Hi,

I've an existing Actaris Electricity meter system, that was installed by another firm so I've got only few information. I'm trying to listen into the communication throught the serial port and I see that the SNRM request is like this:
7E A0 0A 00 22 00 CB 03 93 69 CE 7E

I'd like to use GXDLMSClient to read data from the meters, but if I set the parameters like this:
GXDLMSClient client = new GXDLMSClient();
client.UseLogicalNameReferencing = true;
client.InterfaceType = InterfaceType.HDLC;
client.ClientAddress = 1;
client.ServerAddress = GXDLMSClient.GetServerAddress(17, 101);
client.ServerAddressSize = 4;

I send the SNRM request like this:
7E A0 0A 00 00 22 CB 03 93 55 0E 7E

Why is 22 value of the 4 sized server address is different?
What is the right way to handle this proble?

I've changed the getServerAddress to return the bytes in the requested order and this seems to work form my application.
