The data string has the following structure (in Hex):
b1 b2 b3 E4h b5 E4h 0Dh 0Ah,
where:
b1 – type of measurement;
b2 – sign of measurement (1 – minus, 2 – plus);
b3 – LSB of result;
b5 – MSB of result
Result of measurement = MSB * 256 + LSB
In both standard modes, when three parameters are measured, the
module will generate three data sequences in one block, where
the first one presents results of distance measurement, the second
– results of azimuth measurement, the third – result of inclination
measurement.
The data string will look like:
b1 b2 b3 E4h b5 E4h
b7 b8 b9 E4h b11 E4h
b13 b14 b15 E4h b17 E4h 0Dh 0Ah
Where bytes contain the following information:
b1, b7, b13 – type of measurement
b2, b8, b14 – sign of measurement (1 – minus, 2 – plus)
b3 – LSB of the result for the first type of measurement
b5 – MSB of the result for the first type of measurement
b9 – LSB of the result for the second type of measurement
