Hi all,

I need help in trying to extract data out from my power meter using Arduino Mega through RS232 interface cable. Does anyone know how can I write serial commands to my power meter so that it could respond ? I have tried using Serial.print examples but they do not work. The serial monitor does not print the measured reading reflected on the power meter. The power meter I am using is Yokogawa Power Meter CW121.

Please help. Thank you

What RS-232 to TTL adapter board are you using? Is it working properly?
