RLY-8 control over USB

I have a problem with controlling this product over USB:
https://www.dfrobot.com/product-1218.html
In the communication protocol PDF, I found the command format. But how do I have to send these commands to the device? I tried it byte after byte starting from the frame head. What are the settings of the serial port (parity, stop-bit etc.)?
Im working on windows on visual studio and made a C#-Project. Here is the necessary code snippet:

Im working on windows on visual studio and made a C#-Project. Here is the necessary code snippet:
Code: Select all
_serialPort = new System.IO.Ports.SerialPort();
_serialPort.PortName = "COM4";
_serialPort.Parity = 0;
_serialPort.BaudRate = 115200;
_serialPort.StopBits = StopBits.Two;
_serialPort.DataBits = 8;
_serialPort.ReadTimeout = 50;
_serialPort.WriteTimeout = 50;
try {
_serialPort.Open();
}
catch (System.IO.IOException e) {
Console.WriteLine(String.Format("Exception with message {0} occured", e.Message));
return;
}
_continue = true;
Console.WriteLine("Type QUIT to exit");
while (_continue) {
message = Console.ReadLine();
if (stringComparer.Equals("quit", message)) {
_continue = false;
}
else {
byte[] bytestosend = { 0x55, 0xAA, 0x01, 0x02, 0x00, 0x01, 0x00, 0x03 };
_serialPort.Write(bytestosend,0,bytestosend.Length);
}
}
