In its standard case, CANgineII_BT only measures 92x44x24 mm3 and
contains a modern 32 bit microcontroller, which is internal clocked at 72 MHz.
The Arm controller offers enough resources even for future firmware
extensions. The supply voltage is 7…32 V, the operating temperature
range is -40…80°C.
CANgineII_BT supports all messages defined in all standards up to
version 3. If the vehicle is equipped with one of the newer versions,
the connection of the D8 info serial link is generally not necessary as
information about the inserted driver cards is provided by the newer FMS
standards. This simplifies cabling.
D8 Info Link of the DTCO
digital tachograph (DTCO) features a serial output on ist rear panel,
where the driver’s card data and some vehicle operational data are
transmitted cyclically. Unfortunately the data format is not specified
in the EU regulation paper and therfore the tachograph manufactures use
different data formats.In its actual revision CANgineII supports the VDO
and Stoneridge formats, other tachographs will be added on request.
Remote Download function via FMS CAN has been published at the end of
2008. CANgineII_BT grants access to this helpful feature without having
to learn the related CAN protocol. A special serial protocol provides
access to authentication and data download. On the telematics host side
we provide Run-Time API for Windows and Android which realizes most of
the programming tasks and facilitates building the Remote Download
application. Both API offers the functions to open a session, to realize
the authentication process and to download the tachograph’s and the
driver card’s data. To further facilitate the programming work the
example application which is delivered with CANgineII_BT is available as
a source code package.
If the vehicle doesn’t yet support the Remote Download feature on the
FMS CAN, CANgineII_BT can be connected to the rear panel of the digital
tachograph. Using a configuration command the specific link for Remote
Download can be defined.
CANgineII_BT can be parameterised by a lot of useful parameters and in
this way be adapted to nearly any special demands of a given telematic
application. The telematics host is not bound to read all the real time
variables. With the help of parameterising commands the variables are
selectable by masks as well as the time or distance period of the output
The example software is delivered for Windows and Android. The
software shows all functions of the CANgineII_BT including the Remote
Download function. A terminal window is used for direct communication to
the device. In this window the operational parameters are set and the
data output can be watched. With the settings basic communication
parameters can be adjusted. The Remote Download tab is used to set the
target directory for download data, to authenticate the download and to
download the data sets from the tachograph or driver cards to the
With the help of the Remote Download function companies are able to
fulfil the compulsory archiving without manual intervention of the
downloaded by the Remote Download Function contains a digital signature as requested by the law in most European countries.
Output of Real Time Values
The cyclic output of real-time values can be done in two different
formats. The so called debug format is used for the initial operation
procedure and for monitoring after modification of parameterising. In
normal operation mode when data is transmitted to the telematics host a
compressed format is used, where no leading text and no physical units
are output. In this format, the values are separated by semicolons and
can be prefixed by an optional index value.
