components; a calibration interface and a download interface.
Figure 6 — Service port
The calibration interface serves the calibration, conguration and diagnostics of the EFAS tachograph. The download interface
is used to download the data stored in mass memory or on the inserted driver smart-card. As a special aspect of the EFAS device,
the download interface supports conguration and diagnostic services. This requires the use of the EFAS Service Tool.
