So glad for this forum. Mine acted up like the original post for the first time. Never did that before. Would just reboot the unit and the light would change to purple. And as others have mentioned, reset button didn't solve the issue either (and yes I have the latest firmware).
So I did the "add engine" command as explained above and , ta-daa, light goes to purple and everything works.
My single biggest complaint with the DSCS explorer is the manual. It is woefully inadequate for first time users and yet they are including it in starter sets. (And double checked the version on the MTH site before posting this). Anyone else besides me see an issue there?
No faster way to drive people away that to make it to difficult for them to solve what turns out to be a simple problem.
Having a well thought out troubleshooting section and a full explanation of the lights would be a decent start. Would only add one page at most to do so (might even only fill in the rest of the troubleshooting page). The manual does not mention ANY of the following
1. the 5 sec blinking red with a short
2. forcing a signal to the track if the light is a steady red and all track problems have been sorted by using add engine
3. that a steady red light can also mean track power is off due to a safety trip,
4. that a reset will not always solve the track connection issue,
5. that NO connection to the track will also cause a red light. All they say is "overloaded track"
5. the lights and sound on any locomotive will be off, even with power to the track until you start up the locomotive, (nice note for those going from conventional to DCS)
They assume everything will be hunky dory electrically and spend more time on the app and LuCi than helping the owner with any possible issue. I've heard about a supposed update to the pdf manual for over a year and . . . nothing. Seriously, this would be one of the easiest changes to make that would go a LONG way in having satisfied customers. Yet, MTH seems to not care.
It seems customer service / relations in the O gauge section of the industry by Lionel and MTH has gone down the tubes in the last decade. Sad, as I've seen phenomenal service from other manufacturers in other scales.
