EKM Metering

Hi Jameson, ok thank you i understand.

You were right about flushing the buffer, now im still dealing with the noise.

Hi Jameson, I'm not using any resistors at all, because of the distance isn't that far and since i got understood neither you connect at both sides or none and i'm not sure how to connect on the meter side or if the meter already has these include, so i decided to connect none. But could you give me...

OK Jameson thanks for your quick reply! I will check that out, also i was checking the data on the Return string and i noticed the voltage data came { 0xb1,0xb2,0x35,0x32} instead of {0x31,0x32,0x35,0x32} like it would normally be according to your meter communication parsing. Any idea of why this '...

Hi, i could communicate to the meter. I want to check the Voltage every 5 seconds, so i send the Request every 5 seconds. The first "Return" is correct but from this point on i´m not getting the right data or i'm not getting it in the right order (i.e. where i should see the voltage i see ...

Hi Jameson,

My meter number is 15423 and this is the string i have generated for the request

const BYTE Request[] = {0x2F,0x3F,0x30,0x30,0x30,0x30,0x30,0x30,0x30,0x31,0x35,0x34,0x32,0x33,0x21,0x0D,0x0A};

is that ok?

Thank you.

Hi Jameson thank you for your reply, Yes, i understand about the "Close String", that is what i actually ment by "closing". But i´m really doubting about the sequence, i mean, do i need to send "Request", wait for the "Return" , send the "Read String"...

Hi, I´m working on a project using your EKM Omnimeter I v.3 to monitor a photovoltaic Solar power system and i want to access the EKM through my own embedded solution. I am using a pic 16F877A with a max485 but i have some doubts about the parsing and the communication protocol. 1) The request strin...
