USB to CAN, ADU and EMU must be connected to CAN1

CanKB, connect it to CAN2 so you dont need to change kb can speed with light client. If you need kb buttons to EMU, you can forward those messages to CAN1

You can enable CAN2 resistor in ADU settings

Best practice is always use daisy chaining with both ends terminated.

I have a similar Situation with the switchboard. I tried a couple of things forwarding a channel to the PMU.  
My switchboard is connected to ADU via CAN2. EMU, ADU,PMU are connected to CAN1.

I simply like to add a switchboard button in an existing pmu function to conttoll a fan. But I cant see the switchboardbutton from the PMU. Only the ADU buttons.

I also tried to create a function in the ADU an exported it to the PMU, hoping the PMU will get the message from the switchboard.

But wenn I read the upper description I guess I overcomplicating and its much easier.
