Negative distance values are output in two’s complement notation.
The value for the signal quality varies between 0 and 1024. 0 means a bad
signal quality while 1024 indicates a very good signal quality.
Examples:
Distance = 4,996 m, SF1
dec:
004.996<CR><LF>
hex:
<SPACE>001384<CR><LF>
(= 4996 mm × SF1)
dec+sig: 004.996_000005<CR><LF>
(bad signal quality)
dec+sig: 004.996_000985<CR><LF>
(good signal quality)
Distance = 4,996 m, SF10
dec:
049.960<CR><LF>
hex:
_00C328<CR><LF>
(= 49960 = 4996 mm × SF10)
dec+sig: 049.960_000005<CR><LF>
Error case
dec/hex:

ST – display/set measure time [0..25]
Measuring time is directly conditional on the selected measuring mode. As a
general rule, one may say: the poorer the reflectance of the surface of a
particular target, the more time the LDM41E and LDM42E will require to
determine the distance with specified accuracy. For example, if error message
E15 is output because of poor reflectance and insufficient time to measure,
this latter setting must be increased.
