My blank marine switch panel in on CAN2 along with my ADU and PMU  
My Emu black is on CAN1

I want to use 1 of my buttons on my switch panel to switch a map switch table on my black.

Is this easy? How do i do it?

I’ve done this by sending a CAN message from the ADU or PMU to EMU, since one of those must share both CAN networks?

Hi AWMotorworks

have you got a screenshot of what you done, is your can network the same as mine where ADU and PMU are on the same network?

I don’t have to hand right now, but yeah I do PMU & ADU on same network

CAN export from ADU or PMU, channel as keys you want, then can import on EMU (tools, user defined CAN) using CAN SW 1/2/3 etc.
