Biamp control systems with a LAN port are able to control the Kindermann Klick & Show:
Attached you will find a project and a device file to be used for this integration.
The project file can be used as is, or you can use it as inspiration for your own project.
The way the Klick & Show works with Biamp is easy to understand; if you take a look in the Feedback section in Project Designer you can see that the Click & Show button is pressed when the button is active and that the button appearance is changing accordingly.
