The son of Triangman Posted August 17, 2023 Share Posted August 17, 2023 A simple jumper selector would be a decent simple solution to the programming issue, taking the stay alive out of circuit when programming. Link to comment Share on other sites More sharing options...
ColinB Posted August 18, 2023 Share Posted August 18, 2023 Yes but the problem is you have to take the loco apart to do it. Generally and I am not going to point fingers, the less times you take the loco apart the less bits fall off it. To me there should be an option to extend the programming time to allow the "stay alive" to charge up. I am sure there are reasons why not to do this, but it is a pain.

Yelrow Posted August 18, 2023 Share Posted August 18, 2023 Should this not be on a Stay Alive thread, rather than prices. Tis just if anyone want to research this in future, they will never look under Prices, and this is very important stuff. Link to comment Share on other sites More sharing options...
Rallymatt Posted August 18, 2023 Share Posted August 18, 2023 100% agree with Yelrow, this is very useful info and will be impossible to find via search (although I can never find anything via search other than most recent posts 🤣) Link to comment Share on other sites More sharing options...
ColinB Posted August 18, 2023 Share Posted August 18, 2023 I must admit that using an Elite as a programmer very many of the decoders with "stay alive" don't read, but I suppose some people are luckier than I am. I read the spec for programming and 100 mS is not really long enough time to charge a decent electrolytic capacitor, so it is not surprising. In fact when I used to design micro circuits I used to allow 100 mS before the micro came out of reset. So SteveM6 which decoders do you use and what is the capacitance value of your stay alive? I had most of my issues with the DCC Concepts ones but there were others. There have been many posts on the subject generally recommending that you remove the "stay alive" if you want to read CVs reliably on DCC. The link with prices was that I just said that YouChoos did a small "stay alive" circuit board. It was relatively cheap unless you added the high density computer grade "backup" capacitors.

96RAF Posted August 18, 2023 Share Posted August 18, 2023 There is a new thread per Yelrows suggestion in HM DCC (7000) section so please cut and paste your posts here over there.https://uk.hornby.com/community/forum/programming-a-stay-alive-equipped-decoder-364692?ccm_paging_p=1#end-of-repliesAny gash posts left will be binned after a few days.
