I really like Decoder Pro. But, the ESU Programmer is significantly faster at reading/writing ESU decoders. Is there a command station or other computer to DCC interface that I can use with JMRI Decoder Pro that would give me similar read/write as the ESU Programmer? It is my understanding that the weak link of decoder pro is the computer to track interface. -- Heath @ Human[c]ity http://www.humancity.org http://www.riversidetransfer.nyc http://www.manhattanmodelers.com

I created a simple panel using Panel editor and placed PanelPro.gif on it as a 'background' item. Now I can't delete it. What is the trick? George

My staging cassette will accept maybe six 40ft boxcars. I'd like my daily turn to drag more than just six cars to staging. Right now, ops build will only populate a train for that staging "track" capacity. Has someone developed a strategy to select multiple cassettes for destination rather than the default empty one? I tried to figure out using "alternate" track but mind twists in a knot. The cassette is designated "staging". Should it be designated something else to enable a strategy? -- Ken NYNH&H, Old Colony Division, Cape Cod Branch (1949-1959) Loconet * JMRI 5.11.4 * OSX,Win10,Ubuntu Blog: Cape Cod Railroad (HO) – Newbie of an Oldie Youtube: Ken's Channel

Hi, I was programming an ESU Loksound V5 DCC decoder and noticed i could not activate any function above F12 using the JMRI Throttle in Decoder Pro. I had another locomotive with a V5 decoder so i also tested the issue on that with the same results. I'm using the PR4 as a standalone programmer on a dedicated programming track. The PR4 has the latest drivers from the Digitrax website and i also tried flashing the firmware. Is this a limitation of the PR4 in standalone mode? Am i missing a specific setting somewhere in Decoder Pro?

All, I am still quite new to DCC model railroading - working on a trial N scale layout with about 18 blocks, 4 trains etc, controlled with JMRI etc. THe learning curve, and some frustrations with Digitrax, loconet, and JMRI 'steep' learning curve have me wondering what the future (near and longer term) of control may look like (and I am a career chip design engineer currently trying to learn about AI topics for electronics design- so a bit of an electronics nerd). So I am eager to hear from the prognosticators, naysayers, and visionaries on this group. Are there big technology changes coming in the near and mid term? Bluetooth communications to all trains/rolling stock/sensors/lights - is IoT coming to the model trail world? What about other ways to know where your trains are? micro GPS locating? Has anyone done a system where one or more video cameras is used to look at the layout, using vision processing in real time? (sure seems like a task made for AI)? And AI - is anyone using AI to write their JMRI scripts or otherwise control their layout? How about lighting? I foresee doing an entire set up for lighting from a single strand of individually addressable LEDs (controlled by an Arduino perhaps) under my layout and running a fiber optic to each 'lighting point' up through the layout.. Is that done? Perhaps I am being too geeky - I really like the real time operations and control challenges with this so far - and am just starting to think about the aesthetics - of scenery and themes. Thoughts? - or point me to the dark corners where this discussed! -Peter

Hi All, I have added the panel file exhib.xml to the David Smith folder in ProblemsBeingWorked There are some issues with some of the signal masts. Could someone please advise what the problem may be ? Buffer masts Mst_Buff_SdS4, Mst_Buff_SdS5, Mst_Buff_SdS6 are set to Unknown Mst_SE3, Mst_SE2, Mst_SW3e, Mst_SW3f, Mst_W4 signal logic does not see other masts correctly ( I am aware that I could fix the issues by manually editing the signal logic but would prefer not to ) Can I also please ask, if I add a mast that is not visible on the panel, is there a way to see or edit it afterwards ? Also, can I ask why all of the signal heads appear in the Turnouts table ? Thanks Dave

To ensure the whole train is considered when assessing block occupancy by current sensors and not just the current drawing locomotive the standard solution is resistive wheelsets. However JMRI knows (with speed profiling) the speed of a train and can also record its length. Along with block length these values would allow a calculation of the block occupied by the end of the train. Would it therefore not be possible to show a block as occupied until the end of the train had left it? I can't find any information on this functionality within JMRI. Is this something that could be implemented on top of JMRI in (say) python or java? Anyone explored this? Any ideas?

I'm working on a script to facilitate virtual block handling (time before unoccupied, etc) by considering time entered and exited and block length. Since every car being pulled draws power I can estimate how long it will be in a virtual block (assuming same speed). The script is loaded at startup and adds property change listeners. Since I'm learning JMRI I have to make incremental changes and every time I have to restart since the old listener is still active. Maybe I could save my chained listener objects in a memory and check if it's there if I re-execute the script but wanted to check with experts first. Is there any advice for avoiding a restart?

Greetings All, After an extended late-night dive into the group archive, I can't seem to find a final word on whether the JMRI DMX-via-USB support (whether Anyma or Powerline) works when using Java for ARM on Apple Silicon Macs (M1-M4 processors). There are a couple of 2022 threads that mention that it was broken, but the only possible response I found in the code was a commit for release 5.3.3 that appeared to be a minor change for some component of DMX support. It didn't look like a smoking gun, but looks can be deceiving. I'm asking because my 2020 Intel iMac will likely need to get replaced with a M4 (or later) unit sometime between now and when my layout is getting built. I can certainly buy a USB-to-DMX dongle, a decoder, some lights, and play around with it, but that won't be a true acid test since I'm still back in Intel land. The ultimate goal is to have the layout lighting run in two modes: Maintenance mode - All lighting turned on, with RGBWW strips at full WW. Operations mode - All lighting and color reacts to the time of day, based on the fast clock time. My assumption (at the moment) is that this functionality would likely require either a LogixNG or Python/Jython script that listens to the "maintenance mode" memory value and the fast clock value. Thanks in advance. Paul

I have just taken delivery of a loco fitted with the above decoder and carried out a CV “read all sheets” with DecoderPro. It appears to not display CV numbers greater than 841. How do I read/write these? I am familiar with ESU’s Indexing process to access a large number of CVs, but can only find a process called scripted CVs in the Zimo instruction manual. Maybe I am dumb, but definitely need help here. Thanks in advance.

Getting a new MacBook Air next week to replace my 4 year old MacBook Pro that I use DecoderPro on. I'll be trading in the MacBook Pro when I pick up the new Air. What JMRI items should I back up (to iCloud or portable hard drive) before I go to the store? I already save the Roster File and Roster.xml to iCloud whwnever I make changes in DecoderPro. Any special Java installs to be done of the MacBook Air? Thanks. Fran Giacoma

I have a yard setup with 8 C/I tracks for various next destinations so we can sort cars as they come into the yard. I also want some extra storage space available to each C/I track so if a given track has 8 car spots available but 10 cars that should be placed on the C/I track the software has somewhere to put them. To make it more complicated lets assume that the outbound train can only handle eight cars So, ten cars come into the yard for Woodsville. Eight go onto the Woodsville C&I track and the other two go into "general storage" When the time comes for the Woodsville train it grabs the eight from the C/I track, freeing up room for the other two cars to be placed on the C/I track for the next train. A yard job then runs and puts the two from general storage onto the Woodsville C/I track Two questions: What would the real railroad do? Is there a way to accomplish either my idea or the prototype solution in JMRI? Thanks!

Why when adding a BLI locomotive are labels automatically imported, but when adding a locomotive with an ESU decoder there are not any labels. Is this in the decoder default mapping and is this something that can be updated? I really do not want to have to manually enter all the labels on every locomotive with an ESU decoder. Or is this operator error? -- Heath @ Human[c]ity http://www.humancity.org http://www.riversidetransfer.nyc http://www.manhattanmodelers.com

I see some posts about JMRI / CMRI over ethernet. Is this possible? I'm lost and can't figure out how to post to a certain user. Any help appreciated. Jim Loftin

Hi, I am using PanelPro wirh MERG and a SPROG and everything is great, But I want to build the Panel and develop scripts without the MERG hardware and SPROG connected, and PanelPro will not open the panel unless the hardware is present. Is there a way to be able to do that ? Many thanks Dave
