Sudden No Engine To Add Difficulty

There were issues adding engines with early DCS 4.0x releases prior to 4.10. A usually effective workaround was to tether the remote to the TIU by connecting a 4-conductor telephone handset cable (the curly one) between the TIU's Remote Input port and the base of the remote.

A permanent fix was to upgrade to DCS 4.10 or 4.20.

This and a whole lot more is all in MTH’s “The DCS O Gauge Companion 2nd Edition", available for purchase as an eBook or a printed book at MTH's web store!

Barry, 

Thanks. GOod to know it is a bug in the system. With 10s all the way around, a very basic, small loop, and clean track, I couldn't think of anything else that would cause this. My previous layout never had problems adding to the remote but the layout before that, less complicated than the most recent one, also had major issues adding engines to the remote but everything ran fine. Glad to know it is in the software and there is a fix for it. I'll get a phone cord as I'm not planning to remove the TIU anytime soon. 

Barry, 

Been doing some research online and it seems as if the 4.01 problem that was corrected in the following update (4.02?) was more focused on lashups (I don't do lashups) as opposed to adding individual engines to the remotes. Is this accurate? 

Is this accurate?

No, not as far as I recall.
