interface for the KNX bus, both at the telegram level (KNXnet/IP tunneling) and at the data point level (KNX application level). This allows clients to access group objects directly via TCP/IP or UDP/IP using a binary protocol. As an alternative protocol, Java Script Object Notation (JSON) is available for use in web browsers.

KNX IP BAOS 773 is used as an interface for connecting to KNX both at the telegram level (KNXnet/IP Tunneling) and at the data point level (KNX Application Layer). Clients can directly access group objects via a binary protocol (over TCP/IP or UDP/IP) or via JSON web services (Java Script Object Notation).

The device is configured with ETS and supports up to 250 group objects. 10 simultaneous client connections are supported. BAOS stands for "Bus Access and Object Server". It is possible to connect to the KNX bus anywhere via LAN.

Connection to the bus via the Internet is also possible with KNX IP BAOS 773. The device supports 5 simultaneous KNXnet/IP tunneling connections. The buttons are for diagnostics. LEDs indicate operating status and communication errors on the bus. Power is supplied via the KNX bus.

Two free SDKs are available for quick and easy integration of BAOS services into your projects. The first is the BAOS Binary SDK, a C++ implementation of the BAOS Binary protocol. The following systems are supported: Windows, Linux, Mac OS X, iOS

For integrating BAOS services into a web browser, we offer the BAOS Web Services SDK. This SDK is based on HTTP and JavaScript; BAOS services provide a simple JavaScript API. A generic ETS entry is available for all Weinzierl BAOS modules and devices. It contains a list of all available data points.

You can select a data point type and enter a name for each data point. Furthermore, a so-called DCA (Device Control App) is now available with the Weinzierl BAOS CSV Importer. The Weinzierl BAOS CSV Importer is available for all Weinzierl BAOS devices with a generic ETS product database and is a simple way to export the existing configuration of a generic BAOS database to a CSV file and import it into another project. This avoids tedious manual configuration.
