Apparently testing if? s == null is not the way to do it.
Could someone point me in the right direction how this is properly done in a jython/python script?
Thanks for any help!

Re: Decoder Pro returns 123 for all decoder settings
One thing: the upgrade alone is not enough. Whether before or after upgrading, you will still need to go to the preferences and correctly set everything up. After that, 4.12 will leave things be, whereas 4.10 will mess up at every opportunity it sees...

Thank you to everyone that contributed to my problem.? I have at last a train that can go around a loop with Dispatcher and stop in the station and then continue after a time.? I have successfully used physical sensors, internal sensors and logix to accomplish this.? One question remains.? How can I reset each block to inactive in logix, after they go red on layout, so another continuous journey can happen around the loop again?? Thank you all in the User Group.? I couldn't have got this far without you.?
Best Wishes

What would you use to trigger the missing layout sensor(internal) to be active. Could you say when previous block is occupied to turn the internal sensor active after a delay guessing when the engine would hit the block?
What other ways are there that are possible.

The biggest challenge is that you also have to simulate the direction of traffic so that the virtual sensors become active and inactive in the correct sequence. ?Otherwise the block routing breaks down which causes Dispatcher errors.
It is a trade off between cost and dependable operation.

Graham,
The best way to look at Logix is you make groups of Conditionals. Each
Conditional has two parts: conditions and actions. The conditions are things
like sensors and turnouts that you test for some logical state like true or
false. You can use AND and OR or even mixed to build these lines to some
logical conclusion. Then the action lines are doing something, like setting
turnouts or sensors, etc... based on the conditionals coming as true or
false.

Re: Using a Large Number of Connections to JMRI
Large numbers of C/MRI connections via Ethernet should not be a problem. Each one will use less than a MB of additional RAM. The network stacks are pretty efficient of CPU time, and don¡¯t care about numbers of nodes for much larger numbers than anybody will realistically build. Large numbers of USB-connected devices can be problematic unless you have (and your OS supports well) multiple _independent_ USB busses. The USB controller hardware that runs a bus typically has a limited number of slots: RPis seem to have 15, most modern Mac hardware has 30, and PCs vary from 7 to 20 or so. Don¡¯t forget to count built-in devices like the keyboard and mouse if they¡¯re on the same controller. Bob On Jul 19, 2018, at 2:50 PM, jerryk4884@... wrote:

At our club we have a windows 7 32 bit computer loaded with Decoder Pro 4.12 with the latest JAVA for 32 bit. It is connected through USB com port 4 to a Digitrax DCS 240, Decoder Pro set as a PR3 connection. We can read and right to decoders, but the throttle will not control a locomotive. Digitrax throttles work.?
?I select the locomotive and throttle up but nothing happens.

Re: Using a Large Number of Connections to JMRI
I'm thinking about using Arduino Mega modules. These have 54 I/O ports available at a lower cost than CMRI hardware and also can be programmed to implement logic locally. The Ethernet connection only consumes 4 ports.
I may end up with an RS485 bus, but I still would like an answer my question if someone can supply that.
Thanks much,
Jerry

Re: Using a Large Number of Connections to JMRI
Jerry,
Why the high number of connections instead of being nodes on a bus? Given
the usual cost of interfaces for the connections, it adds up kind of fast
for most hardware.

Re: Using a Large Number of Connections to JMRI
Jerry,
Why multiple connections ? CMRI uses a piggyback connection for the RS232/485 communications buss. All you need is one comm port connection to accommodate any number of CMRI nodes. The system is designed for multiple nodes.
I used both DCC accessory decoders using a USB connector for my DCC system and a CMRI system with a SUSIC and 10 nodes all connected to one comm port adapter. I operate on several large layouts using CMRI and none requires more than one USB/RS232/485 adapter. I have designed systems using 7 Smini nodes (48 outputs and 24 inputs per Smini) which is smaller than some of the layouts I operate on. No need to use more than one comm port connection.
Most of the layouts I operate on use "scrapper" computers too old to use for modern high speed programs but quite capable of controlling signaling on large layouts without any noticeable delay in response time.
Have you had an opportunity to read any of the CMRI manuals yet or have you already purchased the hardware ? I strongly suggest you do that before trying the "multiple" connection project. It might save you money and time.
Regards, Nick Kulp? ?

HO/HOn3 vs OperationsPro
I have an HO/HOn3 layout and have successfully built trains for the narrow gauge portion of the layout. I¡¯m new to JMRI and do not have a strong computer background. I am now trying to integrate the standard gauge operations. Reading the manual, it looks like I need to build a second profile. Therein lies my problem. When I get to the Config profile screen it is not clear what needs to be done. I also can¡¯t find the profile for the narrow gauge. Any assistance the group can provide is greatly appreciated.

Re: Detection going crazy
Sounds like maybe your cab bus is underpowered? You mentioned adding boosters? But there is still only one command station and unless I¡¯m mistaken that is the only source of power unless there are additional ¡°wall wart¡± type power supplies added to the cab bus at various plug in points.?
Also watch out for cab address 63 for AIU¡¯s as have found that to cause erratic updates or no updates to the cab bus clock.?

Re: Decoder Pro returns 123 for all decoder settings
... and upgrade to 4.12 - what you're encountering is a typical 4.10 problem, and it will happen again (and again).

Today the problem is that when trying to read values from a decoder, DP returns the value of 123 for all fields/all pages. Have verified that LocoBuffer-USB is installed correctly. The decoders (multiple) operate properly on the MAIN, all functions. So I think I have eliminated the decoders and LocoBuffer-USB as the problem.
