DawnEdit™ is the database editor used to build the database for you vehicle and configure the DAWN Mini Loggers. DawnEdit will determine the parameters that are actually on your vehicle and builds a database for each vehicle model, so you only need to select the parameters of interest from a table.
DAWN comes standard with a generic OBD-II database which defines almost 100 parameters according to the SAE J1979 standard; 40 being available on a typical car. *Click image to enlarge*
The SAE J1939 standard defines almost 2000 parameters; typically 150 to 400 parameters are available on a heavy duty truck. *Click image to enlarge*
After selecting the parameters to acquire and the sample rate, you would then create a configuration file and transfer it to the logger’s microSD card.
DAWN imports proprietary DBC files for normal messages and CSV files or Access databases for Enhanced OBD (EOBD) and custom messages. HEM Data provides EOBD databases for various manufacturers as an option.
DawnEdit converts the message files stored on the logger to a CSV file containing scaled engineering parameters. Another option is to transfer message files to a website and have the website convert the message files to scaled, engineering parameters. Click here for website details.
Options include:
- appending trip files together or keeping them separate
- time can be shown as either relative time from the start of a trip or the absolute time of day
- calculating fuel economy and idle time
