Summary   Menu Items   Field Descriptions

Summary The poll data screen reads information from the vehicle (via the OBD2 converter hardware), and displays a summary table of information gathered. The actual data points to be gathered are specified via the polling designer screen. You can control how many data points are collected and how often the screen is updated by using the max poll loop(s) and screen refresh fields. Logging Data Polling can be interrupted and restarted without starting destroying previously logged data. By default, the summary table and logging data is not cleared when polling is restarted. To reset data and logging, use ctrl-R or pull-down menus Edit, Reset Data. Data will be lost when you exit the program. To preserve logging and summary information, save the data before exiting the polling screen (pulldown menu File, Save Log Data), then reload data when ready to continue (pulldown menu File, Load Log Data). Please note that reloading the log data will overwrite any polling designer changes that may have been performed since the log data was saved. (The Load Log Data function is currently NOT implemented, this will be added as soon as possible) Exporting Logged Data Logged data can be exported into a file to make your data available to an external program, such as a spreadsheet, a text editor, or advanced charting software. All values are converted into specified units, and a header line describing the data is generated. To facilitate import into a spreadsheet, the data is organized such that data is grouped into columns, and rows represent time. Currently, time is represented as the number of seconds since logging was first started. Since not every data element is collected simultaneously, the greatest timestamp for the row is used. Currently, rows are generated only when necessary ie. the current row will continue to be used until one of the columns has multiple data values, forcing a new row. If a data element is been set in the designer to be collected infrequently, it will be represented as blank (not a zero or a repeated value) in the row for which it has no collected sample.

Field Descriptions

• Screen Refresh (secs) - specifies how often the summary will be updated. The idea is to allow the vehicle polling to occur as fast as possible, without the screen painting process slowing it down. It is also useful if the operator wants to be able to read current values easily, and to eliminate cursor flicker and blur.
• Max Poll Loops - specifies the maximum number of poll loops to execute before stopping. This is useful if the operator wants to see a predetermined number of data points, or to limit the amount of PC memory involved in logging data
• Start Polling -
• Back to Main Menu -
• Summary Table
  The summary table is updated as often as defined by the screen refresh field.
  Events have additional information via color code as follows:
  • grey background shows that the current value is equal to the minimum and maximum values (the data has never changed)
  • yellow background indicates that a polling eror has occured during the last screen update interval
  • blue text indicates a change in the maximum or minimum values
