Trying to lay out and understand interaction between connections of each screen's serial ports. There are four serial in/out for each screen as I understand. Can each screen have different connected I/O devices and share information through the network? I assume this must be so since there are more devices than inputs, and should certain devices be connected to only specific screens ( adsb to map screen not pilot screen for example, or vpx to pilot screen and not map screen)? Or do shared serial lines simply ignore other info and only respond to pertinent data? Please clarify.
