DCS Explorer Wifi. Can it be used passively?

FYI Ron, this has been discussed in detail in another thread found here: https://ogrforum.com/...xplorer-passive-mode

It does appear there is a way to run the Explorer in Passive mode!

Reviewing the topic, it did not include all of the big picture of the schematic. You need to provide DCS isolation- an inductor in series with your AC track power source or transformer to prevent it as a source from attenuating the DCS signal.

So again, yes, you need that DCS isolation circuit at the DCS explorer output, that passes DCS signal- but prevents power (AC or DC) from backfeeding the MTH DCS exporer-

And

You need a 22uH inductor (with sufficient current rating) in series with your transformer to prevent that same DCS signal from being attenuated by your transformer being the power source.

I still don't see this as a "seamless" method when you have multiple explorers.  When the engine you're running leaves the track connected to the Explorer that you added it to, it will be out of control from your WiFi device.

Truthfully, if you have a big enough layout to use multiple DCS Explorers, just buy the new WTIU and do it right!

Very educational discussion in this and the referred thread.  I'm not as interested in fabrication of circuits as I once was so I think my DCS Explorer will be reserved for under the tree, away from the Legacy setup.  If I want to run one of my two MTH locos on the Legacy layout, I'll open my TIU and set it up.  Thanks to everyone who contributed.

Happy Thanksgiving.
