i need to read obis codes from an iskra mt860 but i can't connect to it because the gurux software doesn't receive reply from iskra. I'm trying to connect to iskra through serial communication RS485 on two wires, using a simple serial communication software if i send only one command: "/?!" or "/?serial_number!" i don't get reply but if i send two commands in sequence i get reply from the iskra, someone know what is the problem?
If i send one command:
/?! --> No reply
If i send two commands in sequence:
/?!
/?! --> I get reply
Next week i will go back to the company where iskra is installed and i will have one week to make it working...
Thank you in advance for help, and i wish to everyone a happy new year!
thank you for your answer, ok i understand but with gurux direct what settings i must to set to add \r\n on the connection request? I tried to connect to iskra with gurux direct but it can't get the reply from iskra...
Now can't do some test because iskra device is installed in another company that stay in a far city from me, so i must to wait next week...
I thought that if i set Start protocol to IEC, software uses IEC protocol to communicate with devices...
Gurux framework uses also IEC protocol to communicate with devices? Or it's not implemented?
There are ASCII and binary mode in IEC. DLMS is using that binary mode. We are not support that ASCII mode because there are so many variations between meters.
Ok thank you, I understood! In the following link i found specs of iskra MT860 and there is wrote that it supports also DLMS protocol, you can see it at the end of the page. http://www.telematicasistemi.it/prodotti/MT860
Next week i will do some tests with gurux dlms, thank you for your important support!

Hi,
You can't read ISKRA MT860 With GXDLMSDirector. MT860 is using IEC 62056 - 21, not DLMS.

Hi Denis,
Can you see DLMS label on the cover of the meter? If you look link below from Iskra web page there is nothing from DLMS.
