3.2 Digital recording equipment
Digital recording equipment includes certain devices that are suitable for the fully or partly automatic display, recording and
storage of details concerning a vehicle’s journey and concerning certain working times of the driver.
Recording equipment consists of the tachograph, connection cables and a motion sensor (pulse generator) as well as a DSRC
facility, a GNSS receiver and an optional ITS interface.
The driver’s activity-related data is stored on the driver smart-card. Vehicle-related data including speed, distance driven, vehicle
mileage etc. is saved to the recording equipment’s mass memory.
The following data is stored to mass memory:
y Equipment identication data (Vehicle unit identication data, Motion sensor identication data)
y Keys and certicates
y Driver or workshop card insertion and withdrawal data
y Driver activity data
y Places and positions where daily work periods begin, end, and/or where 3 hours’ continuous driving time is reached
y Odometer data
y Detailed speed data
y Events data
y Faults data
y Calibration data
y Time adjustment data
y Control activity data (relevant to the 20 most recent control activities)
y Company locks data (relevant to the 255 most recent company locks)
y Download activity data (relevant to the last data memory downloading to external media while in company or in cali-
bration mode)
y Specic conditions data
y Tachograph card data
3.2.1 Provisions for drivers and employers
The use of analogue, digital or smart tachographs is governed by EC Regulation 3821/85 Appendix I B and 3820/85 as well as
by implementing Regulation (EU) 2016/799 and implementing Regulation (EU) 2018/502. This regulation imposes a number

In the event of disruptions to the recording equipment, e.g. when the internal clock shows a signicant time dierence, the
recording equipment must be checked immediately by an authorized workshop.
If data required for recording is changed on the vehicle, e.g. tire circumference, motion sensor or the ocial registration number,
these changes must be entered in the smart tachograph by an authorized workshop.
3.3 Description of the tachograph smart-cards
Tachograph smart-cards are electronic smart-cards that are used to identify the user to the smart tachograph and on which
certain data is stored for retrieval.
