mjcbasingsto Posted September 21, 2014 Share Posted September 21, 2014 I have just received my DoG TTS loco and have a question for anyone out there who has bought this loco. Do you get engine chuff in reverse because I certainly dont. Is it my decoder or is this a problem with the programming?Would be interested to hear from DoG TTS owners.Thanks Link to comment Share on other sites More sharing options...
Cronan Posted September 21, 2014 Share Posted September 21, 2014 Hi welcome to the forums. Someone has asked a similar question on another thread you might get some answers on. Here is the link https://www.hornby.com/forum/tts-sound-engines-released/?p=1 if this link doesn't work it's the thread called TTS sound engines released.

mjcbasingsto Posted September 21, 2014 Author Share Posted September 21, 2014 Hi I have checked the forum listed but this did not help. However things have moved on since my post. Having run the loco in on a rolling road. I put it on my dcc layout to adjust the CVs. I changed the address to 71 and although I could start the sound the loco would not respond. I set the back to 03 and every thing worked fine. It would appear there is a problem with the decoder not recognising any address other than 03. I will get in touch with Hornby. Thanks again.

96RAF Posted September 21, 2014 Share Posted September 21, 2014 Chuff and all other sounds works in both directions providing F1 is on and F17 hasn't been toggled to coast, but there is a lag (adjustable) between starting the loco when TTS will blow steam before moving off. You can reset the sound part of the decoder by writing value 5 to CV8. Link to comment Share on other sites More sharing options...
mjcbasingsto Posted September 22, 2014 Author Share Posted September 22, 2014 Hi,Things have moved on a little. I have reset the decoder (CV8 data 8) numerous times and have now resolved the issues regarding the decoder not recognising address 71 regarding movement. The current situation is the I can get a reverse chuff but only if I set my Prodigy Advance to 128 Steps. It does not chuff if set to 14 or 28 steps.

poliss Posted September 22, 2014 Share Posted September 22, 2014 Is there a specific reason why you're using 14 or 28 speed steps? Do your other locos have very old decoders that can't use 128 speed steps? Link to comment Share on other sites More sharing options...
96RAF Posted September 22, 2014 Share Posted September 22, 2014 I think the answer lies in 'Prodigy Advance' not Hornby... Link to comment Share on other sites More sharing options...
poliss Posted September 22, 2014 Share Posted September 22, 2014 Why would that be RAF? An NMRA Compliant DCC decoder should work with any brand of NMRA Compliant DCC controller.That's the whole point of the NMRA DCC standards. The Select is not NMRA compliant.

walkingthedog Posted September 22, 2014 Share Posted September 22, 2014 I think he's saying the Prodigy isn't coping not the decoder. The Prodigy doesn't default to 128. Link to comment Share on other sites More sharing options...
96RAF Posted September 23, 2014 Share Posted September 23, 2014 Correct WTDWithout knowing the controller up front your mind set automatically looks for Hornby related problems and fixes.Knowing Prodigy is the controller the answer then becomes obvious quicker.

walkingthedog Posted September 23, 2014 Share Posted September 23, 2014 And I don't have a clue what 128 means but I could see what you were saying RAF. Link to comment Share on other sites More sharing options...
Fishmanoz Posted September 23, 2014 Share Posted September 23, 2014 128 is the highest option for speed steps in the NMRA spec. Far from coincidentally, it is also 2 to the power 7 so a convenient maximum for a digital 8 bit word. Link to comment Share on other sites More sharing options...
walkingthedog Posted September 23, 2014 Share Posted September 23, 2014 Thank you Fishy. Helpful as ever. Link to comment Share on other sites More sharing options...
poliss Posted September 23, 2014 Share Posted September 23, 2014 It is a Hornby problem. The sound doesn't work, in reverse, when the decoder is set to 14 or 28 speed steps.Is it mentioned in the instructions? From the reply by Hornby, it doesn't seem so.I would suggest upgrading to a modern DCC controller that does more things. Link to comment Share on other sites More sharing options...
Graskie Posted September 23, 2014 Share Posted September 23, 2014 Could have been a maximum of 256 options, Fishy, using the full value of 8 bits to the byte. That would probably not be necessary or desirable, however. Link to comment Share on other sites More sharing options...
Fishmanoz Posted September 23, 2014 Share Posted September 23, 2014 You're almost right Graskie, it's actually 255 (starts at 0 with all bits at 0 and ends at 255 with all bits 1, giving 256 different numbers). I wondered if anyone would ask this. The thing is you need 8 bits to get to 128 because 7 will only get to 127. Conventional to use 8 bits to a byte anyway and someone at NMRA must have decided 128 steps was more than enough. Enough rambling. Link to comment Share on other sites More sharing options...
gerard_bromley Posted October 10, 2014 Share Posted October 10, 2014 I am relativley new to railway modelling and I am looking at upgrading my contoller. I have researched several diffent types e.g. Prodigy but I find myself getting more and more confused and uncertain about the correct choice. I am at present using a Hornby Select with a 4 amp transformer driving several older type locos, 15 years old, all of them fitted with Hornby decoders fitted proffesionaly by my dealer.I am also running 3 new locos including the DoG TT loco. Total number of Locos 7.I have already discovered that the Select has limitations, typicaly I can only acces half the sound options on the DoG!Can you, or any on the forum, suggest an altrenative to the Select. I.e. Is the Elite ok or would you recommend another within the price range of the Elite, or indeed a cheaper controller. My layout is reasonable small and I dont envisage enlarging it in the near future. All advise gratefuly recieved. Link to comment Share on other sites More sharing options...
idlemarvel Posted October 10, 2014 Share Posted October 10, 2014 Hi Gerard,This forum by its nature can only give you advice on hornby offerings. As you have discovered select has its limitations, particularly evident with sound fitted locos. The hornby options are the elite which is excellent and will do anything and everything you want (including playing sounds and functions F0 to F28), or an elink but that requires software (railmaster) and a laptop. If you are not computer literate and don't have a spare laptop then go for the elite, the elite will work by itself and does not preclude you going to computer control with railmaster in the future. Also the learning curve on the elite is quite small if you know the select. If you are computer literate and fancy going down the road of computer control, elink+railmaster is much cheaper, less than half the price of elite, but the learning curve will be high compared to what you are used to with the select.

gerard_bromley Posted October 11, 2014 Share Posted October 11, 2014 Hi idemarvel,Many thanks for the advise.I have all thats required to use railmaster but I'm content at the moment to follow your advise and upgrade to Elite, not least because my layout is far from finished and I don't want to spend to much time on going through the learning curve with railmaster. I would rather spend the time building the layout and running my locos. I will look at running on railmaster when I have completed all the hard wiring and interfacing required to fully automate the layout. Thanks Link to comment Share on other sites More sharing options...
Graskie Posted October 11, 2014 Share Posted October 11, 2014 I think you've come to a very sensible conclusion, Gerard. I started with an Elite which, as has been said, is far more versatile than the Select, no matter how many amps you have with the latter. RM wasn't available when I bought my Elite but nevertheless was able to be employed in conjunction with it when it did appear. I still sometimes run my layout with just the Elite, or even in addition to RM. It's a combination I never regret having. You can learn a lot from the Elite on its own before going computerised, such as reading and writing CVs, and it is, of course, NMRA compliant, whereas the Select is not.

RDS Posted October 11, 2014 Share Posted October 11, 2014 GerardI totally agree with Graskie and that is exactly the system I use as well. The upgrade to Elite will help a lot and you can then go to RailMaster (which I would fully recommend) and it would make your 7 Loco's a lot easier to control.It would also make it possible, if you wish, to just sit back and watch them operate themselves under computer control, which I must admit, I find fascinating.
