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#[^]

Solution 2

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 https://cdn.shopify.com/s/files/1/2482/2334/files/Manual_de_usuario_YP200.pdf?4035985435804019145
anexo codigo


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

            try
            {
                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;
                serialPort1.Open();
                serialPort1.Write("02(hex)B03(hex)");
            }
            catch (Exception ex)
            {
                MessageBox.Show("MENSAGE:",ex.Message);
            }

        }
        void sp_DataReceived(object sender, SerialDataReceivedEventArgs e)
        {
            MessageBox.Show("sp_DataReceived");
            if (this.Enabled == true)
            {
                MessageBox.Show("Enabled");
                Thread.Sleep(500);
                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.

serialPort1.Write("02(hex)B03(hex)");

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).
