VISA + C# + RS485 + carriage return

[mell90]

Hi, everybody!
I have an engine and I want to control it by means of rs485.

 wData = new SerialSession("COM7");
 wData.BaudRate = 9600;
 wData.TerminationCharacterEnabled = true;
 String Command = "AV10000"+"\r";
 byte[] bytes = new byte[8];
 int bWritten = ASCIIEncoding.ASCII.GetBytes(Command, 0,      Command.Length, bytes, 0);
 wData.Write(bytes);
 wData.Clear();

 through visa and c# there is no response

 Problem is "#0D" but I send it through "\r"

Through the terminal program everything works

If you know that you need to send #0D why are you deliberately sending \r  ?

Because in this case it sends "#0D" as a string and the engine to it doesn't react

And what does the engine documentation says needs to be sent?

[mell90]

For example "AV10000" + "carriage return"

via the terminal on the second picture I send

via the serialport c# it works also goog but not with VISA

serialPort.Write("AV10000\r");
