According to the following document on the page 22, I need to send the hex code of 0x61 and 0x00 in order to get the phase I reading of the electricity meter.
I would to write a simple serial code to send this to the meter from the computer maybe written in VB by Visual Studio and ask the meter to give me its reading phase I.
I'm new in writing serial port open/close and these stuff. I found the following serial code in here
However, this is basic, I have no idea how to start and write my own GUI file. Is there anyone who can walk me through this?
i just simply would like to get to know how to talk to a serial port. I believe DLT/645 is nothing but a special code command to start the communication!
