Gurux DLMS for Java

Hi,

I am able to connect the meter from GXDLMSDirector and read all the data. But I am having some problems when I am trying to connect it from the client application. I am using -h ip -p port -c 16 -r ln -i HdlcWithModeE as program argument and it gives me error "gurux.net.GXNet cannot be cast to gurux.serial.GXSerial"

GXDLMSDirector parameters are:

Hi,

Mode E is used with optical probe and it's not used with TCP/IP. Change HdlcWithModeE to HDLC if you are using TCP/IP or UDP connection.

Hi,

Thanks for the reply.

I have just changed the interface to HDLC in both GXDLMSDirector and the argument in the program. I am able to read the from GXDLMSDirector again. However, I am not able to read it from the client application. It gives the following output. I double checked ip/port.

Hi,

When you select the meter in GXDLMSDirector you can see command-line parameters it the right side. Try with them. I believe that you haven't give the server address.

Hi,

I couldn't find any command-line parameters in GXDLMSDirector when I select the meter from the left side.

I assumed the server address that you have mentioned corresponds to physical address in the GXDLMSDirector. I added - s 100 to the argument but it still cannot connect to the meter.

Hi,

I just figured it out that I need to calculate the correct value of server address. It's working now.

Thanks for your help.
