CTG.Bearhouse Posted January 4, 2014 Share Posted January 4, 2014 I have just purchased elink / railmaster and find it very confusing in what order I should set up a loco and how to actually save the cv settings. I also may have a faulty decoder as when I fitted it to a new DC ready loco It will not run on an analogue layout. However if I refit the blanking plug it will run ok on an analogue layout Any thoughts anyone? CG Link to comment Share on other sites More sharing options...
stephenknicholson Posted January 4, 2014 Share Posted January 4, 2014 Decoders have a setting to enable/disable the ability to run on analogue. Read the value that cv 29 is set to. If its anything other than 6 or 38 then Analogue running is probably disabled. I found this with a recently purchased Bachmann decoder. This is a complex setting so its best to make use of calculator to ensure the correct setting. Search for "DCC CV29 Calculator". If you have a short address (ie 2 digits) the value "6" will normally be fine. If you have a long address then I think "38" will do the trick.

stephenknicholson Posted January 4, 2014 Share Posted January 4, 2014 I posted a comprehensive reply but its held for moderation! Its possible that the decoder has analogue disabled - but this can be changed. Link to comment Share on other sites More sharing options...
Fishmanoz Posted January 4, 2014 Share Posted January 4, 2014 Hi CTG.Bh, welcome to the forums and while Stephen sorts out his post, take a look at https://www.hornby.com/forums/hornby-forums/hornby-railmaster/5777/ near the bottom of the page at the HRMS post which restates what is already in the manual. Then if you want to program a long ID, go to page 6 of the same thread where HRMS cover that. Let us know if still unclear. And Stephen is right about analog running, it is set on or off in CV29 and is covered in the manual. Note it is recommended to be off as you can get high speed runaways with it turned on.

Graskie Posted January 4, 2014 Share Posted January 4, 2014 It probably needs someone like WTD DC to confirm this, but to run a DCC fitted loco on DC (analogue) track, you do need to reinsert the blanking plate. You can run the loco in analogue mode on a DCC layout with the decoder fitted and the appropriate change to CV29, as mentioned above, but it is not advisable, as you could damage the decoder. See other threads concerning this danger. Link to comment Share on other sites More sharing options...
Fishmanoz Posted January 4, 2014 Share Posted January 4, 2014 It is ok to run DCC on DC without damage to anything, Graskie. WTD reports his DCC friends running their locos this way. The problem is that, with this mode enabled, you can get full speed runaways. This occurs when a decoder gets an imperfect DCC signal, interprets it to be analog, and so switches to DC mode. Now with DCC applying full volts to the track,the loco takes off at full speed and can only be stopped by removing the supply. Because of this, it is recommended DC mode be switched off in CV29. The opposite, running a DC loco on DCC using address 00 is certainly not recommended as it can cause your motor to burn out, particularly if left standing still on the track.

Fishmanoz Posted January 4, 2014 Share Posted January 4, 2014 To turn off DC operation, subtract 4 from the decimal value of CV29. To turn it on, add 4. Only turn it on when you actually want to operate on a DC layout. Leave it off at all times on a DCC layout. Link to comment Share on other sites More sharing options...
CTG.Bearhouse Posted January 6, 2014 Author Share Posted January 6, 2014 Thanks for all the advice...I have actually sent the decoder back to Hornby so when I get the replacement I will start again! and let you know how I get on. CTG Link to comment Share on other sites More sharing options...
Fishmanoz Posted January 6, 2014 Share Posted January 6, 2014 No problem but note as above, not running on DC is not a fault, it is just a setting in CV29 which is easy to adjust once you get the hang of writing CVs. Link to comment Share on other sites More sharing options...
