New to CANBus, can it do what I want it to do?

[QE1984]

We have a new Thunder ECU, AiM PDM32, Blink Marine CAN keypad and a 3rd party CAN device. Wiring everything together now, and have the BM keypad occupying the AiM CAN2, the Thunder CAN1 is connected to AiM CAN1 (ECU stream).

What we want to do is send data channels from a 3rd party CAN device to the PDM. From what I understand, the Blink Marine Keypad takes over the entire CAN2 on the PDM, at least when using their plug and play software interface on RS3. And CAN0 is only for AiM branded units. 

So the question is, are we able to receive channels on the Thunder CAN2 and transmit those channels on the Thunder CAN1? Or can we add additional CAN devices to CAN1? 

Please help me understand what my options are before I make any final decisions. 

Thanks

Yes you can set up a custom "ECU stream" for CAN 1 in RS3 to receive both the ecu and other device data together. I can give you a hand when you need it.

The only requirement is all devices on the same bus must operate at the same bit rate and they all must use different ID's.

Thank you Adamw. Having the devices be the same bit rate won't be a problem I'll reach back out when we need a hand. 

Thanks.

Hi I have wired my   Can hi low and daisy chained so my pdm-fury-lambda-blink key pad  are all on 1 bus (can 2)  should I separate the key pad and put that on can two  and the rest on can 1 ? I have followed the protocol instructions but I don’t appear to be getting any communication  I have put a termination 120 ohm resistor between the keypad  can H+L 

again still nothing 

thanks

They are fine all on the same bus as long as you have them all set to the same bitrate.
