Don't quote me on this, but I'm pretty sure they're just "return" terminals for the A and B data circuits, in that they kinda act like Class A circuits on NACS where if there's a break in the wiring somewhere, the ann devices will still function but you'll get a trouble on the panel for an open cir.
So qiestion....do you have to use an additional 24 volts for it to work or can it be connected with the simple 4 wires?
Good work. Keep it up.
What are ARTN and BRTN used for on the ANN-BUS PRI?

I wonder if this will work for a Ms10ud
it does...the MS10UD-7 supports ANN-80
