DDD data format
Data 1 .. Data[Len] are readable with any DDD software.
Attention:
One request can produce more than one Answer.
Mass Memory and Driver Card data are always transmitted in separate files.
Activities which are downloaded in different authentication sessions are transmitted in
separate files.
After transfer of all files an empty frame of the type 'xFF=End of transfer list' is
transmitted.
Example Overview:
Hex: 76 01 16 D3 11 3C 45 F1 0A 2A F0 2E ...
3.3.3
FMS data format (RS232 only)
Data 1..4
Current system clock in milliseconds since ignition on
Data 5..8
Receive time (system clock) of CAN data in milliseconds since
ignition on
Data 9..12
CAN identifier 29 bit
Data 13..Len
CAN Data
Byte order is High Byte First
PikoLoad can store up to 64 different PGNs.
PikoLoad can store normal CAN messages with 8 data byte and multi frame messages up
to 256 bytes.
Example PGN 00F004 (EEC1 = Electronic Engine Controller #1):
Hex: 00 00 12 AA 00 00 12 A1 18 F0 04 29 FF FF FF 00 00 FF FF FF
Example PGN 00FEEC (VI =Vehicle Identification):
Hex: 00 42 91 F0 00 42 90 15 0C FE EC 00 4D 75 6C 74 69 6D 65 73

3.3.4
TCO data format (Ignition on only)
If a value is not available or not used it is sent as FF.
NOTE:
All values are transmitted from the tachograph and are not computed
in any way by PikoSys. The use of the values for calculation of legal
matters is not guaranteed and is on your own risk.
