chris coates Posted December 12, 2018 Share Posted December 12, 2018 Hi. Hope this is the correct section for this. I have just purchased a Digitrax DCC controller for my O gauge diesel depot layout but it wont operate my Dapol 08's. When I check the loco address it comes back as correct but the loco doesn't run at all with this address. I also have a PIKO DCC controller for my main layout and everything works OK on this. I checked cv29 but all seemed ok. The Dapol is set for Railcom use but apart from this everything is as expected. I like the Digitrax unit as it's simply to use but why wont it work with the Dapol 08's?.....anyone help? Link to post Share on other sites More sharing options...
RMweb Premium Ray H Posted December 12, 2018 RMweb Premium Share Posted December 12, 2018 This isn't meant to be a silly question but does the Digitrax unit work with any other locos? Link to post Share on other sites More sharing options...
John ks Posted December 12, 2018 Share Posted December 12, 2018 (edited) Is there power to the track?. Digitrax can default to NO track power & it needs to be switched on. There should be a button marked "power" or "pwr." Pushing this button followed by the "+" or "-" key turns the power on or off. If I remember correctly Do other locos work on Digitrax Edit started typing this before I saw Ray H's reply What is the loco address? if it is a long address lower the 128(eg 0056 or 0003 etc) then it wont respond to Digitrax. Digitrax treats all addresses below 128 as short addresses If your loco is Long address 0028 & you type 0028 into Digitrax, Digitrax ignores the leading zeros & sends instructions to short address 28. Your loco wont respond to short address 28 because its waiting to respond to long address 0028 John Edited December 12, 2018 by John ks Link to post Share on other sites More sharing options...
RMweb Gold Oldddudders Posted December 12, 2018 RMweb Gold Share Posted December 12, 2018 Which throttle? Which command station? Link to post Share on other sites More sharing options...
RMweb Gold roundhouse Posted December 12, 2018 RMweb Gold Share Posted December 12, 2018 I have bought 2nd hand (with non factory fitted decoder) locos in the past and they did not work on my Digitrax system. I did a factory reset to the decoders then they started working so this may be worth a try. Link to post Share on other sites More sharing options...
chris coates Posted December 12, 2018 Author Share Posted December 12, 2018 Which throttle? Which command station? It's a Zephyr extra, model DCS51, with a PS314 power supply. I understand this is all I need for basic use? The unit works with my Heljan locos and also my Little loco one but with none of my two Dapol 08's That's a good point about the address's but the 08's are 3219 and 3358 so this isn't the problem I could try a reset but am open to other suggestions Link to post Share on other sites More sharing options...
RMweb Premium Ray H Posted December 12, 2018 RMweb Premium Share Posted December 12, 2018 On that basis I'd try a decoder rest first - but only on one loco until this can be resolved Link to post Share on other sites More sharing options...
chris coates Posted December 12, 2018 Author Share Posted December 12, 2018 On that basis I'd try a decoder rest first - but only on one loco until this can be resolved Thanks. Would you still do that even though the loco works perfectly OK on my PIKO DCC controller (as do all my dcc locos)? One odd thing happened when I just tried it. After no response with the 08 I added my 24 on the same track and changed loco to run to 5183. Although it started it wouldn't stop but kept moving slowly even though I had put the throttle to stop. I had to lift it off the track. I then took my 08 off and put my 24 back on and it ran OK (all DCC just in case of any query)....all very odd. I dont think the controller is faulty but there is definitely something wrong......help !! Link to post Share on other sites More sharing options...
RMweb Premium Ray H Posted December 12, 2018 RMweb Premium Share Posted December 12, 2018 I know it can be a pain but it might just be worth doing the reset - CV8 = 8 (usually). I'd try to do it using the Digitrax if that's possible. Link to post Share on other sites More sharing options...
peach james Posted December 12, 2018 Share Posted December 12, 2018 Try programming the address alone with the Digitrax system. I've had the same problem with NCE vs Digitrax, and reprogramming worked for me... James Link to post Share on other sites More sharing options...

The DCS51 is a very useful starter set, and can be expanded with boosters and throttles should you ever feel the need. Whatever the problem here, it is not about the command station capability.

chris coates Posted December 13, 2018 Author Share Posted December 13, 2018 Success my friends. For some reason both 08's 4 digit addresses had reverted to a single digit one. When I re-wrote the correct number all is fine. I shall now undertake some serious testing to make sure everything else is working fine Many thanks for your assistance Link to post Share on other sites More sharing options...
