Hello. How are they?

I am working on a project with a MOTEC M84 and I need to link it with Dash Marelli for the CO-DRIVER. I am missing the DBC file to do the job.

Could you send me the file?

THANKS AND REGARDS!

Below is a document that outlines how the CAN messaging from an M84 works. It sends out CAN messages like a serial stream with a header and checksum all on one CAN address.

Also below is a dbc file but because of the data stream format the file doesn't comply with the dbc file spec and won't open in most programs. It is really only useful as a list of channels.

Hello,

Opening this dbc file with Canalyzer gives error message.

Opening it with AIM RaceStudio makes application to crash.

Dis someone face this issue?

Can you open the PDF file? Read the DBC file in a text editor. As stated, it's only useful to get the channel names.

Hello,

Sure, I can open the PDF file. Interest of DBC file is to respect Vector formalism to be able to import file with other system.

If file does not follow formalism, rename it as txt file to avoid mis-understanding

I wouldn't expect any DBC import facility to understand the M84 stream. You need to read and understand the PDF document if you have any hope of implementing support. Without access to being able to write code on whatever platform it is your working with, it's unlikely you can be successful.

AIM already has support for the M84 stream. If your goal is to add other non-M84 can messages (because Aim only support one "protocol" on each CAN bus), you'll never be able to do it with the M84. Best bet today is to use the CAN2 bus (if your logger has that), and put your custom protocol on that CAN bus. Connect CAN1 and CAN2 to the same CAN bus if you wish, that does work.
