MBHP CORE V3 & DIN & DOUT boards

[BrianS]

How do the DIN and DOUT boards identify themself with the core board? What I mean, is will the order of the boards not change after each power cycle?

[Phatline]

dont matter - there are IN and OUT Lines, and they are connected thru the PCB... but put the DIN first, since it senses - and therefore it is more "sensible"

All that MIOS cares about is the position of the respective register in the chain. You can also run parallel chains of DIN/DOUT (no mixing in this case) by attaching three IDC plugs on the ribbon that attaches to the Core.
