Get On Board with OBD II
The OBD II (On Board Diagnostic II) is standardized vehicle
interface which must be implemented in each vehicle sold in
the UsA; and California law requires a standard interface for
measuring vehicle exhaust. Parameters like vehicle speed,
engine RPM, throttle position and temperatures can be read out
of any vehicle which has the OBD II interface. The 101 simply
requires a cable to connect the OBD II port to one of our CAN
interfaces.
J1939 Truck and Bus protocol
J1939 is a standardized truck interface working on the CAN
bus. Virtually all trucks comply with this standard. simply check
the J1939 on-screen box for either of the DEWE-101’s CAN
ports. Note - the older J1587 is also supported!.
DBC File Import support
You can set up your CAN parameters very easily within
DEWEsoft - create the arbitration IDs that you need, and
then define the messages within each ID. Or, if you have
a DBC file which contains a list of IDs and messages in a
standardized format, you can directly open it from within
DEWEsoft!
There is also a sCAN checkbox that will “listen” to the
bus and create IDs for all channels which are sending
messages. But you need to know the message parameters
like scaling, bit range, name, etc., because these are not
broadcast via the CAN interface.
Setting up your CAN channels can be done manually - or via SCAN, or via DBC file import. In the screen shot above you can see the SETUP
dialog for Arb ID I2D is open, and that this ID contains three messages - Satellites, Time, and Latitude. Messages are color coded for your
convenience. Each one can be scaled and configured freely.
