To import a database, navigate to the System view and select the Databases menu option. Click Import. An Import database file dialog shows.
Select from the three File types: .dbc (Vector CAN database file), .sdbx (HBM sensor database) or .txt (eDAQ CAN database file).
Click Browse to select a file to import from a local directory or external device.
For CAN .dbc files only, click the checkbox to Append message names to signal names. This option appends a double colon (::) or an underscore (_) to the signal name at import, followed by the message name. The double colon is the default. However, the underscore may be preferred for SIE data files in some analysis software. Select the double colon or underscore in System preferences > System > Databases.
Duplicate signal names are made unique by appending a pound sign (#) and a sequential number.
Click Import in the lower right corner of the dialog to download a file to the data processor.
Vector CAN database files (.dbc)
Browse for and import the desired .dbc database file. Once imported, the new database appears in the databases list. Select the file from the list to display the CAN channels.
NOTE
If the system encounters a CAN signal that is not supported (or appears invalid for some reason), the system will reject that specific CAN signal and generate a warning in the Log file. The system will also automatically assign Min and Max parameter values if these are not defined in the DBC file.
For CAN .dbc files only, there is an option to prepend CAN Message names to CAN signal names to generate the composite CAN channel name. This option uses either a double colon (::) or an underscore (_) as a delimiter between the Message and Signal names. The delimiter used is based on the delimiter option defined in System preferences > System > Databases. The double colon is the recommended option. However, the underscore may be preferred for SIE data files in some analysis software (e.g., Catman).
NOTE
If the option to append Message names to Signal names is not used, duplicate Signal names are automatically made unique when importing by appending the string “_duplicate_” and a sequential number.
For CAN .dbc files that include CCP signals, there is an option to import an associated seed and key (.skb) file.
NOTE
The seed and key file name is currently not shown in the user interface.
Click Import in the lower right corner of the dialog to download a file to the data processor.
eDAQ CAN database files (.txt)
The system supports legacy eDAQ CAN databases in a .txt format. eDAQ CAN database channel sets cannot be edited or exported. When imported, these are converted to the internal database format that is used for Vector CAN databases.
Browse for and import the desired .txt database file. Once imported, the new database appears in the databases list. Select the file from the list to display the CAN channels.
NOTE
The eDAQ CAN databases are currently supported only by the eDAQXR, eDAQXR-lite and CX23-R CAN interfaces. They are not supported by the MX471B-R or MX840B-R CAN interfaces.
HBM sensor database files (.sdbx)
Browse for and import the desired .sdbx database file. For information on converting standard .sdb files to compatible .sdbx files, see HBM sensor databases.
Once imported, the new database appears in the databases list. Select the file from the list to display an overview of the database and the number of supported and unsupported sensors.
NOTE
Future data processor firmware versions may support more sensors. The HBM sensor database does not need to be re-imported to use newly supported sensors.
