Hi GoingUnderground,
Thanks for your reply. Sorry i was not clear enough, The ECoS is the 50210, bought in 2017.
The only issue is your second point, it will not auto register locos with railcom fitted decoders, however it did up until a couple of months ago, for example I purchased a Hattons sound fitted 66 and it auto registered it, I then purchased another and it did not. I also have the new Bachman 158 with plux22 decoder, and again failed to recognise it. I have checked that railcom is enabled, and downloaded the latest firmware, I will check the decoder CV's as your suggestion. Also there used to by a 'railcom' symbol on the screen when running a loco with railcom I think, that no longer comes up of course.
It's not a massive issue, just an annoyance really, but it would be good to find out why it has stopped working, if possible,
Thanks
Reggie.
