DLMSDirector

I'm trying to read a Landis+Gyr E450, it comes with a paper saying its DLMS firmware version is v5.22 and its reading key is 00000001. I downloaded the latest manufacturer info in GXDLMSDirector and just changed the authentication settings to low/high and setting the password as it is in the paper I got but I don't get any response from the meter.

I'm trying to read through optical port and the meter is from Spain in case this is relevant information.

Regards,

MA

Now I got an error saying Invalid Block number. it is 8 and it must be 1. What's the cause of this error?

Hi,

Select Properties in GXDLMSDirector and check "Logical Name referencing".
New meters of L+G are supporting Logical Name Referencing. Older meters are supporting Short Name
referencing and that is a default.

If connection fails we try to send disconnect message and that causes this error what you see.
We will fix this so disconnect message is not send if connection initailize fails.

BR,

Mikko
