Driver2 Working State
Driver 2 Working State indicates the state of work of driver 2,
i.e. activity currently selected on the recording unit for the co-driver,
and shall provide:
data length: 1 byte
LSB 000 - break/Rest
LSB 001 - availability
LSB 010 - work
LSB 011-101 - reserved
D1I
Driver1 Identification
Driver 1 Identification shall be used to obtain the driver 1 identity from a driver card
inserted in the recording unit, and contain three (3) bytes for the issuing member state of
the driver card, and sixteen (16) bytes for the card number, see tachograph regulation,
appendix 1: Nation Alpha and Card Number format), and shall provide:
data length: 19 bytes ASCII
byte: 1 - 3 - issuing member state
byte: 4 - 19 - card number
D1CDT
Driver1 Continuous Driving Time
Driver 1 Continuous Driving Time shall be computed as the current accumulated driving
times of a particular driver, since the end of his last availability or break/rest or unknown
period of forty five (45) minutes or more. This period may be splitted in several periods of
15 minutes or more.
This parameter shall provide:
data length: 2 byte
resolution:
1 min/bit gain, 0 min offset
operating range:
0 to 64255
The computations involved take into account, as needed, past activities stored on the
driver card. When the driver has not inserted his card, the computations involved are
based on the data memory recordings related to the current period where no card was
inserted and related to the relevant slot. For more details see tachograph regulation.
This way of computing the continuous driving time and the cumulative break time serves
into the recording equipment for computing the continuous driving time warning. It does
not prejudge the legal interpretation to be made of these times.
Unknown periods correspond to periods where the driver card was not inserted in a
recording equipment and for which no manual entry of driver activities was made.
