    Hattons DCC Decoders

    in DCC Discussion Topics (not questions)

    I think you've discovered that "cheap" isn't always going to be reliable or quality.  No CV changes, and certainly not an attempt to reset, should result in an uncontrollable decoder. 

     

    Three choices I think;   ( a )  send it back to supplier for replacement or refund,  or  ( b )  leave it on one side for several days (possibly also a night in the fridge, though let it warm up gently to room temp afterwards) and then see if its recovered its marbles and works again,    ( c ) chuck it in the bin and buy something which isn't flakey.

    Thanks Nigel

     

    I think you may be right about cheap quality! It seems there is a reoccurring problem with at least one batch that CV8=8 is not resetting to default

     

    Night in the fridge seems quite a good idea but I think it'll be going for a trip back to Hattons to see if we can get a possible replacement.

     

    This said however I think I would risk buying these again as at such low prices you can almost afford to loose a few

    I have a Hattons 21 pin decoder operating with the Gaugemaster Prodigy Express.

     

    Great controller so far, only thing is f2 is designed for the horn and so the controller button has to be held down to keep it on. As any locos I will be running this decoder in will most likely have aux2 connected to some form of lighting, I decided to change this in the CV's to be operated by f3.

     

    Seemed simple enough however upon doing this the decoder has become completely unresponsive. Thinking I'd messed up I attempted to set CV 8 to 8 to restore default settings but with no change what so ever. The loco will sit on the main line with all lights on and ignore the controller like it's not there.

     

    The address is 3 as new and never changed so I don't think that's wrong...

     

    Just to add to the mystery I tried to read the cv values from the programming track and the loco just drove off returning error on the controller! Although I now understand these decoders can't be read?

    Aux 2 has been disconnected from the PCB as suggested above with no change...

     

    So...can anyone tell me what on earth I've done to it?
