Re: 4.12 JMRI Web Server Crash on Startup
Wouter,
The reason for the reference to Eclipse in the error log is due to the fact that we use Jetty as one of the web server components, which happens to be an Eclipse foundation project (hence the use of their namespace).
Pierre,
The error you're seeing is indicative of old versions of the jetty files still being accessible in your JMRI installation, in the 'lib' folder.
Jetty .jar files contain the version details in their filename meaning that on Linux installations, just copying directly over a pre-existing JMRI installation runs the risk of older versions of these files still being accessible.
As Steve mentioned earlier, the easiest fix for this is to re-extract the new JMRI installation into a completely fresh folder, either by deleting or renaming the existing one.
Best regards,
Matt H

Re: Exception while setting Signal Logic attempting to set invalid aspect
Greg,
Based on my experience, double cross-overs are most likely to suffer from the backward looking logic. This can also occur when there are two cross-overs using the same blocks. This is effectively a double cross-over.
When I run into one of these, I delete the bad entries and manually create the missing entries. To do this, turn off the Use Layout Editor options and enter the blocks and turnouts in the manual section.

I had neglected to remove those mappings from that signal set so JMRI was looking for Diverging Approach and causing him to have an error. The second issue he has with the panel is the crossovers are not allowing signal mast logic discovery to function correctly. Sometimes the mast logic chooses a signal that is behind the source or facing in the opposite direction.

In this photo the signal that is circled is mapping to a signal in the opposite direction. Discovery ignores the two signals on the right end of the diagram which should be the destination signals.
/g/jmriusers/photo/79332/1?p=Name,,,20,1,0,0
In this shot, discovery finds three destination signals one of which is facing the opposite direction.
I'm not certain how to fix the discovery issue other than delete them. Perhaps Dave Sands or one of the others can help with that.

Re: Entering New Loco's in DEcoder Pro
Peter and Mike:
I am having exactly the same problem with reading and programming the BLI F3/F7 units with Paragon3 "Rolling Thunder" sound decoders in them.? I am using a standalone PR3 with a programming track, and an 18 V power supply.? I get exactly the same behavior as Mike described above, in all aspects.? I eventually used NMRA Standard Definition for these locos in order to be able to change their addresses.? Not a satisfactory solution, but at least I can program the address.? Other BLI locos with the Paragon3 "Rolling Thunder" decoder read and program just fine.? What gives???? Anyone have any suggestions??
Thanks!

P.S.? The new BLI T1 steamer behaves exactly the same way!!

I've had both of my PA's quit reading ControlBus that's the smaller RJ with two wires to ControlBus and switch 1 change. I power the PA from and external power supply.
According to the PA manual, DIP Switch 4 is the only one that does anything.Don't even think of closing JP1 and JP2. That will break the optoisolation as it tries to power the PA from the Track DCC power at pins 3 & 4 of the 4 way socket. This will likely create havoc (magic smoke escaping) unless your computer is a fully floating laptop with no mains or other connection (e.g. to Power Pro serial port) and you have nothing connected to the 6 way socket. These old devices are too precious to risk destroying.Powering the PA via pins 2 & 5 of the 6 way socket by plugging it into the NCE cab bus is safe and reliable.
Before they quit I did use JMRI to read the data... and on both the CabBus and ControlBus with no crash on either a JMRI Raspberry Pi or Mac... Use to with old PC years ago...
If you have a terminal program on your PC you can try that to see if JMRI/Java is the culprit rather than just pumping the data into the PC..?
Mine is working fine, been dumping data flat out for an hour or more with no crash. I've even done multiple "Freeze Screen" and "Info/Resume" to try to trip a buffer overflow, but not fazed.BSODs are very unlikely to be caused by JMRI/Java. Very likely to be caused by USB-Serial driver.For a non-JMRI option, I frequently use CoolTerm on Mac and there is a Windows version:
If using the non-JMRI option, call up the help screen by pressing "?"
From the PA Manual:? Data Communications We¡¯ve had good luck using Hyperterminal supplied with Win98 and Win XP. The communications settings are 38.4kbps, 7 data bits, 1 stop bit. Use the ¡®No Flow Control¡¯ option. The analyzer does not echo characters so you may also want to turn echo on. Also turn on ¡®Append line feeds to incoming line ends¡¯ under the Properties->Settings->ASCII Setup menu. Before connecting the analyzer to the track or command station verify communications by pressing ¡®?¡± to get a menu of commands and the analyzer software version.
Is the port on the PC a "classic" RS232 or are you using a USB dongle?
If a dongle, what make and model. Dave in Australia

Assuming you have the right hardware (MXULF), you would then startup JMRI "WiThrottle"i throttle server.?
An App on Andriod or Apple phones can then connect as throttles.

Re: NCE Packet Analyzer Crashes
The NCE Cab bus is monitored by setting DIP Switch 4 on before power up. The output isn't terribly informative as it consists mainly of cab pings from the command station, LCD display quadrant updates and the occasional key press. I just tried with JMRI V4.13.5 and it's been spewing out data like "80 81 82 95 96 AA" for many minutes now with no signs of a crash.
The NCE Control bus (a low current version of the DCC track bus - the booster input signal) or even jumpers to the track via pins 2 & 3 of the small 4-way Jack is monitored by setting DIP Switch 4 off before power up. You can then use the radio buttons to change the display format between decoded user-friendly output (Verbose) to various hex formats of the actual DCC packets. You need to use the "Show xx" radio buttons to show various packet types otherwise display will be blank. The "+ on" checkbox suppresses repeated packets, replacing them with "+" symbols. The "Info" button interrupts normal communication to ask the analyser for a comfort command help screen (JMRI is using those commands when you click on radio buttons).
Your BSOD has to be a USB-Serial cable/driver issue. What brand are you using?
Make sure you try JMRI 4.13.5 - just in case... I avoid V4.12 as it has many issues.

Decoders on the railroad can be read as on a programming track... However...
This isn't easy without some other tech... Digitrax has it's transponding and in Europe there is RailComm where decoders can transmit data. Neither supported by NCE.
An alternative is an RFID tag and reader to identify a locomotive. One source is...
This is a Raspberry Pi and Arduino system.
MRH ezine with their NMRA convention coverage mentioned a company TrainTraxx that has a different system that's cloud based with only a promised connection to JMRI.

NCE layout is up and running.? Using NCE SB5 USB interface v7.3.2. I've written a logix to sense the end of track in a 8 track passenger station.? Once the reed switch is sensed, the logix script rings the engine's stop bell and stops the train just before it reaches the end of the track.? Works great. For testing, the Jython script, executed as part of the logix, has a hard coded short address for one of the test locomotives (stored as LocoID).? I want to now generalize the script and combine it with the block sensing script to do three things: get the address of the loco that has entered the track, send a throttle slow down command to slow own the train to about 15% throttle and pass the engine short address via memory variable to the logix script, so that it will stop whatever engine enters the track. Each of the station tracks is a separate block with a separate NCE BD20 sensor that reports the engine entering the block (track), but I can't determine how get the loco address that entered the block. This should be pretty straight forward, but look through some example scripts for ideas.? Can anyone provide some help?
Thx Norb
