Faster baud rate makes for a faster loop, but it’s not entirely proportional. There are also (small) processing delays in various places.

Too fast can result in lost messages. Occasionally, rarely, it can result in corrupt data because C/MRI doesn’t have very much error checking (it usually doesn’t need it)

You could start out at something intermediate and watch the lights. If they’re consistent, no big gaps due to missing messages (which cause a big-fraction-of-a-second timeout), you’re good.

Can we step back for a second?

If you’re expecting to have a Lenz system eventually, why not create a JMRI profile with a Lenz system simulator now? You’ll be able to create layout objects like Turnouts and Sensors, fill in panels, etc as if the hardware was there.

When the hardware comes, most things will just work once you change to a real-hardware Lenz profile. You might discover that the switch motor you thought would have address 14 is easier to connect to 25, and you’ll have to change that in JMRI. But it takes less time to change it in JMRI than it does to wire it in reality, so that’s not a big deal. You just connect each one up, configure it, test it, and move to the next one.

If you decide to buy Digitrax or NCE hardware (i.e. a command station based on DCC communications), all you have to do is configure their system connections with the X letter, and off you go. JMRI is quite happy to have that XT14 that you earlier thought meant “via Lenz” mean “via LocoNet”. Again, you might have to change a few (NCE addressing isn’t exactly like Lenz, in that there’s no sensor 15) but that’s one-by-one thing.

And if you decide to do something completely different, like C/MRI or OpenLCB, you’re going to have to rethink your numbering in any case, likely in small chunks.

You might be setting out on creating bigger tools than you’ll really need when it’s time to work with the real layout.

I have been working away at the Table Records using a Non-Specific System and INTERNAL Blocks/Turnouts but with correct User Names using LE as part of getting ready to create a new configuration when my new Lenz system eventually rolls up and it occurred to me that since we can now pull out the records from every Table and store them away safely in a useful format for another use.

I investigated the problem of Moving/Importing/Exporting Data between different Configurations and landed on Nigel Cliffe's message from February last year.
Nigel's suggestion involved having to Move/edit the records, one by one, into the new configuration Tables where he had already created Blank Table Records in the new configuration. As he pointed out, that would be fine for smaller layouts but what about much larger layouts with well over 100 Turnouts and perhaps over 200 Blocks, etc?

This gave me the idea that perhaps we might be able to combine the "MOVE" function with a modified "Table Move" Script somehow? If we follow Nigel's suggestion and create, say, a Lenz Configuration and fill it with the count of actual records number as Blank Records in every Table. Can the "Table Print List" Script be modified to make it fill/Import into the Blank Records in the Tables using the data stored away, rather than dump them to the printer in .csv format. I am thinking of a more automated version of the "Move" idea suitable for any size of layout.

The fly in the ointment, as I see it, is the inability to create the correct System Name during the creation process. The Turnouts are going to be the major problem. This implies that the correct System Name is going to have to be edited in after import/Move.

Has anyone already solved the problem of moving the Table Data from one configuration to a new one?

Dave R,

So what you are after is a bulk move operation. Typical case is replacing
one system connection with another. I doubt a perfect match between tables
for many systems. Instead I'd say something like a bulk move that sets a few
existing conditions:
1. Both views of the individual connection filtered table must be displayed
in the order that matches the entries. I mean if you start with the origin
as CT1001, and the destination as DT205, the next entry below CT1001 (that
is a CT*) will be moved to the next entry below DT205 (that is a DT*).
2. You have to supply a range number, similar to the way you can create a
number of entries with a starting entry and a range.

I'm thinking beyond the simple sequence systems, or where due to the
hardware, there are gaps in the number range. I'm trying to think of tools
that use some sort of matching or cut/paste of ranges etc... to help this
but right now, I'm not thinking of any good examples.

What I think happens today is people like myself who can attack the file
using text editing tools to do find and replace method, use those tools
(anyone keep up on sed, M4, and awk?) to resort to the changes. Others
either find somebody who can do that trick or use lots of single moves.

That's not true Roger. The PR4 replaces the PR3 and can be used as an interface or as a standalone programmer using JMRI.

James,

I teach Computer Science ( well, mostly software Engineering these days ) at a university and occasionally bring JMRI or JMRI related topics up in classes.

I can certainly provide a few resources that might be useful.

Send me a note off list, and I can forward a few things to you.

Paul

The two sensor triggered occupancy is not a reliable system. Power on's and reversings will give false outputs.

That should be enough for some interesting examples!

It would help to make sure that the NCE USB has a 7.something version of the firmware so you can connect your AIU to get information back from the DB20s.

There’s a lot you can do with that hardware to (likely) raise student interest. From just simple sequences of operations to more complicated things that interact with the train(s) and surroundings.

The extra AIU contacts could also let you can some manual input to the scripts, which can allow a bit more creativity in what they do.

Speed,

The generic NodeMcu is very impressive, and I will definitely be trying some out. Thanks for the tip. However, the typical Ebay price I saw was in the high $3+.? Plus of course the cost of the other end adds up to a $4 -$8 additional overhead for a dedicated per turnout connection. That's not particularly? competitive to a twisted pair carrying +/- 12V.

Unless I've missed something, a wireless TCP/IP net is not IP address selective. So the adjacent layouts could be connected by default at the packet level. Given that the larger? train shows in Europe can have 40 or so layouts, and that many small local shows happening most weekends have half a dozen from a selection of possibly thousands nationally. That implies to me that somewhere, there is going to have to be some kind of authoritative "national registry" of unique "Layout XXXXXX" names. Much like Enet Mac addresses are issued to manufacturers.

I'm still not convinced that a 2-way only turnout is the "fundamental particle" That all other track route changing configurations are made of. ;)?? I have to think some more about traversers and the additional time and length limitations they impose. Gantletts and Multi-track grade crossings are also somewhat challenging in that they are affected by another block's occupancy.

Andy,

There are no dumb questions!

When you look at the 3-way turnout's hardware itself, there are 2 sets of switch points and they need to move, Thrown or Closed. 2 Tortoises, 2 servos, 2 manual gadgets or 2 something elses. So, yes, in JMRI it is currently done with 2 turnouts. Fairly easy to use Routes in JMRI to control the thrown and close of the needed turnouts to get you to the 1st, 2nd or 3rd path by activating a sensor. So, if we put Routes in MQTT, then the relevant subscribers could be told to do something when topic DFW/clublayout/module001/yardladder/route gets a message like "3".

MQTT is not a wireless protocol, TCP/IP is all you need. It became very popular with IOT devices, and that gave it the wireless flavor. The fear about the adjacent layouts being controlled by the same MQTT subscription will need to be just as you would if they were DCC controlled accessories on the same command station. If two modules both use the same DCC address (example #145) for a turnout, both will move. For an MQTT implementation, DFW/clublayout/module001/turnout002 would not interfere with DFW/clublayout/module006/turnout002 or myownlayout/module001/turnout002, if they where to connect to the same MQTT broker. And then of course, JMRI would also need to have all the turnouts in the same table, and thus unique as well. (One of the smart things in LCC/OpenLCB is the 64-bit addressing that would help keep all LCC devices on the planet unique.)

Back to the wired versus wireless question, with a NodeMcu now costing $1.25 <>, I do not know how a "wired" Ethernet implementation would beat that! Noise is a good topic, but not for this thread, this is MQTT in JMRI, and not a "wireless" thread.

From what I have gathered this driver is for a CANUSB and CANUSB2 ( NOT CANUSB4 ).

Ken, Dave,

I never thought about it that way, the Power Cab has no track power switch so it cannot work.

Thanks for the help, I will put this one down to a senior moment.

I relooked at the FTDI drivers. I downloaded the VCP versions, reinstalled and tested. ? Victory !

Thanks,

Sven,

Check Options >> Use Direct Turnout Control in the Layout Editor menu.

If it is checked, then the right mouse button will throw the turnout. If it is not checked, then the left mouse button toggles the turnout between closed and thrown.

Dave Sand

Hi all,

Getting started with Layout Editor to control turnouts on my layout. The turnouts are controlled by MERG CBUS modules. I have defined them in the turnout table and can change them between "thrown" and "closed" without any problems. Good start so far. Then I drew a few of these points in the LayoutEditor and used the entries in the Turnout table. This worked fine and I could throw and close the points by clicking on the turnout icons.

But then I turned off Edit Mode (in Options menu). Now clicking on the turnouts would only close the turnouts. Clicking again would make a noise in the turnout solenoid but the turnout would not change, so something is happening.

Anyone seen this or have any hints on how to trouble shoot this?

Thanks / Sven Rosvall
