Hello,

I am setting up a car with two PMU units (24dl + 16dl) + a 3x5 rotary keypad.

My question is: In the PMU software do i have to create the same keypad for both PMU’s?

As I have outputs from both PMUs, I need to control them with the keypad.

Thank you in advance.

In the primary PMU add a CANbus Keyboard and setup the buttons as you require.

In the Keyboard object at the bottom you’ll see ‘Export state and buttons to CAN’. Use this to send the buttons to the second, third etc… PMU.

I’ll add, if you create 2 keyboard objects, one in both PMU projects. This could create a race condition where the PMU’s are out of sync.
