Landis+Gyr E650 setup

If I have an out-of-box unit, can I use tcp/ip to connect using GXDLMSDirector with the correct IP:port setting?

Shortly, YES.

You need Communication unit CU-E20 / E21 / E22.
If you have that, you need to enable it.

If you can access your meter example using optical head, change Logical Device address from 0 to 1 and
you can check your communication module settings. Example listening port number.

The unit was configured with an IP address of
When connecting, I get the following error message:

"No connection could be made because the target machine actively refused it"

Where am I going wrong?
