byte will be exchanged when HMI sends command, even
though the starting Bit is 3A when sending data, it is
needed to input 3A00.
Set end Bit. Because the value of high byte and low byte
will be exchanged when HMI sends command, even
though the end Bit is 0D0A when sending data, it is
needed to input 0A0D.
