Loco moving only during sensing decoder type | Decoder Pro
Recently bought two locos and whenever I put them on the programming track with JMRI, the trains only move incrementally backwards and selects multiple possible decoders (none of which work). Using throttler on the decoder address it sensed did nothing. Is there a reason for this or a cause for concern? Video below highlights the issue,
I have a Bachman 60804 HO scale Great Northern GP30 Diesel locomotive #3007 and am using a DCCEX command station. Any help/advice is appreciated, Thomas |

Re: I have apparently created a loop or message storm in Loconet - I don't know if it's JMRI or not -- any suggestions on how to diagnose?
Well, I changed all the masts (about 35 of them) to a send count of 1 and the problem went away. That MIGHT have been the answer, or I did something different in the startup sequence, or it was something entirely different. We may never know.? Thanks for the suggestion -- it was probably a good idea to do even if it wasn't the cause of the problem (or maybe it was?).

I have apparently created a loop or message storm in Loconet - I don't know if it's JMRI or not -- any suggestions on how to diagnose?
I have been working with my panels (current version at /g/jmriusers/files/ProblemsBeingWorkedOn/Scott_Waltons_problem/PRR_West_CTC_cleaned_fourth_reset.xml)?getting the Signals correct (especially around the double crossovers). I got those apparently correctly and managed to get several Transits to correctly circle the railroad (mostly - a couple of pauses here and there). I went to work on it again and when I turned on power to the railroad, I noticed that the Loconet became VERY busy and never went idle. When I looked at the Loconet monitor, there were many "Send IMM Packet command" messages and most were rejected as the buffer was full. I turned off power to the railroad and then restarted JMRI -- the same situation recurred. I again turned off the railroad and this time started JMRI on a different computer, connected to the same railroad. I started a monitor capturing the Loconet data. The messages didn't start again I restarted the PanelPro with the panels in the files section. Then the messages started again, but the curious thing is that they didn't stop when I exited PanelPro, so there must be something in the LocoNet devices that is either sending or resending these messages. The Monitor log has been upload to the same file area (/g/jmriusers/files/ProblemsBeingWorkedOn/Scott_Waltons_problem/monitorLog-alpha-full3.txt). No errors are showing in the System Console window.
The environment is: Windows 11, Java 11, command station is Digikeijs DR5000 with DR5088RC Railcom readers, and RR-CirKits devies (SignalMan, TowerMan, MotorMan, TC-64, TC-64 MKII). Any suggestions on how to narrow down this problem. I think it would help if I was able to decipher where the Send IMM packets were addressed. Scott Walton |

Re: Question about JMRI operations
#operationspro
And I should apologize, as I may have miscommunicated in an earlier post when I said..
...you can dial down the number of pages if you lower the route detail to the middle detail (check the middle of the three choices).? Also reset the font size to minimum of 7 for the report.I should have pointed out that there are 2 detail Levels you can adjust.? Both are found in the?Trains Window--->Tools--->Build Report Options. The first is the "Detail Level" and this is what I think you may have changed based on the build report you posted.? However, this level should be left on "Very Detailed", which, on the version of JMRI?(v. 4.22)?you are using, should be the 3rd button. The second detail level is called "Router Detail Level" and it only becomes active when you select "Very Detailed" from the Detail Level section.? This is the button to which I was referring previously when I mentioned lowering of a detail level... So, to reiterate, in the Build Report Options window, under the section labelled Detail Level, select the button labelled "Very Detailed", and under the section labelled Router Detail Level, select the button labelled "Normal". And while in the?Build Report Options?window, consider lowering the font size to 7, as this makes wrapping-text less of an issue in reading the build reports...? Happy to help, hope it helps,

Blair,
Not pot stirring at all! Lol! All useful comments. Looking at my test rig, it is a rats nest of jumper cables. They are easily disturbed and a bit confusing at times. I can't see anyone wanting to use what we've done if it ends up like that! So basically, I was thinking of trying neaten it all up a bit. I thought that up to eight sockets could be used to plug the readers into. Then the seven wires from each reader can be easily routed to where they need to be. The question is, where do they need to be with three different boards! I felt the easiest thing would be to have an on board Nano socket to directly plug a Nano into. If you want Ethernet, than that could plug in with the Nano. Would you need an Uno as the Nano can do what the Uno can? So that just leaves the Mega. So I thought a row of breakout screw terminals could be present to allow wired connection to a Mega, or indeed an Uno if you realky wanted. Although we haven't sorted this out yet, the pcb might also have to accommodate a 9v jack, 3.3v voltage regulator, level shifters and possibly a multiplexer. I'm not sure how we accommodate the Seeed readers. Who is it aimed at? Anyone who wants a cheap RFID system. After all this, I would certainly have a few! You are right, there might be a bigger audience over on the RFID group, but I think most of them are keeping an eye on this thread too! Keep the thoughts coming. Steve |

Tom, Steve
Here comes that pot-stirrer again.? What/who is the intended target for PCBs?? I agree, a discussion needs to be had about essential/wanted/desired features to put things into perspective. Also, although these boards would feed into JMRI, is this something that should be hived off to the RFID list, instead?? It might get a larger audience that way. I'd like to contribute, but let's figure out the ground rules first. Blair considerations we have tossed around here in terms of the level of versatility we'd LIKE to >>have. I imagine that the PCB could use enable/disable jumpers for a slew of function types, but the electrical components we will need and how they connectThe PCB stuff is a different story entirely since there are a LOT of to work with all 3 board types.correctly may get complicated fast, especially if we want the thing |

I spent a LOT of time ensuring the pin assignments are appropriate for all 3 board types and am pretty confident that the sketch should also work as expected on the Nano and Mega. As far as the MUX, I have a MFRC522 serial sketch for using a MUX. The code for doing that is fairly straight forward if we need it.

Re: Does type of DCC decoder matter for JMRI?
Thank you! So, the board that came with my loco had an internal dcc decoder on the big main board? I didn't even know that was possible haha. I am going to take your advice and just replace the main board with the?NCE board replacement decoder Bach-dsl and hope it gets sensed by JMRI.

Tom,
As you say, we have a number of working sketches now. I think there are still a few tweaks to do though. I like whatt you did with the PN532 sketch where it flashes the led for the number of readers and lists which ones are connected to which pins. That would be quite nice to have on the MFRC sketches too. Currently, the PN532 sketch is Serial only. I think it would be good to have an ethernet version too. So far, I've really only tested one reader with an Uno for these sketches. We need to test them on Nano's and Mega's to be sure. I also need to test multiple readers once the hardware has arrived. Then we can see what issues, if any, we get with 8 readers into a Mega. We might have to use a multiplexer and this would need to be added into some of the sketches.? Once we've done that, I guess it's time to look at an easy pcb board for connections. I quite liked the idea of a Nano plugging into some headers on the pcb. I see you can get an Ethernet Shield for a Nano too? think it would also be useful to make provision for connections to Uno's and Mega's. What are your thoughts? Steve |

Ethernet and WiFi
Tom, I'll post the exact working Ethernet sketch when I get home from work. I also want to see if it will work without the Ethernet Shield attached. If it does, then we don't need an Ethernet and Serial? sketch. I'll have a go at changing pins around on the WeMos and see what happens. Steve |
