Aquamaster 3 Modbus-Serial 485
I wonder if anyone can help me with my communication via Modbus Serial.
I am using a USB adaptor with 2 wires conection to communicate with the AM 3.
The software I am using is ScadaBR and when i try to get values from the software it shows "can't connect with server".
I saw the settings and its all according to AM 3 ones.
I have seen a similar post and they were talking about resistors, I am not using any, do you think it might be the problem? Because I know that AM 3 has got the sleep mode after 10 sec.
Thank you for all the help you can give.
