EXAMPLE
#M0001G00se00 - 17.4|01 0.535|02 0.000|03 -
1.89|04 0.0|05 0|B11D;
This protocol is identical with the Sommer protocol except that the index of the measurement values
starts at 0 instead of 1.
This protocol has been implemented for compatibility reasons: When a Sommer device with firm-
ware < 2.0 is updated to version 2.x the protocol is automatically set to Sommer old. Thus, the setup
of a connected data logger does not have to be adjusted.
