[DATA (START)], [DATA (START + 1)], …, [DATA (END)], [CHK], 03
[CHK] = Lower 8bits of “4A + ([DataLenH] +80) + [DataLenL] + [SLV] + [START_H] + [START_L] +

02, 4A, [DataLenH], [DataLenL], [SLV], [START_H], [START_L], [END_H], [END_L], [DATA (START)],
[DATA (START + 1)], …, [DATA (END)], [CHK], 03
[CHK] = Lower 8bits of “4A + [DataLenH] + [DataLenL] + [SLV] + [START_H] + [START_L] + [END_H] +
[END_L] + [DATA (START)] + [DATA(START + 1)] + … + [DATA(END)]”
e.g. Sending data to write “23” to address 0010 of IC (Slave address: 21[h])
