7.2 Open interface
At startup, the PRAESENSA system controller generates a number of certificates. One
certificate is used to setup the TLS (secure) connection and offers an Open Interface client to
make sure it communicates with the right PRAESENSA system controller.
To do so:
1. Below Security, click Open interface:
2. Click the Download certificate button:
– Depending on the web browser type (e.g. Firefox, Edge, etc.) you will be asked to
open/install/save the .crt file.
– Follow the onscreen instructions.
3. Activate the certificate on your PC and follow the onscreen instructions.
4. Go to >
Optional: Using the Open Interface, page 132
IMPORTANT: each time the PRAESENSA system controller is reset to default, the system
controller generates new certificates. In that case, the previous described procedure needs to
be done, again.
