You need to do research via Google Search. To get you started, here is the question I asked it: c# example of reading values from the Digital weight scale yp200 braunker[^] ... there are a few results

Here is a helpful answer, but not for that brand and model that you are asking for help with. Follow the advice given: How to Communicate with digital scale using C#[^]

You can also download the (Spanish) manual of the device, wherein the serial protocol is concisely described.

I downloaded the manual, reviewed the codes, however I have not achieved communication
anexo codigo

private void Form1_Load(object sender, EventArgs e)
string data = "02(hex)B03(hex)";

serialPort1 = new SerialPort("COM8", 9600, Parity.None, 8, StopBits.One);
serialPort1.Handshake = Handshake.None;
serialPort1.DataReceived += new SerialDataReceivedEventHandler(sp_DataReceived);
serialPort1.ReadTimeout = 500;
serialPort1.WriteTimeout = 500;
catch (Exception ex)

void sp_DataReceived(object sender, SerialDataReceivedEventArgs e)
if (this.Enabled == true)
string data = serialPort1.ReadExisting();
this.BeginInvoke(new DelegadoAcceso(si_DataReceived), new object[] { data });

I suggest you to first use a reliable terminal emulator program (e.g. PuTTY) to attempt the communication with the scale.
Then you can write your application.

You have to write the BYTES 0x02, 0x42, 0x03, not the string "02(hex)B03(hex)".

I tried the communication successfully, however when I made the request by command I did not get a response

You could also try realterm, if you need to send binary data (the manual is not clear about what you should send in order to obtain the listed answers).
