Why does the KNX device not allow for its programming via the bus?
Make sure that you use the correct application version. To do this, check if the item number of your device matches the item number of the application. As a rule, the application lists the item number of white devices. If your device is a different colour but the same type, choose the white item number regardless.
Make sure that there is bus and auxiliary voltage. This must be checked by an electrician.
If a line/area coupler is used: Set it to ‘forward’.
Assign an address to your device. The factory default is 15.15.250/255. The address of the device must not be the same as that of the programming interface.
Why does the media coupler KNX RF LC-TP not integrate in the current KNX project? An error message appears constantly: ‘Validation failed. The KNX RF LC-TP device is not compatible with the medium type of the line.’
KNX RF can only be integrated in RF lines. Click on the ‘Add lines’ buttons and select ‘RF’ as the medium.
For lines that are already available, you can use the ‘Properties’ window to change the medium type to ‘RF’ later.
