LRC CHK（check sum）
The LRC (Longitudinal Redundancy Check) is calculated by summing up, module 256, the values
of the bytes from ADR1 to the last data character, then calculating the hexadecimal representation
of the 2’s-complement negation of the sum. The ELC supports LRC CHK per the Modbus Serial
specification
