How to write in the LED moving Board in C#?

Question

please understand that I am really in need of help. I want to write over the Moving LED board which can be connected through serial connection.
. This is the image of the board. There is a software provided by the company from which this board is bought.
This is the image of the software GUI. I tried making a C# GUI for serialPort connection. But however, I could not see the output in the board. When making virtual serial ports and communicating through TeraTerm, The program works perfectly. I even have used HEX code converter. But I am unable to write in this board. Plese have a look at my code and help me.
This is the picture of GUI I created. The code is as follows. Please suggest me. Thanks in advance

Hi there,

Generally speaking the programing process has the below steps.

-Enter the number of LEDs in width and height on your LED display.
-Select module type – this means the distance between the centers of two LEDs placed alongside
-Select luminance.
-Select frequency of refresh.

This also changes with respect to the manufacturer , make sure you enquire about this to them to guide you in right way.
