The Logger Settings window is accessed by choosing the Settings... button on the Models D and E Logger Main Window. It, therefore, only applies to Model D and E loggers.

Models D & E Logger Settings Window

With the Settings Window you can set up information in the logger which will be used for any traces recorded in the future until the settings are changed again.

The sample interval setting affects the actual data stored in the trace. The remaining data is simply stored with the trace. The user number and declaration information is protected by the logger's security code mechanism whereas the comment text is simple annotation which can be modified by the user after upload in some software supplied by EW Avionics (though not in EW Windows Uploader) and so is not covered by the security code.

The User Number should be any number in the range 1 to 9999. It can be used to identify traces. Typically it is set to the glider's competition number if that is all-numeric.

The Sample Interval is the number of seconds between samples of pressure altitude and GPS position in normal operation during the recording of a trace.

The Comment text is user annotation which can be used to describe a trace. There are limits on the number of characters in each line and the number of lines as noted below the edit box.

Accented letters and other non-US-ASCII characters can be entered but note that they may be modified by a character set conversion before download to the logger and its inverse when the comment text is uploaded back again and that they will be transformed to "equivalent" characters when written to logbook records in .IGC file (as .IGC files are only allowed to contain a very limited set of characters). This second transformation is documented at EW Avionics IGC File Format - Character Mappings. Typically, this means that accented letters are transformed to their non-accented equivalents.

The Declaration information can be set to indicate a flight being declared for badge and record purposes. In addition to the information entered here, the logger will record the date and time that the declaration was downloaded relative to its own clock thus allowing the last declaration made to be determined.

Important Note: The declaration is downloaded even if it has not changed. Therefore, if the OK button is pressed to download non-declaration information (such as a new sample interval) or even for no change at all a new declaration will be made. This declaration will cancel any previous declaration made on paper or on this or another logger. To avoid cancelling a declaration made separately from this logger make sure that all of the declaration fields are clear before downloading the settings. The only way to avoid cancelling the declaration in this logger is to not download the settings, but replacing an old declaration with a new one which is the same is usually not a problem.

Flight Date is the date on which the declared flight is to be made. Note the specific format in which it must be entered.

The declared Task can be specified using either the names of the turn points or their latitudes and longitudes or both. TP names can be upto six characters in length. The same character set conversion noted for comment text is also applied to the TP name. In addition, the characters are transformed to the IGC subset before download to the logger.

EW Windows Uploader does not make use of a TP database so lat/longs have to be entered manually. They must be entered in exactly the format specified in the text below the lat/long column though some minor variations are allowed: the letter 'd' can be entered as a degree symbol () and the fraction of minutes can be replaced by two digit seconds (e.g., N51d36'30" W000d48'01") though decimal minutes are always displayed.

The remaining fields allow the entry of additional information required for declarations. Eight characters may be used in each of the glider information fields, twelve in the others. The same character set rules as for TP names apply.

The OK button causes the settings to be sent to the logger then the logger main window to be displayed. Cancel discards the settings and returns directly to the Logger Main Window.
