M800 CAN bus protocol

[GMS Racing]

Hi,

I have an M800 in my MINI JCW and want to connect it to a Race Technology (RT) data logger and display that I have. The RT kit can accept a CAN input and is configurable, so I need to know the details of the Motec CAN bus interface.

The RT program is fully configurable and I require the following information.

Device name e.g. RPM
CAN ID length - 11 or 29 bits
CAN ID
Filter location - None, 1 to Byte 8
Filter Value
Start bit - 0 to 63
Length bits - 1 to 32
Value type - Signed /Unsigned / Float (single)
Byte order - Intel Standard / Interl Seg / Motorola Forw LSB / Motorola Forw MSB / Motorola Seq / Motorola backward
Scale factor
Offset
Exponent (for time only)

Also, I need to know the CAN baud rate - 1Mbit / 500Kbit / 250Kbit / etc.

did you check the race technology Knowledge base?

that answers your question

what htis also means is that RACE TECHNOLOGIES recommends you use RS232 instead of CANbus.

figgie,

Thanks for your reply, yes I have checked the RT knowledge base but I want to get the CAN bus option working as it opens up a lot more projects for me in the future.
