Butterfly display update through PowerFlarm in 2 seater (English)

If you have a two seater installation, you have to update only one display a time. You have to hold the knob down on the display which you want to update, while switching PFs power on. It is also necessary, that the display, which you want to update, can receive and send data from/to the PF, which means if you use a Y-Adapter with a display-TX switch, you have to set the switch, that the display which you want to update can send data to the PF. If you have connected the two displays to a PF cores' two different ports, it should work.
