The Digidown is supplied with a USB lead for connection to a PC. When connected to a PC the Digidown appears as a mass storage device to the computer.
Files downloaded by the Digidown are in the format specified in EU regulation 3821/85 Annex 1B Appendix 7 and should be readable by any drivers’ hours software package which is capable of handling data from digital tachographs.
The Lisle Design Digidown has three buttons:
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.
 
For fleet operators, ‘latest’ downloads all data recorded by the VU since the previous download. For drivers’ hours enforcement purposes, ‘latest’ downloads data relating to the last 8 or 28 days. For accident analysis, ‘latest’ 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.
