Dave in Trempealeau this question is for you.? I searched but only found thousands of sites related to 4 legged cats.

Dave...in Colorado

Solved.? Problem was with how the RPi assigns ports.? When only the DCC++ was connected it was assigned ttyACM0.? When two devices are connected the first one RPi recognizes is given port ttyACM0 and the second is ttyACM1.? When you plug in a 3rd device OR unplug a device and re-plug it that device will be given port ttyACM2, and so on.

So the RPi saw the port with the LocoNet first and assigned it port number ttyACM0.? I switched the ports in Preferences and the problem was solved.? This would make a great comment to add to JMRI help.

Ken, thanks for suggesting the ports issue.? BTW the defaults were correctly assigned to DCC++.

Thanks everyone - I created a class called runTask? and called it with the standard invocation? runTask.start() as Bob suggested and it worked for me.

Billybob - sorry did not know about the developers group so will go take a look at that for future reference.?

James,

Your issue contains some deep programming issues and may not be of interest to the average jmriusers list member.

The jmri-developers.groups.io list is more programming-oriented, and is a better fit for your issue.

Regards,
Billybob

Take a look at the jython/BackAndForth.py sample script. (In the JMRI distribution or here: )

It creates an indepedent thread via the AbstractAutomaton class, which handles those details. That then waits for sensors and commands a throttle.

Hi, I have included a small cut down version of something I am trying to do.

I set up a propertyChangeLlistener for a sensor. When the sensor is activated it runs. I have simulated it running a long time just by putting a time.sleep in.
My problem is that when the se.setSate(ACTIVE) in the main function runs. It does not complete until the propertChangeListener completes.

Is there a way to have the propertyChageListener run without the main function waiting for it to complete.

I have looked at some of the documentation on threads but do not understand how to get this to work with jython.
I have used threading.Thread from the standard library start a thread running to do the long running task but this has some really strange behaviour and does not appear to run as thread but runs sequentially.

Some examples of why I want to do this is that when a sensor is activated I want to set a function key on the throttle a number of seconds later and not at the time the senor is activated or to start running some animation program on the layout that
could take some time.

Thanks jim.

Thanks Steve, the main problem has been resolved, actually quite simple, I had a turnout MT+N0E9 as well as MT+N0E09, same for E6 and E7.
Checking the turnout table in 4.14 only showed N0E9 and not N0E09 and I guess the new address validation in 4.18 quite correctly picked up on this.
No idea why but could not delete the turnouts using the button in the table, clicking delete had no effect even though I had removed the signal heads associated with them, no error message, edited the XML and the panel now works with 4.18.

PT5/6T-11T-PT7C-PT8T-PT9T etc. are just user names, the system name follows the standard JMRI / MERG naming convention.
I use Logix to determine the state of the five turnouts, "PT5/6T-11T-PT7C-PT8T-PT9T"?will be Thrown if any of the turnouts are not set as required, setting PT5/6T-11T-PT7C-PT8T-PT9T to Closed changes the turnouts to the required position by sending a specific event e.g.+N0E103 which has been taught to each of the turnouts. Makes the Jython script a lot simpler, just one route to check and set.
I used Node 0 as I thought this was necessary as the event is produced by the PC / JMRI but since learnt that I could used any node number providing it was not a duplicate.

Thanks
Pete

The release notes already cover how to use the old CSV API by linking into the documentation for setting JMRI parameters.

The draft release notes for 4.19.3 are at

Dave,

You should do the test of watching /dev while plugging and unplugging the
devices. From the confused traffic, I would suspect that the picks might be
reversed for the ports. ttyACM1 and ttyACM0 may not be the device you think
it may be.

Make sure of which name shows up when you plug in the device.

Dave,

You might want to check the Edit->Preferences->Defaults, it may not have the
selections you think it should. It may have some things defaulting to the
LocoNet that should be on the DCC++.

One more thing, on the PR3 the green LED is mostly on and winks off and the red LED is on solid indicating no LocoNet signal.? So yesterday I unplugged the BDL and plugged a LocoNet cable from a DCS50 Zephyr into the PR3.? The red LED went out, but the problem in JMRI with Unknown throttle was still there.

Below is the info from the System Console:

Thanks for the help!

I created the Decoder File for the Digital Bahn WaLD Decoder and it works. So from now on, i can set up the interior lightning stripe with decoder right aut of jmri.
I think, i will upload the files to the projekt, so everyone can use them in future.

I have a small track that has been successfully running DCC++ connected to a Raspberry Pi currently running PanelPro 4.6.? I am attempting to add block detection using a BDL168 and PR3.? I use TightVNC on a laptop for programming the RPi.

First, the track was cut into 16 blocks with feeders thru the BDL and the train ran normally.? Next, BDL OpSw 12 was set to "t" to terminate the LocoNet, and track power from Rail A was connected to pin 6 on the LocoNet to provide a RailSync signal per the BDL manual.

Opened Preferences to add a second connection: Mfr - Digitrax; Connection - LocoNetPR3; Serial port - /dev/ttyACM1; Cmd station - Stand-alone LocoNet.? Saved and restarted.

The console window shows -?
Active profile: DCC++
DCC++: using DCC++ Serial port on /dev/ttyACM0
LocoNet: using LocoNet PR3 on /dev/ACM1

The track power button is stuck on "Unknown".? Removed and added the PR3 to Preferences a couple of times with the same results.? Tried Steve Todd's latest image v4.18 with the same results.

What am I missing?? Where do I look next.? It's probably something simple that I have overlooked.

Thanks for any help or suggestion you may be able to offer.

Dave

Dave,
Where is the new CATS group?
Thanks,
Ray Eiser

Rodney,
Thanks.? We read about CLEAR is section 6.2 but it didn't sound like what we wanted to do yet it is exactly what we were looking for.? CATS is working well so far.
Dave...

Are drivers installed for the LocoBuffer?
