Checksum calculation method
All bytes of data from the size to the parameters is added together, and the twos complement of the result in hexadecimal for-
mat is subtracted from 0x0100 to obtain the checksum.
Example) For the command "1D 0007 01 10 00 02 0A CS"
0x00 + 0x07 + 0x01 + 0x10 + 0x00 + 0x02 + 0x0A = 0x24 ---> 0x0100 - 0x24 = 0xDC
