Does that make my drawing correct or wrong? As Dick has said, a bad idea. The ground wire needs to be parallel to the signal wires and go directly to the AIU ground. To do otherwise invites trouble, ranging from false triggering to voltage spike damage.
The reasons are that:
- Your input connection becomes a loop antenna prone to picking up electrical noise.
- Your earth paths (part of the loop) will likely be carrying other current, with consequent voltage fluctuations, creating nuisance triggering and possible device damage.

Re: Detection in JRMI with NCE Accessories
Hi Dave
Sorry for the delay, been sick. I am confused on your last reply, see below about a ground loop.
My Assy. Bus is power by a separate external power supply, unrelated to my DCC power system.
My GND side of my Assy. Bus is what¡¯s running to my AIU¡¯s GND, along with the GND on my BD20¡¯s and the GND side of my external power for my Switch8 Mk2¡¯s.
The positive + side of my Assy. Bus goes to the other external side of my Switch8 MK2¡¯s.
Since the switches inside the tortoise are isolated, where is the GND Loop supposively happening at?
Thanks for any any input here.

Frank,
Get a 16-18VDC power supply for your PR3. I use an 18VDC 1.1 amp power brick salvaged from an old inkjet printer.? Then get rid of the Power Pax. You won't need it. My PR3 with that 18VDC supply will reliably read/write to any sound decoder I've tried (just about all popular brands except MRC).
HTH,

Get rid of the Power Pax and use a PTB100. The PS14 is enough power though I have a 16 volt on mine.?

I had my Pi's before I got into JMRI. I was just using my DCC system standalone. I got my Pi's (2, 3B and 3B+) to get back into Linux. I installed various HATs. Then I found out about JMRI and tried it with my netbook, notebook (running various versions of Windows and my Mac. Once I figured out the nuts and bolts I put it on a Pi and have had more fun pulling out UP5's (not needed) except for two just in case. I installed JMRI and added to my men because I like a bare desktop.

Re: BLI Paragon 2 and 3 reading
Marc, I played around with audio feedback only on my BLI centipede, which I had already finished reading at that point.
I¡¯m away from my computer for a few days but will report back by next weekend on another BLI on how helpful it is to turn off audio feedback before reading the complete decoder.

Re: SECTIONS TABLE NEW BUG
Hi Dave,
as soon as I hit "update" to the section, and have the message log open, i get a long-winded error.
It also throws up a window with the same error.
I can provide a screenshot, however the first error is:
java.lang.Error: Cannot call invokeAndWait from event dispatcher thread
followed by about 20 others.
most of the errors finish with (unknown source).
If you'd like a sccreen shot, please let me know the best place to send/put that.

Re: Release 4.17.4. Cell phone no longer controls trains
Frank:
As promised... Using my tablet I found a place where I lose signal so I see that the message I see that as "no signal, trying to reconnect" but it also includes your "is WiThrottle running..."? I hadn't read that far just seeing the no signal was enough...
When this happens the signal strength indicator is gone down to no bars... so yes I think there is a signal strength issue. How this coincides with the 4.17.4 update I can't guess...
The WiThrottle pane keeps the throttle listed only dropping it when you tell EngineDriver to shut sown.
Grasping for straws... Was there an Android update? There are reports of Android versions not liking to connect to WiFi if no Web connection is running but if same router as TV and Mac that shouldn't be the problem...
I have no fix I'm afraid...

Re: BLI Paragon 2 and 3 reading
Dave,
Thanks for that explanation.? Yes, I did see a lot of indexed CVs when reading my Loksound Select Micro decoders, just didn't realize that's what I was looking at when doing it.
I'm learning!

Re: BLI Paragon 2 and 3 reading
Sam, thanks for the tip about CV217, but my JMRI decoder definitions for Paragon 2 and 3 steam (I have both) as well as Paragon 2 diesel do not list a CV 217 on the CV pane, unless it's some hidden indexed CV or something like that, in which case I don't know how to access that.
None of the Paragon 2 or 3 technical manuals mention a CV217.
None of the Paragon 2 or 3 technical manuals mention indexed CVs. (If they did, one would hope that they followed NMRA S9.2.2 specification for indexed CVs; pages of CVs in the range CV257 to CV512 inclusive, with CVs 31 & 32 as the index registers to specify which page of CVs CV257 to?CV512 select.)
If the?Paragon 2 or 3 supported indexed CVs, the definition JMRI would know how to access them.
The only mention of CV 217 was in an email on this thread:
Dave in Australia
For your personal information (and off-topic), here is a document I wrote in an attempt to demystify the much-maligned topic of Indexed CVs. (But the Paragon decoders do not support them.) Read on only if you wish.
Indexed CVs
As others have said, indexed CVs are a way to have more CVs than just those available in the range 1-1024 inclusive (a limit set by the DCC packet standards in S9.2.1). Many of these are already reserved for particular purposes.
However the NMRA standards anticipated that need and provided for a way to allow for many more CVs. This is intended to be done by a page indexing system for CVs in the range 257-512 inclusive, allowing for in excess of 16 million CVs.
The NMRA standard S9.2.2 covering Configuration Variables defines the following:
- CVs 1-256 (inclusive) and 512-1024 (inclusive) are to be treated as normal CVs.
- CVs 257-512 (inclusive) are to be treated as paged index CVs, with the page number being stored in CVs 31 and 32 (the index registers).
What this means is that there are a total of 65,536 possible pages of CVs 257-512, so you need to set the correct values in the index registers before accessing any CV in this range.
In JMRI we chose the convention "CV a.b.ccc" for these NMRA-compliant indexed CVs, where "a" is the value to load in CV31, "b" is the value to load in CV32 and "ccc" is the desired CV number (in the range 257-512) on the page specified by "a" and "b" combined.
QSI indexed CVs predate the S9.2.2 indexing specification and use CV49 alone or (CV49 & CV50) as subindexes to ?<257 CVs.
ESU implemented indexed CVs as per NMRA S9.2.2, so you will see CVs like 16.2.384 in these decoder definitions.
ZIMO also followed the NMRA speciation.
SoundTraxx has now implemented S9.2.2 style indexed CVs in its Econami and Tsunami 2 ranges. But they use a fixed value of 16 in CV31 so only quote the value in CV32. So you will see CVs like 1.257 in these decoder definitions.
TCS adopted an even more complex system using CVs 201, 202, 203 & 204.
It is important to realise that indexed CVs are still just CVs as far as your DCC system is concerned. It knows nothing about indexed CVs.
But several issues have arisen:
1) Some DCC systems have problems with CVs>256. For example, I discovered an issue in the NCE Power Pro firmware that causes the wrong CV to be written in Program Track mode for any CV>256.
2) It appears that some decoder brands may have problems processing indexed CV calculations inside the decoder within the timing specifications of the NMRA standards. This can potentially cause issues with some brands/models of DCC system.
3) ESU and ZIMO both provide in-decoder workaround solutions for problem (1) and we have been able use the ESU algorithm successfully in DecoderPro. (But ZIMO provided different solutions with different firmware and as yet no volunteer has found time to resolve this). Unfortunately SoundTraxx has not provided a similar workaround for its decoders.

Re: Having issues connecting on closed Wifi

Sorry you're asking questions above my pay grade.
I have turned off "auto connect" on my phone to the house wifi. So once I'm on the layout wifi it stays there.
