The SV command returns the software version of the sensor.
There are three blank spaces between $WI,SV= and the beginning of the software version.
For software versions using the format 7.5 two blank spaces will follow.
FT may release incremental software versions with the numbering format 7.5.1, in this case
there will be no blank spaces following the software version.
