SOLVED - Thanks to another forum, answer was to turn the power on and off again the PowerCab.

Hi, I'm not big into CVs etc so bear with me.

I've reset a couple of decoders using my NCE Powercab using 8 against CV8

Then gone to 'reprogramme' them. The decoder 'clicks' when you go through the various stages of Manufactuerers ID etc, recognises the numbers etc, but when you set the loco number and then select it, nothing happens, loco doesn't respond.

Any ideas welcomed.

I have set the Short and Long address and at the point where it asks 'Set Config' I've pressed Enter for No.

Could that be the issue?

Thanks

When you get to the Addresses, you need to decide whether you want to use the Short Address, or the Long address.  When you set the Addresses, you need to press No for the one you don't want to use and Yes for the one you do want to use.

Maybe silly, but you did set the address for the loco in CV1 didn't you?
I nearly ended up banging my head against the wall when the decoder asked for the loco address, went through everything and nothing worked unless I set the loco as '3', ESU decoder, booklet in tiny grey print in German and only in one place did it say set the loco address under CV1!

With the NCE Powercab, normally one does not enter loco number via CV's but as mentioned by Julian, you get asked in English what do you want to do and it then puts your answer into the decoder by updating CV's.

If you want to change which, address you use {long or short}, it is easy to change from long to short using CV 29. 

CV 29 sets a number of functions, like Forward / Reverse; Long / short Address; 14, 28/128 Speed Steps; DC decoder Operation [normally best off]; Railcom, on / off and Complex speed curves on / off. There is even a calculator which will do it for you and shows you the number to enter in CV 29. {click the link below} You will see that these numbers in column B double as you go down the column { 1, 2, 4, 8, 16, 32 you don't need to go any further }.  Each of these functions will change and by adding the numbers, you selected, together, you enter the result in CV29.  That sounds complicated, but in reality it is simple.  

http://www.2mm.org.uk/articles/cv29%20calculator.htm   You simply tick the boxes [Col C] next to the descriptions [Col D] and it will enter the number - or a 0 if you don't tick it, because you want the other option.  At the bottom of Column C is a calculation which added all the numbers you have ticked - and that is the number to enter into CV 29 in your decoder CVs.

eg. In the top Row, it will change Forward or Reverse options.  An un-ticked box will make the loco run in the direction your controller has selected, ticking the box will make the loco run the reverse to what you select on the controller,  A tick will add the number 1 into the CV number total.
If you look at the 6th Row down, you can see that the row is numbered "5", the Column B box to the right has the number 32, so 0 will give you the Short Address and adding in 32 will make the decoder respond to the Long Address.  The linked spreadsheet will do that for you, as you tick the little boxes.

***Quick Tip - given that the numbers double up and 32 is the largest - if the number already in CV29 is bigger than 32, you have the Long Address set, so if you would like the Short Address, subtract 32 from the number and enter the new number.  However, if the number already in CV29 is less than 32, you have the Short Address set, so if you would like the Long Address 32 should be added to the number already there and enter the new one.  

I hope this helps.

Regards
Julian

I've just read through Julian's post.  I'm now going for a lie down.
