Pixhawk 4/Ardurover UART/RS232

Hi there,

I’m trying to get a EPOS4 Compact 50/15 CAN (520886) with my pixhawk 4/Ardurover running.
the EPOS4 controller has a UART/RS232 Interface.
I haven’t found any hint, that this is even possible.
Do you know if I need to use a converter or can I connect to the controller directly?
