Notes:
Two byte (integer) values (for example, SN, CHK) are in lease significant byte, most significant byte
order. For example, Byte 4 = 57 (39 HEX), Byte 5 = 48 (30 HEX), then SN = 12345 (3039 HEX).
VCO,HCO = Mechanical offsets between the sensor’s electrical center and the target’s mechanical
center. For factory use only.
CHK (Checksum)) = Two’s complement (negation) of the sum of the bytes 1 to 20.
