We are trying to read the data from the Saral Meter which has a microusb over RS 232 and the meter is not responding to data being sent via the Gurux software using the DLMS COSEM protocol. Attaching the screenshots to help you understand the parameters we are using at input and the oscilloscope which shows that data from the PC. The transmitted data can be seen perfectly till the last mile but the Rx pin of the meter just does not throw out any data. Are we missing anything here?

Hi,
Hi,
Try to change the physical address from 256 to 1. I believe that one of your settings is wrong or then the reason is in serial port settings.
