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.

This doesnt seem to be a JMRI issue. The block detector will stay active as
long as
something that draws current (locos, conducting wheel sets, etc) is within
the block.
The detector output should remain "high" (voltage-wise) when there is no
block activity.
When the block becomes occupied, the detector output will go "low." You can
check
this with a volt meter. Are you using BD20's or DBD22's. Ive gotten both to
work well
with an AIU and JMRI.

Subject: [jmriusers] JMRI - NCE Block Detection
Hi All
I just spent a couple of days going through Robert Bucklew's Quaker Valley
Lines Panel Pro tutorial (Very well done) parts one and two. After sticking
to the tutorial I paused at the end of Part 2 and figured I'd repeat part 1
and part 2 on a portion of my Living Room Layout. Then I ran into a block
detection issue, the block sensors seem to flash on when a train enters and
again when it exits, but isn't persistent so I've been unable to mark the
block occupied on the panel.
My Layout is NCE SB5, via the USB Interface, My sensors are BD20's connected
to an AUI01. My firmware is of the proper version (7.3.3) and my sensors are
being read from the AUI by JMRI. The JMRI is Version 3.6-r24520 running on
Centos 6.5 and Java 1.7 (60).
The USB interface is CAB 8
The AUI interface is CAB9 (per the SB5 Documentation)
The indications are that the sensors are triggering on entry and exit of a
block, each train passage the correct block transitions are lighting up. Is
this proper behavior for these devices? If yes how do I capture the entry
and exit of a train from each block? This will necessarily need to be
direction agnostic.
I've attached the Panel XML files as a zip archive so virus scanners won't
delete the XML and will be greatful for your advice.
Thanks in advance.
