Hello.
My EMH LZQJ-CX is connected via a serial port server (Moxa). The serial port server operating mode is TCP Server. GXDLMDirector connects to that meter without a problem. I copied command line parameters from GXDLMDirector and tried to use them as parameters for Gurux.DLMS.Client.Example.Net. Unfortunately, this time the meter did not respond to the SNRM request. I have compared SNRM frames sent by GXDLMDirector and Gurux.DLMS.Client.Example.Net, and they are different. I wonder why.
Here are the frames sent by both programs:

Hi,
Hi,
EMH is not using DLMS standard way to count the serial number. You need to modify the source code.
Change this line:
settings.client.ServerAddress = GXDLMSClient.GetServerAddressFromSerialNumber(int.Parse(it.Value), 1);
to this:
settings.client.ServerAddress = GXDLMSClient.GetServerAddressFromSerialNumber(int.Parse(it.Value), 1, "SN%10000+256");
