Locomotives unable to change direction.

[email protected] All Messages By This Member #230949 Hi, I'll apologise now for not being very computer / DCC savvy. I recently installed a Digitrax DN163K1B in a Kato SD70ACe and it would only travel in one direction after programming. I thought there was a fault in the decoder and was trying to figure out what to do with it. ?Then my dad bought 3 used Kato locos with MRC sound decoders and asked me to change the loco numbers. ?Now all 4 locos will only travel one direction. 2 will only travel backwards and 2 will only travel forwards. I think it's too much of a coincidence to have 4 locos with the same errors. Additional to this the locos can be programmed when following the "New Loco" route but afterwards cannot be identified by Decoderpro. "Identify" results in Error 301 , no locomotive found. I've tried "Reset" but all that does is set the loco number to 3 and switch analog control to on. Any help would be appreciated please.

Please say exactly what equipment you are using.? ??

Inobu One All Messages By This Member #230955 The common denominator looks to be your programming. You could be writing the same configuration into each decoder. If you can see the address change back to 3 on a reset then you know the decoder is reading the Reset command. So you have good communication/programming to the decoder. What is odd is the 301 Error. That means that the Programmer is not electrically connected to the decoder (dirty track, bad connection) A good test is to reset the decoder and then try operating the loco with address 3. If you have both direction control then you know its the configuration you are writing to the decoder. The more information that you provide the easier it is to pin point the problem. Inobu
[email protected] All Messages By This Member #234712 I have a 2012 iMac with Java 8 and DecoderPro running version 4.26. ? I have a Digitrax PR4 attached to a programming track and I have a Sprog 2 attached to a second programming track. ? I would like to try to sort the Digitrax DN163K1B decoder first. ?I converted the loco back to DC and it runs fine in forward and reverse. ? ? When I install the DCC card, DN163K1B, the locomotive will only run forwards.?
whmvd All Messages By This Member #234715 So many questions! 1) How is this JMRI related? 2) Are you running it under DCC or DC power when it only wants to go in one direction? 3) What command station is active when you run the loco (so not on the program track)? 4) What throttle do you use to run it under DCC? 5) Does it run in both directions on DC (with DC enabled)? 6) What do the directional lights do? Probably more...

Peter Ulvestad All Messages By This Member #234716 The simple answer is the decoder is no good. Do you have another you can try in it's place. Maybe contact Digitrax directly and ask them. This appears to be a Digitrax issue and not JMRI. -- Peter Ulvestad JMRI Users Group Moderator ( ) Tam Valley Group Moderator ( ) Sprog-DCC Group Moderator ( ) Edmonton Model Railroad Association ( )
Morgan f Bilbo All Messages By This Member #234717 PeterU: I can agree with you about this not being a JMRI issue. But the OP did say he tried 3 MRC decoders. So, it's not the decoder either. It must be the way he programs them. As for a PR4 vs a SPROG. I'd prefer the SPROG. But since the original question refers to a "Digitrax DN163K1B in a Kato SD70ACe", then I'd choose the PR4. And Wouter: He did say it runs both directions on DC. Just MHO. l'm not criticizing anyone. Morgan Bilbo, JAVA/ZULU 11.52.13 jre, JMRI 5.4.
whmvd All Messages By This Member #234719 Morgan: yes, he did say it runs in both directions on DC, but that was without the decoder inside. Whether it runs in both directions on DC with the decoder in place (and programmed to enable DC running) is a whole different matter - and that was my question. But thanks for making the point, because it was too easy to misread.

Morgan f Bilbo All Messages By This Member #234721 Wouter: Thanks for clarifying. I must have missed that. I guess the main thrust in this thread is: "Is this a JMRI matter". And that's where PeterU was correct. So what I refer to is that if the OP has trouble with a Digitrax and MRC decoders, it isn't with the decoder/and now, not JMRI. It's something else.

whmvd All Messages By This Member #234725 Morgan, I'd agree with that, but I'd still like the answers to the questions. The decoder coud certaily be fulty - most likely problem, even. But it could also be something as simple as normally operating with a standard DC controller, and now finding that the DCC throttle is not, as expected, in yard mode. That would be very simple. Still not JMRI, though! :-) But based on what we actually know, guesswork is pointless.

Ken Cameron All Messages By This Member #234740 My suggestion would be to reset the decoder. That's the best way to remove any possible configuration issues being the cause. Granted I'm not thinking of any combo of configuration options that would prevent a decoder from running both ways. If you have a lot of configuration detail in the decoder, make sure you've read and saved that into the roster. That way if doing the reset actually worked, then we could review the settings and maybe find a cause if the reset configuration was fine. -Ken Cameron, Member JMRI Dev Team www.jmri.org www.fingerlakeslivesteamers.org www.cnymod.com
[email protected] All Messages By This Member #234741 Answers to your questions ...... ? 1. I posted my question in the Digitrax Users IO group and they sent me here.? ? 2. I have the DCC card installed and only try to run it as DCC , its at this time it will only run in one direction. ?I have not tried to run the loco on DC track with the DCC card installed. ?I removed the DCC card and installed a DC board in the loco and it runs both directions fine. I did this to check there was no mechanical fault. ?I have put the DCC card back in and it will only move in the one direction again. ? 3. I do not have a command station or layout to run on. I only have the two seperate test tracks. One track has a PR4 which is not able to let locomotives move forward or backwards, it only allows programming. The other track has the Sprog 2 where I program and am able to run the loco back or forwards.? ? 4. I don't have a seperate physical throttle. I only have the throttle on the DecoderPro programming screen. ? 5. I have not tried the loco on a DC track while it has a DCC card installed. ? 6. With a DCC card installed on DCC test track the lights change to the appropriate direction selected.
Mick Moignard All Messages By This Member #234756 开云体育 It sounds like the motor drive on the decoder for one direction has failed. ?Each direction has a seperate drive chip. ?
