Hi
I trust every body is well, I first want to understand DLMS before I go to Arduino IDE platform. So I have downloaded GXDLMSDirector and I want to setup it for serial coms and to talk to Kamstrup meter. I can add a Device, selected kamstrup as manufacturer. I can connect successfully with the default setting but when I want to read it the meter does not respond. The authentication key and encription key are blank as default. What setting am I missing?

Hi Gerdus,
Hi Gerdus,
Kamstrup needs that some extra settings are set. Check Initial settings from here.

Note! Server and client addresses might change if you are using some other communication channel than the optical head (probe).

HDLC is selected for interface and it's correct. I can't remember the client and server address for the RS-485, but you can find that from the meter manual.

Hi
Hi
When I use the metertool from Kamstrup there is DLMS address (32), when I use that address I do not even get a Successful connection. On the the GXdirector I set it to 20(hex). Does the meter auto detect which protocol to use on the RS485 port. With KMP protocol it work.
I Found this in Kamstrup

Hi,
Thanks for letting me know that you can connect.
RS-485 default values are added to the initial settings help page. It's easier to remember next time.
