does not have any information about the CAN message layout from any car maker. However, there are third
party programs such as CANALYZER which you could use to help in this area. This product is not afliated
with Dewetron in any way.
A great invention of Vector corporation is the DBC le. This is essentially a standardized at le which con-
tains the information about a given CAN messaging layout. If you have a DBC le, you may import it right
here and set up all of your channels instantly. Click the IMPORT button under the label DBC library, and then
select the DBC le that you would like to apply.
Scan for messages
Another approach is to checkmark the SCAN button. When you do this, DEWESoft will “listen” on this bus
and identify all of the CAN messages that are coming across, and create messages for them here. DEW-
ESoft will show you how many messages it has found above the SCAN button.
- SCAN can only nd messages that appear during the time the system is scanning. Not all CAN messages are
coming across the bus all the time! Some messages only report errors, for example, so you might have to scan
for days or weeks to see them all this way. Yet other messages will only appear based on a specic query, and
will thus never appear unless you cause them to report on the bus.
- SCAN can only nd messages; it cannot identify the channels within the messages
Of course, since each message might contain any number of channels, starting at various bits and running
any bit length, and with any scaling factors, it is still impossible to know just from the messages, what the
bits represent, but it gives you a starting point. As mentioned, the easiest way is by importing a DBC le,
which contains everything already.
But if you need to congure channels manually, the procedure is quite simple.
Conguring message and channels manually
You can add messages manually by clicking the Message + button (or using SCAN as mentioned above).
To congure the channels contained within a message, click the SETUP button for a message, and the CAN
CHANNEL SETUP box will open:
