KNX IP BAOS 771

The KNX IP BAOS 771 is used as interface to connect to KNX/EIB both on telegram level (KNXnet/IP Tunneling) and on data-point level (KNX Application Layer). BAOS stands for "Bus Access and Object Server". This device can be used with ETS as a programming interface. As ObjectServer the device supports up to 250 data points. It is possible to connect to KNX/EIB-Bus (telegrams) as well as to data points (communication objects) from everywhere via LAN. Connection over the internet is possible, too. The IP settings as well as the data points can be configured with ETS software. The device requires an external power supply or can alternatively be powered via Power-over-Ethernet (IEEE 802.3af) directly from the switch.

  BAOS SDK

For quick and easy integration of BAOS services in your own projects there are two free SDKs available. First, the BAOS Binary SDK, a C++ implementation of the BAOS Binary Protocol. The following systems are supported:

  • Windows
  • Linux
  • Mac OS X
  • iOS
For the integration of BAOS Services in a Web browser, we offer the BAOS Web Services SDK. This SDK is based on HTTP and Java script, the BAOS Services provides a simple JavaScript API.
