CANBUS Sensor

Postby killerbee on Sat Mar 18, 2017 1:42 am

I am considering using a Bosch Motorsports Acceleration Sensor (MM5.10). The product datasheet is attached. It appears that there is an option for a 500 kb/s or 1mb/sec CANBUS speed. What speed is most appropriate ? I am going to be using this sensor in an SDL3 and C185 installation.

An associated question is there a CAN template that is available for this sensor ?

Thank You.

Use the 1Mb/s version, as many MoTeC devices can only communicate at 1 Mb/s. The SDL3 and C185 do have configurable CAN bus speed, so you could run one CAN bus at 500 Kb/s if you wanted.

Here are the templates I have for this device on a C185.

I have just had a quick look at those templates and they are not correct for that sensor.

All of the signals on the MM5.10 are offset by 0x8000 so there needs to be an 'adder' set for each of the signals. The Multiplier and Divisor are also not correct as the Base Resolution and units haven't been taken into account.

I have attached some templates that will also work with your SDL3, you can use the import feature in the comms setup to convert them to use with the latest version of C185 Manager.

Thanks Adrian, I got that from a customer -- I've sent him your updated version.
