Page 3: Application
1 Application The KNX IP BAOS 774.1 secure is a universal interface to the KNX bus. BAOS is an acronym for “Bus Access and Object Server”. Communication to KNX is possible both on telegram level (KNXnet/IP Tunneling) and on data point level (KNX Application Layer). Clients can directly access KNX Group Objects via either a Binary Protocol (over TCP/IP or UDP/IP) or via JSON (Java Script Object Notation) Web Services. -

BAOS SDK and the free download can be found at www.weinzierl.de. 2 Installation and connection The KNX IP BAOS 774.1 secure is designed for installation on a DIN rail with a width of 1 unit (18mm). It features the following controls and displays: ❶... -

The actually selected connection number is indicated by flashing (1x…10x) of the LED Mode ❺. An available BAOS connection is indicated by a green LED and a used BAOS connection is indicated by an orange LED. © 2024 WEINZIERL ENGINEERING GmbH Seite 5/27... -
Page 6: Reset To Factory Default Settings
In the factory default settings, the device has the physical address 15.15.255 and no group addresses are connected. Also, KNX Data Security is disabled and the initial key (FDSK) must be used for secure commissioning. © 2024 WEINZIERL ENGINEERING GmbH Seite 6/27... -
Page 7: Factory Default Settings
Encrypted telegrams are longer than the previously used unencrypted ones. For secure programming via the bus, it is therefore necessary that the interface used (e.g. USB) and any intermediate line couplers support the so called KNX Long Frames. © 2024 WEINZIERL ENGINEERING GmbH Seite 7/27... -

See section “ETS database – Additional individual addresses”. Like all programmable KNX devices, the KNX IP BAOS 774.1 secure has a individual address with which the device can be addressed. This is used, for example, by the ETS when downloading the interface via the KNX bus. -
Page 11: Programming
7 Programming The KNX IP BAOS 774.1 secure can be programmed by the ETS via different ways. 7.1 Via KNX bus For this purpose, the device must only be connected to the KNX bus. The ETS requires an additional interface (e.g. USB) to the KNX bus. Via this way, both the individual address and the entire application including IP configuration can be programmed. - Page 12 By clicking the gear next to “Automatic” the specific options appear. Here, the selection “Direct IP connection if supported by target device” can be selected. The download then takes place directly in the device and is not visible in the ETS group monitor. © 2024 WEINZIERL ENGINEERING GmbH Seite 12/27...

KNX IP BAOS 774.1 secure (www.weinzierl.de) or from the ETS online catalogue. The KNX IP BAOS 774.1 secure supports KNX Data Security to protect the device against unauthorized access from the KNX bus. If the device is programmed via the KNX bus, this is done with encrypted telegrams. - Page 14 The initial key is reactivated after a reset to factory default settings. The serial number in the certificate enables the ETS to assign the correct key to a device during a download. © 2024 WEINZIERL ENGINEERING GmbH Seite 14/27...

“Properties – Settings”. If the frame of the text field changes its colour to red after entry, this indicates that the address entered is already being used. The changes are only applied in the device after download. © 2024 WEINZIERL ENGINEERING GmbH Seite 16/27... - Page 17 Make sure that none of the specified addresses are already used in your KNX installation. © 2024 WEINZIERL ENGINEERING GmbH Seite 17/27...

IP Address The IP address of the KNX IP BAOS 774.1 secure must be entered here. This is used to address the device via the IP network (Wi-Fi). The IP addressing should be coordinated with the administrator of the network.
- Page 20 Subnet mask of PC: 255.255.255.0 The KNX IP BAOS 774.1 secure is located in the same local network, i.e. it uses the same subnet. The assignment of the IP address is restricted by the subnet, i.e. in this example the IP address of the IP interface must be 192.168.1.xx, xx can be a number from 1 to 254 (with the exception of 30,...
