RMweb Gold Phil Bullock Posted February 14, 2016 RMweb Gold Share Posted February 14, 2016 Looking for some help or advice please Have a sound chip which is assumed to be a loksound V3.5 - ex Bachmann sound 37 - which returns random Cv values using ECoS in programme track mode Doesn't seem to matter which CV I look at - have tried to trigger reset with 08 in CV 08 but to no gain..chip reads as generic NMRA 35 function if read Chip is installed in a loco which is fine and dandy with another v3.5 loksound in it and also behaves just the same in another loco Is there a fix for this I wonder? Many thanks in advance Phil Link to post Share on other sites More sharing options...
HLT 0109 Posted February 14, 2016 Share Posted February 14, 2016 I too should be interested in reading responses to this query; I have a Bachmann Class 25, factory fitted with sound (presumably on a Loksound v3.5) and I get the same problem when trying to read the CVs on Power Cab in Programming Track mode. The loco performs perfectly otherwise but I know that I will never be able to trust the CV readout. Conversely, My Bachmann class 37 of same specification does not suffer from this problem. Harold.

RMweb Gold Phil Bullock Posted February 15, 2016 Author RMweb Gold Share Posted February 15, 2016 Hi Harold Am now sending mine to Brian at Howes for a full reprogramme - will let you know if that cures the problem Kind regards Phil Link to post Share on other sites More sharing options...
RMweb Gold Mick Bonwick Posted February 15, 2016 RMweb Gold Share Posted February 15, 2016 I have experienced similar problems several times in the past, all with LokSound v3.5 decoders. With the first offender I did a factory reset 3 times in succession and the problem disappeared - everything went back to factory default. On 2 other occasions this failed, but I did succeed by using the programming track to set CV1 to 3, CV17 to 0 and CV18 to 0, in other words forcing a short address of 3. You could try these processes if it happens again in the future. My DCC system is Digitrax and I also use a SPROG and I can't remember which of them I used to change the CV values, but I wouldn't think there would be any difference with other systems.

Martin_R Posted February 17, 2016 Share Posted February 17, 2016 Hi Harold Am now sending mine to Brian at Howes for a full reprogramme - will let you know if that cures the problem Kind regards Phil I dropped my Class 20 off at Howes, Kiddlington Monday lunchtime for a re-blow - the Bachmann sound was just awful. Just been delivered back to me care of FedEx. Just given it a test run and now sounds and drives like a Class 20. Brilliant service! May be able to pop into DCC Supplies for a better speaker later this week. Link to post Share on other sites More sharing options...
RMweb Gold Phil Bullock Posted February 17, 2016 Author RMweb Gold Share Posted February 17, 2016 Thats good to hear Plenty of Howes 20s on Abbotswood, theres a rather large train on the youtube videos.... Dont forget that its the seperation of the sound paths from the front and rear of the speaker that plays a huge part in determining sound quality - just sealing around the speaker with blu tak or black mastic can make a huge difference.... Wont have mine back for a week or so as several locos so prefer to call and collect Phil Link to post Share on other sites More sharing options...
RMweb Gold pheaton Posted February 17, 2016 RMweb Gold Share Posted February 17, 2016 what version of ECoS firmware phil? normally a decoder returning duff info is interference or poor comms, my Hornby elite used to return nonsense occasionally but ive not seen anything on my ECoS... ive pm'd you about using my lokprogrammer by the way. Thanks Simon Link to post Share on other sites More sharing options...
Lady_Ava_Hay Posted February 18, 2016 Share Posted February 18, 2016 Very often these failures to get a decoder to accept valid commands are because the voltage used by the programmer needs tweaking up a bit. I use a variable bench supply transformer and I found that 14volts DC was better than 12volts DC when using a Lokprogrammer even for the standard CVs. Having said that, I seem to recall that the SPROG will also accept a similar higher voltage although I would query it with SPROG first. Link to post Share on other sites More sharing options...
