DCS remote commander

Yes, a remote will control any commander in its Infrared path.  While generally line-of-sight, if you have light colored wall or ceilings I've notice the IR signal will bounce/reflect quite well actually!  If you're experimenting, just watch the intended and/or unintended commander's green LED when you press a key on the remote; obviously if it blinks then it received the IR command.

I'm a bit confused on what you mean by 2 independent but connected loops.  Since the commander will send its track signal to any DCS engine on the track, I'm not clear on how 2 commanders can effect independent operation?

What I was trying to get at is whether 2 remote commanders can interfere with one another.  With 2 commanders each tied into its' own Z 1000 and sitting on a small control panel, is there a danger that the remote for the commander that is wired to loop 1 could control the loco on loop 2 due to the proximity of the two commanders on the control panel and inattention of the operator holding the remote.i.e. myself or grandchildren.

Bottom line - will one remote operate any commander in its line of sight.

Bottom line.  Yes.  One remote will operate any commander in its line of sight.

Don't short change what Stan is saying.  Even if you had on sensor in a black box so that only one DCS Remote command would catch the signal, if you have your track loops connected, the DCS signal will go to both tracks and all DCS engine on those tracks with factory resets would respond to the same command.  G
