With the arrival of digital tachographs according to EU Regulation 3821/85 Annex 1B, there is a requirement to download data from digital tachograph vehicle units (VUs). In order to do this an appropriate piece of equipment must be connected to the download connector on the front of the VU, and then the data within the VU can be transferred (downloaded) to the download equipment.
The download equipment can be:
- A laptop computer with appropriate software
- A palmtop computer with appropriate software
- A unit explicitly designed for the downloading of digital tachograph
data - the Digidown from Lisle Design.
The Lisle Design Digidown has three controls:
- All VU - pressing this causes the Digidown to download all the data stored in the VU.
- Latest VU - pressing this causes the Digidown to download only the latest data within the VU.
- Card - pressing this causes the Digidown to download the data
from the driver card (if any) inserted into the VU.
The control buttons can either have text or symbols on them, as shown above.
For fleet operators, 'Latest VU' typically downloads data recorded by the VU during the previous 2 to 3 months. For drivers' hours enforcement purposes, 'Latest VU' typically downloads data relating to the last 8 or 28 days. For accident analysis, 'Latest VU' perhaps downloads the detailed speed data.
During operation the three LEDs by the buttons indicate the progress of the download activities. The downloaded data is stored in the SD memory card inserted in the Digidown.
After downloading, the downloaded data may be transferred to a permanent store and to any appropriate drivers' hours analysis software package. The data transfer may be carried out by:
- carrying or posting the SD card to the appropriate office and
then reading the data from the card using an SD memory card
reader. A suitable memory card reader is available from Lisle
- connecting the Digidown to a vacant USB port on a suitable computer and then reading the downloaded files in just the same way that files might be read from other memory devices. A suitable USB lead for this purpose is supplied with the Digidown. When connected to a USB port in this way the Digidown appears to the computer as another mass storage device.
Files downloaded by the Digidown are in the precise format specified in
EU regulation 3821/85 Annex 1B Appendix 7 and thus should be readable
by any drivers' hours software package which is otherwise capable of
handling data from digital tachographs.

Digidown Configuration - Digidown File Name Format
What is downloaded when the 'Latest VU' button of a Digidown product is pressed is is configurable.
Each time a Digidown product saves a tachograph data file that file is given a name. The format of this name is not specified in any EU tachograph regulations. However the authorities in France and Spain have defined file name formats which must be used in those countries. Elsewhere there is no specific requirement for any particular name format but there are several commonly used name formats.
