Make your DLK Pro Download Key S compatible with the DTCO 4.1
VDO is making a free update available to make your existing DLK Pro S compatible with the new Smart Tachograph Version 2 and 3rd generation driver cards.
Click on the 'Update' icon and choose the "DLK Pro Family Update" on the new page that opens.
Additionally, you can make sure your DLK Pro (the predecessor of the DLK Pro S) is compatible with the DTCO 4.1. To do this you must first buy the DTCO 4.0 License Card and activate it on the DLK Pro, making it suitable for reading files from the smart tachographs, before following the same process as the DLK Pro S.
