 How to Calculate Check sum.
Sum the value from “STX” to “ETX” and converts to ASCII(2byte) and transfer.
Convert the Sum value(HEX) to ASCII and transmit(28byte) .
ex) The sum HEX value from STX to ETX(02,30,31,52,43,57,54,03) is 1A6h.
Then, divide 1A6h by 100h(1A6h/100h). the rest of result is A6h.
Calculated remainder value is A6h, then convert A6h to ASCII, 41(A), 36(6), and transfer.
