Mick,
I haven't.? It was JMRI saying it could not contact Command

Thanks for the reminder.? Yes I know they're relevant (CV837 and CV843? not 841! ),? and they need to be part of the same "pane" in the JMRI programmer interface.? ?
I'll update those in the file for CV700-899 when submitting the change request.??
For now my first files covering the script variables only are out with David who posted the question.? I'm confident they'll work because its just access to a decimal CV.? But I prefer testing a feature with an actual decoder.? ??

Just a little tip (but you probably already know that): The two CVs 837 and 841 for deactivating scripts are also part of this CV overview.

Re: Java exception when starting JMRI 4.20 with Java 17
Adding to Wouter, the further “behind” you get from current, the bigger the task (and risks) there will be if/when you DO need to upgrade?
My oldest environment is running Windows 8 (still) and I really can’t remember the last time I hit a problem when upgrading. All my JMRIs are current

Don,
For new and improved features, the releasenotes are the place to look. Also, there is no shame in being happy with an older release. Having said that, it's nobody's task to convince people one way or the other. It's everyone's own choice to update, not
to update, when to update, which version(s) to update to. One thing that will become increasingly important, is that if support is necessary, the older the version, the less likely people iving support are going to be willing to invest their precious time

Uninstalling and upgrading your JAVA is just the beginning of PITAs involved (not to even mention Windows versions needed and its hardware requirements), and no one has ever given a single, solitary example of some extra, additional, or improved feature
that a later JAVA version has. I've asked before. Of course, if anyone can offer anything like that now, then knock yourself out. That would contribute to the discussion.

Re: Problem getting started.

The SPROG only turns on the Track Power momentarily during? all the programming activities. This is designed? to ensure that a Programming action on a newly installed or connected decoder will not destroy a wrongly connected decoder.
To really see any voltage on the Trk connections, use the Power button on the top of the Roster screen (probably Red right now) to switch it to Green. The SPROG Power light should now flash slowly, and you can see AC voltage on the track connections. Note: most cheap multimeters are not good at showing the actual voltage, but should show something on an AC range. DCC is a square wave AC waveform at higher frequency than AC power from the wall at 50 or 60 Hz, and so is not typically read correctly by normal multimeters.
?
But,
back up!
?
Do you know that the SPROG is correctly connected to your computer?
Open the SPROG Console from the SPROG (or similar) menu. You should see several lines of commands, one of which will show the SPROG version. Your computer/JMRI does not know that version, and so has asked the SPROG for it. If you see a version there, your SPROG is in touch, and you can move on to trying to find power!

Thankfully I can now connect to my EasyDCC command station via my Windows 11 laptop.
When opening the DecoderPro app I'd always clicked on 'My JMRI Railroad'. However, when I now do this my roster page comes up with all locos listed but no ability to program via the main or program track.
However, when fiddling around I decided to click on PanelPro instead and the connection to my command station worked, but there were no locos listed. I had to re-create the roster in PanelPro and, bingo, all came good.
So, now have all working and can program on the main and program track via the PanelPro item instead of usine the 'My JMRI Railroad' profile.
Happy that things are working but the question remains as to why?

Adding Signal Heads @ Dbl Slip using "Set Signal Heads at a Slip" Tool
#ssl
#layouteditor
Good evening Moderators and group:
?
My setup:
Win10, Digitrax PR3
Digitrax DCS210, DCS50 (throttle/ booster only), DT400, DT500
SE8C x2, BDL16 x2, SE74 x2, DS64 x4, UR90 x2, UP5
Signals are Digitrax SHABC and SH2AB
Panel Pro 5.2+R760b98537f, java 11.0.19
?
The layout is essentially a reversing loop to reversing loop arrangement, with SSL installed over most of the layout and working correctly.
I have a Layout Editor panel which correctly displays occupancy, powered turnout positions and signal aspects and correctly match what is displayed on the physical layout.
?
There is 1 powered double slip that I am now trying to add SSL to using the "Set Signal Heads at a Slip" Tool.
I used an earlier post by Dave Sand as a guide ... #233359.
However, I get the following error:
"Cannot set up logic because next signal (in or at the end of block "Block_1" is apparently not yet defined"
There are 4 block boundaries defined (the slip is part of Block_1 as well), and signal heads at all of these boundaries.
If I try to "Set Signal Heads at a Block Boundary", I get an error message that the signal heads in question are already in use on the layout diagram.
?
I placed most of the signal heads on the layout diagram and created the SSL without using the "Set Signal Heads at a Block Boundary" or other tools ... could this be part of my difficulty? Perhaps it's time to move to SML?
I would be grateful for any suggestions as to how to proceed from here.
Thank you all,
Paul Young

Is there a reason you have not updated to at least the latest production version of JMRI? 4.20 was almost 5 years old, 4.26 is over 3 years old.
I wouldn't expect support for such outdated versions.
