Example: Suppose you want to set the maximum power to 213.45W. Since 1 represents 1mW,
213.45W translates to 213,450 in decimal. With 4 bytes in Hex, that would be 0x000341CA. Since
the bytes are ordered in little-endian format, 0xCA would be the 3
rd byte, 0x41 the4 th byte, 0x03 as 5 th
byte, and 0x00 as the 6 th byte.
