Hi,

Hi,

You can change the ciphering key from GXDLMSDirector selecting "Security Setup". and "Update key".
Select the key that you want to update.
You need to know the correct Master Key (KEK) to update the key.

After the key is updated to the meter. Close connection. Update the new key to the GXDLMSDirector device settings and make a new connection.

We are improving the server examples so keys are shown on the console after they are updated.
BR,
Mikko
