Dear JMRI Users,

I just joined the group and this is my first post. To all you WiThrottle-JMRI-Mac "gurus,"

I recently converted my N Scale layout from DC to DCC. I installed a Digitrax DSC240 Advance Command Station with Digitrax LNWI Loconet Wifi Interface.
I downloaded JMRI Panel Pro and Decoder Pro 4.10 Software and installed it on my MacBook Pro running OSX 10.10.2 Yosemite
I purchased, downloaded and installed WiThrottle on my iPad.
The Digitrax DSC240 Advance Command Station is connected to an isolated programming track per the manual. The WiThrottle is connected via the Digitrax LNWI Loconet Wifi Interface.

I'm having two issues:
1. I cannot program any locomotives on the isolated programming track.
The JMRI Decoder Pro software is giving me the prompt: "Programmer error. Programmer busy (302)" (See JPEG image below)
The WiThrottle JMRI webpage states:
302 — programmer busyThe command station has reported that it's busy doing something else, and can't do any programming right now.This usually means that some other part of the DCC system is doing a programming operation, e.g. a hand-held throttle.Some DCC systems can't do ops-mode programming (programming on the main) while also using the service mode programming track, in which case they'll return this error message.
I'm not doing any programming anywhere else on the layout.______________________

2. The WiThrottle will not allow me to change addresses.After entering address the address is displayed in "Recents." Once I've programmed an address, in this case 6035, when I try to enter the address a second time I get the prompt: "Loco 6035(L) In-Use Would you like to acquire this address?" When I click the YES button nothing happens, even with repeated pressing. When I click the NO button the window disappears, but the cycle repeats and remains NOT SET. I tried to delete the Roster addresses, It's like the WiThrottle gets "stuck."I also get the prompt "Unable to load JMRI WebServer page." It appears that the WiThrottle is not "seeing" the the server" (my MacBook Pro).See JPEG graphic below.

The PanelPro appears to "see" the WiThrottle in the "Advertising WiThrottle" window, but no device is showing the the Device Name window. The DecoderPro doesn't "see" the WiThrottle in the "Advertising WiThrottle" window, and no device is showing the the Device Name window. See JPEG graphics in photo section under WiThrottle and JMRI Questions.
I suspect these issues may be connected and may have to do with the drivers.

PLEASE ADVISE,Regards,Robert Diepenbrock

Is there a straightforward way to send a specific speed step (i.e. 0-28 or 0-126) instead of a throttle value 0.0 to 1.0 to a throttle? I can't seem to find a place in the code where it will let me do that... My apology in advance if this is a stupid question.

I'm using?jmri.jmrit.automat.AbstractAutomaton
...
self.throttle.setSpeedSetting(1.0)

Thanks,

-Erich

You need to shutoff verbal acknowledgement.

I recently bought an Atlas Trainmaster with a QSI decoder, Series 7.? I was able to reprogram the address and NMRA digital setting using DP 4.10.? However, when I tried to change sounds, volume or speed table, the decoder talked back to me but the changes never took.? I ended up using my NCE throttle to get the volumes adjusted but wondered if there is a known problem with DP tabs not working with the complex QSI CV settings?? I programmed the address on the program track and all the rest I tried on the main.

Bob,

Thanks so much for your reply. Thanks also for all your excellent work and leadership on JMRI. It's obviously being used and much appreciated by so many!!

Bob,

Did you verify that the "Preferences >> Defaults" entries are set to tLocoNet?

In Python, “None” is the “thing reference doesn’t point to anything” value that Java calls “null”.

Hi,
I have been working with sensor scripts of late and am in need of testing whether a sensor with a given
user name exists. I understand from the doc that for: s = sensors.getByUserName( uname )
sensors.getByUserName returns a null if uname is not a valid sensor user name.
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!
Have fun! :-)

OK, installed 4.12 and same problem. I have verified everything I can thing of. I ran the LocoBuffer-USB test noted on their website and it checks out. Could it be JAVA related? I have version 8.

What other things should I be checking. Thanks. Bob

Hi Wouter,

Thanks for that answer.?? if s :
Unfortunately it did not work.

I eventually found that:
if s is None :
did work correctly.

Have fun!? :-)
Best regards,
Geoff

OK 4.12 installed. Roster still there :)
I read entire CV Sheet and made sure all CV’s were read.

When I go to the “Function Map” tab some functions are indicated, others say things like AUX-1 or 3.?

I put the loco (still in the consist of the main and suede my NCE ProCab to select Function keys and I recorded what is on each key.

I still cannot find where I change volumes for the horn, bell or prime mover, nor can I find where to select sounds for things like the horn, bell, prime mover. ?I find only the Master Volume.

OK, ,glad to hear it's a known issue. Will do the upgrade and report back. Thanks. Bob

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.

I would like to know what the limitations are to using a large number of connections to JMRI. I'm looking at defining in the area of 10 CMRI connections using either USB or Ethernet to connect to Arduino modules. Each connection will have only a single node defined. I think this should give me enough I/O to build a signaling system for a fairly large layout. Is there a limit to the number of connections JMRI will handle? Are there other drawbacks to this approach such as response times?

Richard,

Check the Edit->Preferences->Defaults, make sure the options selected
LocoNet for all of them.
