This track and wiring was freshly installed as a lab for this project. In any case, it seems the detection isn’t initiated by the sensor, the Command node is polling it multiple times a second and I think the (I guess I’d call them drivers) NCE system choices in preferences have been updated for the SB5, I was using the SB3 settings previously per NCE’s instructions. The SB5 choice is working now, we’ll see when I park a bunch of lit passenger coaches all over the layout.

What if this is a hardware/wiring problem? I get the notion that you're convinced
this is a software problem. Perhaps. But you arent checking the output of
the BD20's just in case. Do they stay activated as long as the locos are in the detection block?
A cheap volt meter would give you some answers. You could also wire a LED to the
the BD20 output as explained in the BD20 User's Guide. That should stay lit when the
block is occupied.

They are BD20’s with a common ground using inputs 1-4. Four having the same
result doesn’t seem to be a hardware issue. I was trying to Reach NCE today
but they’re website is mostly down. I’m getting a flash on the LED’s on the
AIU that correspond with the JMRI sensor display. But only when the trains
cross the block gaps.
In case it could be a voltage issue (I don’t have a voltmeter handy.), I
swapped out one power lead from 18Ga to 22Ga wire and got a third loop
around the BD20’s coil. It had no impact on the issue. I think I’ll need
a software solution to the problem. Maybe using a memory variable when it
clicks on that resets when it clicks off.
