VENTUS_Release_V28_SVN_0415                                                              2016/05/13

· NMEA protocol: VENTUS responds to unknown commands with dummy telegrams (optional)

· NMEA protocol: return value in the respond of some commands can be set in the EEPROM

· NMEA protocol: output rate can be set between 10ms and 10s, default: 10s

!Attention! : The unit of the output rate has changed from seconds to milliseconds!

· Analog outputs: error handling corrected

· Analog outputs: If the given value is out of (the adjustable value-min/value-max) range, the analog output is set to the min current or the max current value respectively. Formerly it was set to the error current.

· Measurement bugfix: Only the measurement values of the previous measurement interval are averaged, even if not all of the single measurements were successful.

· Measurement bugfix: If a measurement failed, the subsequent measurement failed, too.

· Measurement: improved wind quality under bad measurement conditions

· Measurement: Even if one or two directions cannot be measured, wind speed and direction can now be calculated by using the beforehand determined sonic speed.

· New definition / calculation formula of the wind quality value

VENTUS_Release_V27                                                                                   2015

· New UMB test commands for setting the analog outputs

· Minor bugfix in setting the analog outputs

· Calculation of the sonic speed

VENTUS_Release_V26                                                                                   2015

· Problem fixed: Older wind modules had problems when working with measuring rate 250ms

· Compatibility to wind turbines in china (again)

· Calculation of temperature every second, even if the measuring rate of wind is 250ms

VENTUS_Release_V25                                                                                   2015
