The Downloadkey can be formatted as needed as a USB (pendrive) on your computer.
It has on the one hand an RS-232 output that is compatible with all digital tachographs and on the other hand a USB output, which facilitates access to obtain data via a computer. It does not require an external power source. The LEDs indicate the current status of the discharges. With the configuration software it is possible to individually configure the Downloadkey.
Updates to both the program and the download device are free of charge. We also offer full technical support in using and understanding both the download device and the included software.
