Sorry
I have talked with supplier.
The supplier told me that the hardware is communicated in WinSock.
He use Delphi to example the data.
This hardware is used "sendto" and "recvfrom".
I need to define the data some parts are 8 bits and some are 16 bits.
Then the data will be 0xAA 0xAA 0x0d 0x01 0x64 0x00 0x00 0x00 0x02 0x01 0x02 0x01 0x01 0x5F 0x48 .

Would you mind telling me how can I receive the data?
