RMweb Gold traction Posted October 21, 2012 RMweb Gold Share Posted October 21, 2012 I've had one of these decoders fitted to a Farish Class 08. Has anybody had a play with one, it's running a bit crap and just wanted to know if anybody had managed to get some good running out of one. Does anybody know where you can get an English version of the manual? Cheers Ian Link to post Share on other sites More sharing options...
Nigelcliffe Posted October 21, 2012 Share Posted October 21, 2012 Read my article on the 2mm Scale Association website on how to tune them. I rarely end up with the same settings in two nominally similar locos. Instructions in English, if they exist, they are even more inaccuate than the German ones. You could use the instructions for the DCX74 as the settings are the same, but with the caution that the English instructions have more inaccuracies than the German. - Nigel Link to post Share on other sites More sharing options...
RMweb Premium Izzy Posted October 22, 2012 RMweb Premium Share Posted October 22, 2012 I've got a DCX76 (virtually same as DCX75 as far as I know) runnning a Farish 08 on default settings - apart from adding a small amount of acceleration/deceleration - and it's fine. All the latest spec can motor Farish seem like this with current CT/Zimo chips, either of which easily give the best loco performance of any decoder makes in N/2mm. It's the older open frame motor types that seem to need tweaking most. Maybe the settings got altered during installation and a re-set to default values would be of benefit.

RMweb Premium Steven B Posted October 22, 2012 RMweb Premium Share Posted October 22, 2012 When you say it's running bady (this is a family site!), are you sure the conversion hasn't caused problems with the electrical pick-up. It took me quite a bit of fiddling to get mine running well after instaling a DCX75. Might be worth checking the mechanics and electrics before tinkering with the decoder. Happy modelling. Steven B.

Steven B. ditto to the above, it is worth noting that quite a few farish 04,08 and 14 chassis come out the box with badly adjusted wipers on the wheels, mine had 2 wipers waving in thin air and wasn't the worlds greatest runner on DC. when i chipped it i took the time to tweek the wipers so they all touched on full deflection of the axles both ways and it runs a charm now. you also have to be sure that the track and wheels are clean too as very little dirt can upset things.

RMweb Gold traction Posted October 23, 2012 Author RMweb Gold Share Posted October 23, 2012 Thanks all, Digitrains did the conversion, and the wheels, track and everything else is clean. The pick ups all look fine. Running it on a rolling road it looks like it wobbles as it's running, so could be something mechanical. I did try a decoder reset but still runs a bit ropey. I've always had to adjust settings on CT decoders, never had one that runs straight from the box. Thanks Nigel when I get back home I will follow your instructions and see what happens. Cheers all Ian Link to post Share on other sites More sharing options...
Nigelcliffe Posted October 23, 2012 Share Posted October 23, 2012 If you have a rolling road, you can test pickup easily on each axle by putting paper insulation between track and rollers. That should show up any issues. Decoders can't fix mechanical issues. I assume you know that CT use a non-standard reset method with CV1.

RMweb Gold RedgateModels Posted November 10, 2018 RMweb Gold Share Posted November 10, 2018 Has anyone had trouble with this decoder with the 2 digit address being linked to cv29? It's driving me mad! How do I reset? Link to post Share on other sites More sharing options...
Nigelcliffe Posted November 10, 2018 Share Posted November 10, 2018 Don't understand your question ? Unless you've accidentally put the loco in a consist on CV19 and can't work out what's happening ? Decoder reset is done by programming CV1=0 Link to post Share on other sites More sharing options...
RMweb Gold RedgateModels Posted November 10, 2018 RMweb Gold Share Posted November 10, 2018 Thinks it's down to the decoder not liking paged mode, there's a thread on another forum that Ian W started about this decoder. It'll do a reset then see tomorrow Link to post Share on other sites More sharing options...
RMweb Gold RedgateModels Posted November 10, 2018 RMweb Gold Share Posted November 10, 2018 Basically what happened, programming track on powercab, set decoder address to 13, loco ran wrong way. Went to check cv29 and it was 13! Link to post Share on other sites More sharing options...
Paul80 Posted November 10, 2018 Share Posted November 10, 2018 Hi I use the DCX76 in mine and it initially was rubbish, with very rough running, the issue for me was eventually resolved by following someone's advice to remove the PCB on the end of the motor and wire it direct, the PCB has smd capacitors on it that can give issues. 're your other problem I also have something similar with them, if I try to change one of the CV's as soon as I press enter what ever number I was adding ie changing CV5 to 128, CV1 would also change to 128 and it would also lock the decoder so I couldn't change any thing back, this is when using my Gaugemaster Prodigy Advance2 I now only adjust the settings using DecoderPro through a sprog3, no other decoder gives this issue but all 4 dcx76's do. I try not to use them any more but their small size sometimes makes them the obvious choice. I am now running two of my Farish 08's with Zimo decoders now and the results are so much better but a lot of work needs to be done to get them in, but after fitting sound in one the non sound one was a dodle, and it now has a 6pin plug for easy decoder changes.

RMweb Gold RedgateModels Posted November 11, 2018 RMweb Gold Share Posted November 11, 2018 Direct mode sorted it, for some reason with paged mode loads of cvs were getting written at the same time when altering cv29 etc. I'll have to stress to the customer to use direct mode if he wants to make changes in future. The decoder was his choice... Link to post Share on other sites More sharing options...
Nigelcliffe Posted November 11, 2018 Share Posted November 11, 2018 To be fair, the CT manual does say "direct mode" for programming.... Not that everyone bothers to read the manual. Link to post Share on other sites More sharing options...
Crosland Posted November 11, 2018 Share Posted November 11, 2018 To be fair, the CT manual does say "direct mode" for programming.... Not that everyone bothers to read the manual. It shouldn't screw up like that with paged mode but, I have to ask, who uses paged mode these days? Link to post Share on other sites More sharing options...
RMweb Gold RedgateModels Posted November 12, 2018 RMweb Gold Share Posted November 12, 2018 Well, my Powercab uses it by default and it's a bit clunky(er) programming in direct mode. As I said, I'll explain to the owner of the loco when I hand it over at Warley This thread on another site started by our very own Traction was what brought the issue to my attention https://www.modelrailforum.com/forums/index.php?showtopic=5550 Link to post Share on other sites More sharing options...
