Hi,

I have tried to use the AMI4 and connected to a meter. the connection was via tcp and it worked.

Now im trying to connect to the meter via serial but i can't seem to initialized the serial connection to meter even with the correct serial parameters.

Do i need to make/use the scripts to connect to the meter? if so what does the script expect as an output and i am assuming that the script is in c#

Thank you very much for your support

Hi,

You need to select the serial port that you want to use from the agent settings.
Change the interface from WRAPPER to HDLC. Then set the correct client and meter address so you can read the meter.

The easiest way to do this is to read the meter using GXDLMSDirector and then use the same settings with AMI.

The new version from AMI will be released next month.

Hi Mikko
That is noted.

Also ive just realized that even via tcp im having issues setting up a connection whenever the authentication is anything other than none.

for both tcp and serial devices how do i setup authentication? Via device templates and also the device? Because as far as i can observe the agent doesnt have connection properties on setup. and on edit we can only change push events, gateway, and autoconnect which i dont think is the setup i need.

Hi,

You need to create a new template for the new authentication and add it to the agent.

You can't just change the authetication level in agent.

This is done because usually the access rights and available object might change when the authentication level is changed.
