Hi,  
Still pretty new to programming/setup so apologies in advance.

I have an ECUmaster CAN steering wheel panel setup in a PMU24, all working as it should.

I would like to use rotary knob 4 to cycle dash pages in the ADU and switch 5 as the user defined lap button.

When I’ve done similar before with a CAN keypad I’ve done the export keypad state / save file thing.

Do I just save the CANX file from the CAN switchboard in the PMU and use that in the ADU also? I guess that is the same process as the keypad really and seems logical?

If anyone has a screenshot of the actual setup, that would be handy also and of course can be used for future projects or if/when people search a similar topic.

Thanks for your time

Just import rotary4 from CANx → CanSwitchBoard V3 → c\_csb\_rotary4, and then assign it as the page selector in the Configuration tab. Do the same for switch5.
