Possibility to increase the number of CAN for C187?

[HMeier]

Hello,
i use a C187 display logger. Is there a possibility to increase the number of CAN Inputs to more then 4?

Best regards

Hi,

Are you needing more than 4 separate CAN Buses?

[HMeier]

Hi Stephen,
yes more then 4 seperate CAN buses.
Is there a posibility?

[Stephen Dean]

Not on the current hardware.

What are you doing that requires more than 4 CAN Buses?

[HMeier]

Hi Stephen,
thank you for your fast response.
I have some ECUs that are sending seperate messages with the same IDs. I will fix it with a gateway.

Sounds like compound messaging, which the MoTeC CAN implementations handle easily.

[Stephen Dean]

As David said, This sounds like a situation that can be handled with the current M187 hardware. Do you have a DBC files for the messages that are being sent? or any other information on the massaging that can be shared?

If you look at the PDM Input State receive template in the Communications setup in the Dash Manager, you will see how MoTeC has implemented a receive message using compound messaging from the PDM.

I believe HMeier doesn't have ONE ecu sending multiplexed CAN messages, but instead multiple similar/equal ecus which all use the same IDs for transmitting their data, hence he mentions the gateway...
but I could interpret it wrong as well.

[HMeier]

MikeD is right. Problem is solved via an extra gateway.
Thanks for fast response.

I would like to hear more about an application that has more than 4 ECUs
