Check sum
The checksum (CS) represents the sum of all values of the ASCII characters, the last two digits of which are
used.
Example:
Temperature compensation off

Check sum (ASCII values):

Measuring mode absolute / relative
Absolute: The sensor refers to the factory calibration and provides absolute measured data in 0.1 mm
steps. Should the object move into the sensor's blind region (less than 3 mm distance) the output provides
the value 0. In the case of no object being within the measuring range the output shows the value 4095.
Relative always provides the sensor-internal unit: 1 unit = 1/4096 of the configured measuring range (range
of values: 0...4095). When the measuring range has been limited by Teach-in the range of values (0...4095)
applies to the actually used range. The resolution of the measurement has thereby not been improved.
Should the object move into the sensor's blind region (less than 3 mm distance) the output provides the
value 0. In the case of no object being within the measuring range the output shows the value 4095.
Binary format
The binary format is only used for the permanent periodical data output in order to transmit the data
measured with the maximum data rate. For that reason the binary format is very compact with only a
minimum of overhead.

Special features of the permanent periodical data output
Data output is stopped by sending the reset command or by switching the sensor off.

Measuring range
Averaging
By averaging a higher number of measurements both the repeat accuracy and the resolution can be
improved. The measuring speed is thereby reduced.
Time per measurement = 7 ms, this corresponds for 8 measurements 8 x 7 ms = 56 ms.
Average algorithm: Floating average

Bit 7 is 1 (Mark for start of data string)
Bit6 = 1 → Object within measuring range
Bit6 = 0 → no object within measuring range
Bit 0...Bit 5 are Bit 6..11 of the measured value
Bit 7 is 0
Bit6 = 1 → Echo width wide (big signal reserve)
Bit6 = 0 → Echo width narrow (small signal reserve)
Bit 0...Bit 5 are Bit 0...5 of the measured value
