Hi,

Are you sure that your servo is compatible with DCC++? A standard RC servo requires a pulse width modulated signal, which the arduino servo library will generate, if that's what you have used in your test sketch. ?I'm possibly wrong here but I suspect the DCC++ code just puts out a logic high or low depending on the turnout setting, which won't drive a standard RC servo.

Regards

Is it possible to add a column/field on the roster sheet for a consist address and have DP fill it in if the loco has a consist address. Thanks.

Bob? Here is an update to the above problem we discussed in Jan 2019.?
I replaced my new NCE box with the old Wangrow box. I now have control of the UNK OFF ON radio button.
Next I will upgrade the JMRI version. Suppose the NCE box was defective????
The one item I did not try was to replace the PS DB9 cable to computer w/ USB cable; as the cable does currently work but newer NCE might not like PS DB9???

BTW: will have a Asymmetric Stopping block module soon with 4 stopping block outputs, also an expansion board to add an additional 4 stopping blocks. You can go more in increments of 4 also.

do you have enough current available??? The servo draws ~ 150mA when it's moving.?? You can turn it off once it's had a chance to stabilize.?? You may want to put the servo on an auxiliary power supply.

Hello Group,

I have an Arduino Mega with motor shield running DCC++. I also have a Raspberry Pi running Steve Todd's image. I have upgraded JMRI on the RPi to v4.16 and Java 1.8.0_65. I have the letter "D" as the connection prefix in the JMRI connection preferences.

I have a servo connected directly to the Mega with 5V, GND, and PIN15 for control. I checked the wiring and have a good 5V going to the servo. I have created an entry in the JMRI turnout table with hardware address 115 (now shows as DT115) and chose "BSOUTPUT" in the Feedback Mode chooser. I then added an output to the DCC++ base station configuration with Index 115 assigned to PIN 15.

I built a quick panel with DT115, and this seems to work OK as the icon moves when clicked, I see "closed/thrown" in the turnout table and I see the Output Cmd "Output ID: 115 low/high" in the DCC++ traffic monitor, but the servo does not move. I have tested the servo by itself using an Arduino servo sketch and it works fine.

What have I missed?

Thanks for your help,

Richard

Hi Ken,

I recommend that you download the drivers for USB interface and reinstall them.???? I have found in the past that whenever Windows 10 installs updates the SILABS drivers have problems and need to be reinstalled.

Hello,

??

I have JMRI connected to my layout with an NCE USB interface. I have software for the interface using COMM4. Since originally installing JMRI, I updated my computer to Windows 10. When I try to start DecoderPro I get this message in a window: ???Unable to create connection "NCE2" (N2). ??Serial port COM4 is in use. Unable to run startup actions due to earlier failures.??? I believe I have deleted ???NCE2(N2). When I ignore message and continue to DecoderPro and select a locomotive the following error message appears at bottom of screen: ???Service mode program NCE is offline and Operator mode program NCE is offline???. I spoke with Ed at NCE today and he said problem is with JMRI and Windows 10.

What do I do? When I had Windows 7 Pro, I was able to set up 5 locomotives.

??

Thank you,

Before I do That I have done some more digging and I have discovered a number of car location problems. I want to clear them and see how it builds. This train has always been an easy build.

Jerry

Dave
Thank you for your help, and advice. Much appreciated.

Hi Jerry,

What does the build report say about the cars not being picked up.? If the build report isn't too long, you can copy and paste the entire report for us to review for you.

Dan

Brake on DC is very crude compared to Assymetric DCC. With Assymetric loco sounds still operate, and react with the changing speed of the engine as it slows and then accelerates. With brake on DC no DCC functions operate while on DC track.

Group:

Using Steve's RPi-JMRI distro for many months now on a couple of layouts killing power has not caused problems.

A possible warning is if the Pi is doing other things too, not just being Steve's JMRI machine, then there is a possibility that there is disk activity and the ?SD was being written to, then there could be corruption to the drive.

My Pi's are not running as a RR controller but rather as bullet proof WiFi access points where my friends are not opening their home net to strangers. Huge selling point... open house/guest session and the "hey can I use my phone?" Is a sure... server is RPi-JMRI password is rpI-jmri... Love it!

Off topic, sorta... Pi 4 looks to be producing Pi 3 bargains...

Jim Albanowski

I never had that problem with Brake on DC between blocks, or never noticed that.

My blocks where very long.


BTW: will have a Asymmetric Stopping block module soon with 4 stopping block outputs, also an expansion board to add an additional 4 stopping blocks. You can go more in increments of 4 also.

I am building a train with nine locations. In 3 of the locations the build does not pick up the car currently located at the location.
Therefore in those locations it places cars picked up from other locations served by this train, .
The build report does not indicate any problems with track length,
I have adjusted the initial move count.
I do notice that the reserves are high for these 3 locations than the other locations

I dont know what the experts do, but when I get a com port error starting JMRI in Windows 10 I edit the com port setting and restart JMRI.

Windows seems to change the com port arbitrarily when booting.

Phil:

the Condensed Code is a fantastic resource for operating on Western (West of the Alleghenys)?? TT&TO railroads! ALL serious operators should have a copy in their grip. ?? However, if you are modeling a prototype signal system you will find they were highly idiosyncratic (almost every Railroad did them a little differently) so it is very useful to find the appropriate rule book from your prototype (usually available on eBay for about $20 if you wait a while) and the era appropriate ETT which will usually have all the Special Instructions (and most of the unique -- shall we say funky? -- signals are addressed in the SIs).?? It is also handy to have as many photos as possible of signals on the subdivision(s) in question at the date being modeled.?? Think rivet counting on freight cars!?? Since you're going to do the work anyway, why not model the iconic and unique features of your prototype?

I looked up the little book ("Condensed Code of Operating Rules"), and it is available at the following link: .

Dennis,

Brake on DC is much more difficult to do properly because there will be a short circuit at the gaps between any DC brake section and a normal DCC section. This means that the DC should be supplied via a tail light lamp or other current limiter to adsorb the short as wheels and metal trucks cross the gaps. This is reduced if you switch the entire approach block to DC, but can still be an issue with long trains. (longer than a block) On the positive side I think all decoders will brake on DC if you turn off analog mode.

Asymmetric on the other hand does not cause any shorting at the gaps and needs no special protection nor separate power supply.

Dick :)
