The device establishes a connection between the digital tachograph and the TIS-Web® RTM service. The tachograph and driver card are authenticated using the company card. Then, this data is transferred from the digital tachograph for intermediate storage on the DLD®. The DLD® Wide Range II transmits the encrypted data using GPRS to your office PC via the TIS-Web® RTM server. As a TIS-Web® data management customer, you receive the data directly on the TIS-Web® data management server via a secure Internet connection (https) for archiving and evaluation.
