Hello I'm very new here and am just looking for some help I've purchased some laisdcc 21 pin decoders to run in my locos as they're much cheaper, but my Hornby select (1.5 firmware) doesn't appear to be to work with them. It seems like the chip correctly registers the loco address (set to 03) but when I try to make the loco move or operate it's functions it doesn't work. Does anybody know why or have a solution for this? Many thanks
