DLMSDirector

When a GXDLMSDirector device is set to GMAC authentication mode the password box is enabled, and connections won't work unless something is entered in that password box. It doesn't seem to matter what you put in the password box, as long as you don't leave it blank. Is this a bug, or is this password used for something I have missed?

Password for GMAC authentication

Hi,

Password is needed with GMAC. Password is used as Secret. Are you using simulator or real meter?

Password for GMAC authenticatio

Do you mean it is needed during the encrypted data exchange. It isn't used during the initial 4 step association, as it is for the other authentication types. I am working with meter code that is in development.

Password for GMAC authentication

Hi,

You are right. I remember wrong. :-(
Password is not needed for GMAC, because system title is used. We'll update this to GXDLMSDirector so it's not asked.

BR,

Mikko
