Frequently Asked Questions
1.
Q:
What should I do, if my company card does not accept the APDU packet from a server?
A:
Our APDU packet is encoded and you must use a
Tacho-library 1.1
library to decode it. Please ask our
technical support for the tachograph communication user manual.
2.
Q:
What should I do, if my tachograph does not authorize?
A:
Please check if you have some other third-party devices connected to the tachograph. They might be
asking for data packets at the same time while you are trying to authorize.
3.
Q:
Why are the driver activity fields in records empty?
A:
The driver could have locked the tachograph with a card from another company and you are trying to
download the information with your card.
4.
Q:
What should I do, if my downloaded file is corrupted?
A:
If in your downloaded data period there is a day with a bad file signature, you can get a corrupted file.
You should read the same data period file from the tachograph front via a special device and check your
file validity with an authorized third-party software. If the entire file is invalid, then there is a problem with
your tachograph.
5.
Q:
What should I do if there are corrupted tachograph data fields?
A:
Please check for the following error in the .DDD file
Events and fault
block,
Events data
part:
Vehicle
unit related security breach attempt events
–
Stored user data integrity error
. If you have one, please take
your tachograph to a tachograph service for a VU (Vehicle Unit) investigation.
6.
Q:
Why is the .DDD file download process unstable?
A:
Please check if your tachograph is connected to the FMS line. If yes, try to connect the tracking device
to the tachograph directly (socket
