Re: Detecting DC vs DCC track power
I understand that but what Im saying is that since you can run DC locomotives on a DCC system you would no longer need to have your layout in DC mode anymore so you wouldnt have to worry about crossing points from DC to DCC because you would always only be using DCC.? If it works for everyone you then disable the DC to DCC switches with no additional hardware or complexity to deal with.
Mike Piazza
Mike, I appreciate the feedback.? I don't _think_ I'm overthinking this idea.? My goal is to prevent a DCC locomotive from going through a cross-over onto a track that is powered by DC.? Also the inverse, where a DC locomotive crosses onto a DCC powered track.

Just some food for thought.

Hi everyone, I've tried countless Google searches, and I can't find an answer to this question so I'm hoping someone here can point me in the right direction.
I am a member of an NTrak group and we support DC and DCC via a toggle switch on each of the three lines. ?
I am planning on building a module that will allow us to cross over from any line to either of the other lines.? I am hoping to create a panel in PanelPro to control the switches, but I don't want the panel to allow the switches to be thrown if the two lines are not running the same power (DC or DCC).
Is there a way to build a circuit (Arduino, RPi, etc) that can tell JMRI if the the line is powered by DC or DCC?? By the way, my electronics knowledge is limited so any and all details are welcome (and probably needed).
Thanks, Doug Mertens

Re: Detecting DC vs DCC track power
Hi,
In theory this should work. The devil is in the details. Many DC power supplies actually put out a pulsed or even PWM waveform that is sufficient to trigger a transformer coupled detector. I know this because we have customers for our CT coil based detectors that use them for both DC and DCC detection. One example is a museum layout that operates with DCC when the club is present and DC when only a docent is present.
Probably the simplest solution is to detect the DC power output and not allow the crossovers to operate when present. A bit more 'exotic' would be to detect both DC and DCC outputs with relays and if both relays are activated remove power from the crossovers. It is not fool proof because it is not fail safe, but probably DC operation has its days numbered. (based on the experience of many clubs that once had dual operation)

Test version 4.13.1 of JMRI/DecoderPro is available for download.
This is the next in a series of test releases that will culminate in a production release, hopefully in Summer 2018.
If you are currently using JMRI 4.9.6 or earlier, we strongly recommend that you first update to JMRI 4.12 and make sure that's running OK before updating to this test release. There have been a number of changes in serial port support, panel file format and configuration options since those earlier releases, and moving to the stable JMRI 4.12 release is a good way to work through any possible problems.
<>
If you use JMRI on Linux or Mac and are updating from JMRI 4.7.3 or earlier, there¡¯s a necessary migration step. (Not needed on Windows) Please see the JMRI 4.12 release note for details: <>
For more information on the issues, new features and bug fixes in 4.13.1 please see the release note:
<>
Note that JMRI is made available under the GNU General Public License. For more information, please see our copyright and licensing page.

The download links, along with lots of other information which we hope you'll read, can be found on the release note page:

Re: Detecting DC vs DCC track power
What you want is there to be no voltage across the gaps when you get there. Bad cases include: *) Both sides DC, but set to opposite polarity *) Both sides DCC, but wired opposite or running off different command stations *) One side DC and one side DCC I suggest you put a pair of oppositely-wired opto-isolators on each gap, a pair on each side. Pick limit resistors that¡¯ll let them survive 30V, and still work down to about 3V. Have those feed whatever indicator you want. If any of the four are conducting, there¡¯s voltage across the gap: don¡¯t go there. Which ones are conducting, and whether they¡¯re on all the time or rapidly going on and off, will tell you which problem you have.

Without any DCC++ hands-on experience, and very limited DCC Turntable experience, not all of what you wrote makes it through to me.
Can you watch the JMRI System console and the DCC++ Traffic Monitor with both the "Show raw data" and the "Show timestamps" turned on? Even better, use the "Choose log file ..." and "Start logging ..." features.
Together, these should give you a better idea as to what the DCC++ is trying to do or not do with each of the actions you describe. With that kind of information, you should be able to narrow the investigation focus.
There are ways to turn on more Debug logging messages to the JMRI System console window, but someone with more DCC++ experience will need to help out. My experiences with verbose LocoNet chatter will not help you in the slightest.
By the way, you can also upload images and files to this groups.io account and avoid sharing the strange adds, .
It may be necessary for you to upload your panel .xml file for someone to dig into what you have done, but hold that thought until you get someone else to help here.

Re: Inconsistent behaviour with the dispatcher
The previous posting relates to the block warnings. I don¡¯t know if they impact Dispatcher actions. A Dispatcher expert may know.
For you questions, setting up a test scenario would be required. I might play with that tomorrow.
Personally, I eliminate all errors and warnings before moving to the next level. For me, the levels are: track > blocks > signal masts > signal mast logic > sections > transits.
Since I don¡¯t have a layout, I include the occupancy sensors on the panel to simulate train movement.
