LRC Check:
Sum up the contents from “machine address” to “data content”, e.g. H01 + H03 + H10 + H00 + H00 + H02 = H16. Obtain 2’scomplement
HEA.

CRC (Cyclical Redundancy Check) is obtained by the following steps:
unsigned int reg_crc = 0xffff;
i = 0;
while (length--)
{ reg_crc ^= RTUData[i];
i ++;
for (j = 0; j < 8; j++)
{ if (reg_crc & 0x01) reg_crc = (reg_crc >> 1) ^ 0xA001;
else reg_crc = reg_crc >> 1;
}
}
return(reg_crc);
