From what I gather, you are speaking of prototype locos. I assume this is similar to an automatic transmission auto that, while in gear and idling, will not move when on an upgrade.

For a prototype diesel-electric loco:
- Idle: the diesel governor is set to keep the motor idling at rpm rate 1 of 8. The generator/alternator excitation is switched off so no electricity is being generated and the traction motors are doing nothing.
- Notch 1: the diesel governor is still set to keep the motor idling at rpm rate 1 of 8. However the generator/alternator excitation is switched on so some electrical pressure (voltage) is being generated and the traction motors will try to rotate. This may or may not happen, depending on brake/load/grade.
- Notch 2: the diesel governor is set to keep the motor idling at rpm rate 2 of 8. More electrical pressure (voltage) is being generated and the traction motors will try harder to rotate. This is more likely to happen, depending on brake/load/grade.

- Notch 8: the diesel governor is set to keep the motor idling at rpm rate 8 of 8. Maximum electrical pressure (voltage) is being generated and the traction motors will be applying a lot of force to the wheels. The motor current will be very great if the motor can't turn at the desired speed due to brake/load/grade and the motors will be getting very hot (possibly into the time-limited yellow or red zone of motor current). The motor current will decrease as the train gets up to speed due to BEMF being generated by the motor.

(That's pretty approximate and based on older DC generator/motor technology but you should get the idea.)

If so I will have to work on the VSD files and my decoder motor settings. All my n scale locos have been programmed to move on decoder step !. This means that whether lightly loaded or heavily loaded (many cars) they move on step ! (function of BEMF). Guess this is not prototypical.

Personally, I set my models to creep off very slowly at speed step 1, but with motor sound still at Idle. A high momentum setting in the decoder will delay move-off. That's about the closest you can get within the limitations of typical decoders.

I have made pretty good progress in the TMCC-2 command syntax. It is substantially different from TMCC1.?
The throttle needs the ability to select the appropriate setOpCode in order to set the first byte. This first byte lets
the base station know which command format is being used. TMCC-1 or TMCC-2.

As you switch between TMCC-1 to TMCC-2 the command set changes drastically. TMCC-2 has a 2 9 bit command bit syntax and 1 3 word command format. Because of this the JMRI throttle needs to allow the user to formulate the command via key strokes.

TMCC-1 and TMCC-2 need to have their own class and 3 system connections

3 System connections because Lionel has 3 base stations. TMCC, Cab1L and CAB2L.

TMCC only TMCC-1
Cab1L TMCC-1 and Limited TMCC-2
Cab2L TMCC-1 All TMCC-2

I'm trying to figure out the best way to organize the command list to roll into XML. From there is the GUI and then parsing itself. Hopefully I can get it to the point where the experts can evaluate what I have, fix my errors and make it an acceptable module.?

Might I request that you that you post the solution for others to peruse. It is often a lot easier to work from an example than from a discussion of what's in it.

Just a thought...

Thank you,

Klaus,

Thank you, thank you.? It worked perfectly.? notch 0 (idle) goes from step 0 to 0, notch 1 (run1) goes from step 1 to 12, and so on up to run8.

I did remove <idle-notch>1</idle-notch>.? ?Much success and a great sound.? The ALCO V16 251 is so different than the GE and EMD engines.

You could write Python scripts within JMRI to handle the connection with your database.

How often does your inventory change? The tricky part of a real-time connection is handling coordination and conflict.

From my research into JMRI, the "database" is a series of XML files. Is anyone aware of any sort of database interface that can be used in place of the XML? I've built my own application to track my inventory, pictures, etc. and would love to be able to tie in my inventory database directly with JMRI for operations. I understand it does import/export, but I'd prefer a real-time connection to a database. Thanks.

Does anyone have or know where there are more Locomotive sound files ready to use?? I look for sound files besides those already in JMRI.

i need help with marklin z engines, ?how can i clean and oil very old models that ran well for short period of time before being scored for at least 5 years and now wont move.
is there a place i can send them for repair.
please contact me directly rather than reply to this email

Rick,
My guess is that your older iPads do not support the WebSocket protocol. You can test this by going here on those devices:?
If your devices do not support WebSocket, the workaround is to use the older /frame server. You may need to enable it: Edit, Preferences, Web Server, Enable frames.
Then browse to ?here's mine for example:?

I don't follow what you're asking about the sizes. Sorry.

Idle and Run 1 have the same (Idle) RPM. the engine does not rev up until Run 2.

The motor might start turning in Run 1, depending on the load on the locomotive.

Thanks, I'll try it tomorrow

Hi Conrad,

Notch numbers must be unique within a VSD profile. The maximum number is not fixed.

The following example worked for me:
I took a diesel3 VSD file with 8 notches (1 to 8).
I added an idle sound as notch 0 (the audio format must match with the existing notch WAV files).
I did not declare <idle-notch> in config.xml.
Then I adjusted "next", "prev", "accel-limit" and "decel-limit" in notch 0 and notch 1.

<idle-notch> can be declared in a config.xml to assign a notch number as the idle sound. If <idle-notch> is not declared, VSD takes the lowest notch number as the idle sound.
I have never used <idle-notch> before and I think it's best to let VSD choose the right notch number.

You can do the offline download and install of Java 1.8 up to version 153 or
some number close to that. Somebody posted the correct number not too long
ago, which was the last version that installed ok on Win XP.

Leo,

And, to double-check - when you mention:

I can open the file and play it with no problem

Do you mean within JMRI or in software other than JMRI?

Thanks.

Best regards,

Leo,

That does not appear to be a file we ship in the JMRI distribution (despite it being located in the JMRI program directory).

(We recommend not adding user files within the JMRI program directory as these are at risk of removal during installation; rather add them to the user files location which, in your case would be a sub-directory of `C:\Users\Railroad\JMRI\`)

What is possible is that this .wav file is encoded using an audio codec that we do not support - we only support 8 and 16 bit PCM format wav files.

To verify, would it be possible to send a copy of the audio file such that I can double-check the codec used and run it through some debugging?

Thanks.

Best regards,

Matt H
