The KNX IP BAOS 773 is used as Interface for connecting to KNX both on telegram level (KNXnet/IP Tunneling) and on data point level (KNX Application Layer). Clients can directly access Group Objects via either a Binary Protocol (over TCP/IP or UDP/IP) or via JSON (Java Script Object Notation) Web Services. The device is configured with the ETS and supports up to 250 Group Objects. 10 simultaneous client connections are supported.

BAOS is an acronym for “Bus Access and Object Server”. It is possible to connect to the KNX bus everywhere over LAN. Bus connection over the internet with KNX IP BAOS 773 is also possible. The device supports 5 simultaneous KNXnet/IP tunneling connections.

The buttons are for diagnostic purposes. The LEDs indicate the operating status and communication errors on the bus. Power is supplied via the KNX bus.
