Tachograph Download Key

In Europe you are legally obliged to read digital tachograph data within a specified period. The driver card should be read once every 28 days, and the internal/mass memory should be read once every 90 days (the exception to this is Ireland where the driver card should be read every 21 days). You must download the data and archive it for 12 months in accordance with the retention obligation. There are various ways to read a tachograph, including by using a download key.

What is a Download Key?

A download key is a device with which you can manually read the data, the so-called .ddd files, from a digital tachograph (download). It is therefore necessary to go to the vehicle to read the data. Reading the driver card is often also possible with the same download key, but in some cases a separate card reader is used for this. The download key has a special output to connect it to the tachograph.

The download key essentially copies the data from the internal (mass) memory of the tachograph as well as the data from the driver cards that are found on the tachograph. From the key, the data can be stored via USB directly on a computer or on an integrated SD card. Each tachograph manufacturer has its own download key solution. We will deal with three of them below.

Always check whether the download key can also read the data from the smart tachograph.

Please note: with a Download Key you do not automatically meet the legal requirements! In addition to reading and archiving your tachograph data, you also have to check all data for completeness and violations. A Download Key does not do this! You still have to analyse all data yourself.

Alternative to the Download Key

The alternative to the download key is the Remote Tacho Download (RTD). This makes it possible to read the tachograph and driver files automatically and remotely. The download key is then unnecessary. The price for the RTD depends on the number of vehicles, request a quote.

Tachograph fines
Also note that if you wait too long to read the data, you will not only risk a fine of £2500 per violation per tachograph, but there is also a risk that old data will be overwritten by new data in the event that the storage limit of the internal memory has been reached.

Avoid fines with an automatic tacho download
The fines are rather high and abuse is strictly monitored. So it is very important to take the digital tachograph and driver card seriously. Since FleetGO takes care of reading both the mass memory and the driver card, you no longer have to worry about this. The two-year retention obligation is also fully covered by FleetGO.

Types of Download Keys

There are two types of commercial Download Keys: a. The manufacturer-specific type – each manufacturer has its own download key – and the manufacturer-independent type. You copy the .ddd files onto the key, so that they are then stored in a safe place, available for analysis and/or monitoring.

All keys work like a USB stick. You connect the key to the tachograph via a standard serial 6-PIN interface, and you can further process the data via a USB output. We will deal with several types of download keys here.
