The digital tachograph continuously stores data in the internal memory and driver’s card. The internal memory stores data from the last 365 days of the vehicle. Data stored on the driver’s pass and data contained in the internal memory must be downloaded periodically (as mentioned above). This data must be stored in DDD files for inspection by public authorities.
With a Squarell FLEX or SOLID (which has loaded the RTD profile), it is possible to perform the required downloads via the Remote Tachograph Download without having to go to the vehicle.
With the Squarell RTD implementation, the transport company can put the company card in a card reader at the back office. The card reader is connected to the tachograph via the telematic service provider’s modem together with the FLEX or SOLID. Now, the (inserted) driver card and the vehicle data in the internal memory can be read. All data of the tachograph can be merged into DDD files to be saved and stored.
