Can DCS Explorer be run in a passive mode on a predominantly Legacy/TMCC layout?

I'd like to hear ideas about this as well.

No. The Explorer cannot be used passively. Because it derives all it’s power from the input transformer and does not have an AUX power just for the electronics.

The DCS Remote Commander can be set up to run your MTH engines in passive mode. I have one set up on my layout for the same reason. You don't get full functionality of your engines and can only run one at a time but it's better than nothing.

The remote is IR line of sight to the RC so it needs to be located appropriately. I added a switch to disconnect the signal from the layout when not in use.

I have a Cab 1L running the rest of the layout.

Thanks very much for the responses, guys.  It looks like I'll have to set up the TIU if I want to run the MTH locomotives, or put them on a separate, reserved loop if I want to use the Wifi DCS Explorer.

Have a great Christmas!
