4.4 Data download
Driver, vehicle, and calibration data can be downloaded (copied)
over the download interface from the DTCO 1381 data memory and
from an inserted driver card.
The legislators have planned a data download for the following
cases:
• Street and operational controls
•Sale of the vehicle
• Decommissioning of the vehicle
• Replacement of a defective DTCO 1381
A download can be executed after positive authentication of a valid
company, workshop, or control card. The respective access rights are
regulated in CR (EEC) 3281/85, annex I B, see next page.
The downloading of data will not alter or delete the data in the
memory of the DTCO 1381 and on a tachograph card.
Before the data is downloaded, the DTCO 1381 will attach a digital
signature (identification) to the data being downloaded.
With this signature, the data can be assigned to the EC recording
equipment and permit checking of the data’s completeness and
authenticity.
