6 The TRI/TRX File
The TRI or TRI. TRX File is the heart of your data display. All sensors and the associated information
are stored in the TRI file. In principle, every TRX file is a TRI file, but some information is encrypted in
it. Data displays for freely programmable engine ECUs are always delivered with TRI File and data
displays for vehicle-specific protocols are usually delivered with TRX File.
In the following, the structure of a TR I/TRX file is explained. If you open the file with a text editor,
you will find the following structure:
Each line represents a sensor and all metadata associated with the sensor. These 25 metadata are in
columns, separated by semicolons. The decimal separator is a period, not a comma. The figure below
shows a TRI file with two sensors (RPM and CLT) and the metadata associated with the sensors.
Figure 13: TRI File in the text editor
The column position of the 25 metadata is fixed in each row. For example, the Can ID of the
respective sensor is always in the second column.
Table 3 shows the column positions, the designation, thepurpose and peculiarities of the metadata.
The values marked in
blue
are only visible in enhanced mode in DSS (more on this in chapter 9.2.2).
