IX. Recording Data and Diagnostics of the Engine Interface
The Device allows data to be recorded form the engine network to the MicroSD card for the purpose
of diagnostics and configuration.
Turn the engine ignition off. Create a file called YDEG.TXT with the following line included:
ENGINE_LOG=ON
Note that the given configuration is not saved in the non-volatile memory and will stop its action after
the card is removed or when the NMEA 2000 network is powered off.
Insert the MicroSD card into the Device and turn on the engine ignition. The Device will start recording
data to the MicroSD card and create a file in the root folder with the name YDEGxxx.CAN, where
xxx – is a file number. The Device starts recording to a new file each time the power to the engine network
is turned on.
When the ignition is turned off (power in the engine network), the Device closes
the file. Turn off the ignition and wait for the status of the engine network to change — to be displayed
by a red signal by the LED (see VII.1). After this, the memory card can be safely removed from the Device.
To view, convert or export .CAN files, you may use the free CAN Log Viewer program, which works
on Microsoft Windows, Mac OS X and Linux:

The file format is open and described in the CAN Log Viewer documentation. To analyze data,
protocol knowledge is required. BRP CAN is a proprietary protocol, Volvo Penta EVC protocol
is a proprietary extension of J1939 protocol. J1939 protocol documentation can be obtained
from SAE (
