as posted previously, we have moved on to a Gaugemaster unit with the WiFi... but- we have been having issues. The unit has a track output and a programming output. The programming is not connected to anything... Whilst running in the way few weeks two different locos have simply stopped dead in their tracks (excuse pun!) and refused to response to their primary loco address. On checking, both had defaulted to loco 3. One then continued as 3, the other a Bachmann class 47 with a 21 pin decoder decided to change back to its 4 digit number, then back to 3, then back again... The other loco is a Hornby 9f fitted with a Lens decoder. Both have run for a number of years on two other controllers on another layout with no issue... Dad emailed Gaugemaster to query with them, and as expected, it couldn’t possibly be their unit fault. So... what’s people’s thoughts here? The 47 is plug and play decoder, the 9F is hard wired. They asked if I had set up a secondary address on the decoder, maybe a consist address, but as I use decoder pro and never used consists, I’m not sure that applies?
