I am new to JMRI (using latest production version), and after much trial and error, was able to get my layout built and signals setup. I used the "NS-2008" signal mast types with "SEC8 4-aspect" signal heads, with SEC8 boards within my digitrax system. And a PR3 interface with Windows XP on an old PC laptop dedicated to the layout.


I was able to build all the signal mast logics for all the signals on the layout, and for the most part all works beautifully. On the double head 3-3 masts, I did "disable" 3 different aspects including "approach medium", "approach limit" and "approach slow". While running and switching an engine around to test out the signals and all the logics I built, I discovered a "bug".


On the two double masts protecting turnouts leading into each end of the train yard, if I align the switches to create a continuous run through the entire yard, both entry signals turn to "STOP". But when I look in the signal mast logic window, the logic line says it should be "clear". Is there a way to fix this "bug"?


Also, on a side note: The JMRI program is trying to show the "flashing yellow" aspect by turning one of the digitrax "turnout commands on and off", when the SEC8 is setup to automatically do it. I have to set the SEC8 4th aspect to "Dark" for the yellow to flash correctly, as well as the flashing green". However, it is sending so many commands simultaneously, the entire signal system is noticeably blinking. Is there a way to change JMRI so it only send the command once for "flashing yellow", and disable the "flashing green"? My layout is so small, I don't have enough track and blocks to run the entire systems as a prototypical system. So I need to simplify the aspects, otherwise I would rarely see a solid green while running a train.



Any advice or support would be great!


Thanks! - Dave

Dave:
If tou up load you panel file to the ProblemsBeingWorkedOn folder in the files area of the group maybe somebody can look at it and figure out what went wrong.

Make sure you crate a folder with your name and let us know when its posted.

Generally speaking disabling aspects has a bad effect on the signal logic, for example disabling 'Approach Limited' will leave the logic with nothing to display when the next signal is showing 'Limited Clear' (red over flashing green), leaving the signal at danger as the only available alternative. The only time you should consider disabling aspects is when the list of available aspects in the signal mast table gets too long (CROR for example) when you manually control the aspects or only use LOGIXs to contol the signals, otherwise leave the logic to worry about what needs to be displayed.


The slow and limited indications should only show if there are track speed restrictions on the selected route, and this will typically happen by default when the selected route is going via the diverging route of a turnout. If you have a continuous run that makes for less than four signals in the circuit consider adding some intermediate virtual signals (with real detection blocks) so that the logic is able to work through more of the aspects.


I suspect that there is no simple answer to the SE8C flashing yellow conundrum. Setting the SE8C to do its own flashing yellow further restricts which aspects JMRI can display on the signal (no flashing red, flashing green or dark as well as no lunar) which would prevent many of the aspects from being displayed correctly.


Letting JMRI do the flashing should not be a huge problem on a small layout where in a worse case scenario only a quarter of the signal masts will display a flashing aspect, but if you have a lot of signals it would be better to use more modern signal mast decoders like the Signalist SC1 instead of the SE8C which support decoder controlled flashing on all of the aspects and just needs a single packet to set the whole mast when the aspect changes rather than the string of packets that the SE8C requires to set each head and further packets every time a lamp flashes.

In , or the files area>ProblemsBeingWorkedOm>WaltsStuff>SE8C is a panel file that shows how to do this.
