Hi, Your settings are not…

Hi,

Your settings are not correct. Try to connect with GXDLMSDirector. After you establish the connection to the meter, you can view the proper command line arguments and use them as needed.

Hi Kurumi, Thanks for your…

Hi Kurumi,

Thanks for your response.
I already tried to establish a connection using GXDLMSDirector, but I’m getting the same issue — the connection times out and no reply is received from the meter

Do you have any suggestions for what settings I should try next
am using the itron ACE6000 , plugged in using an optical port electric meter , thank you

Hi, It has been a while…

Hi,

It has been a while since anyone has tried to read ACE6000. Its older meter and DLMS protocol have changed a lot after that.

Select Actaris Electricity as a meter manufacturer. Let the authentication level be None and change the Interface from HDLC to HdlcWithModeE.
Then try to connect to your meter.

If you are not receiving any reply, change the Interface to HDLC and try with different baud rates.

Mikko

Hi, Thanks for the…

Hi,

Thanks for the suggestions. I have tried the configuration you recommended for the ACE6000 meter
Unfortunately, I am still not receiving any reply from the meter.
I also attempted to connect with a different meter, a CLOU ELECTRONICS CL730D22L, using the same methods. I am experiencing the exact same problem—no communication is established.

Please let me know if you have any other suggestions. I'm ready to try further troubleshooting.

Thank you,

Hi, Your serial port…

Hi,

Your serial port settings are at least wrong. I don't know what baud rate your meter is using, but it should be like:
COM5:9600:8None1

For Clou you need to select "Shen Zhen Clou Electronics Co Ltd" as a meter manufacturer.

BR,
Mikko

Hi, Thank you for your reply…

Hi,

Thank you for your reply. I just want to clarify that my serial port settings are already set to COM5:9600:8None1, and for the manufacturer, I have selected Shen Zhen Clou Electronics Co Ltd.

Unfortunately, I am still experiencing the same problem. Could you please advise what else I should check?

this is the command i get from the GXDLMSDIRECTOR
-S COM5:9600:8NoneOne -r sn -s 3 -a Low -P 00000000 -w 1 -f 128 -t Verbose

Best regards,

Are you connecting with an optical probe or using RS-232?

Hi, If you are connecting…

Hi,

If you are connecting with an optical probe, change the interface from HDLC to HdlcWithModeE and try again.
