Matt,
The Manual says to "slave" the other WIU's to one WIU, but in testing, communication with the locomotive was lost when it moved from one TIU zone to another.
That should be expected. It works just like a remote in Normal TIU Mode.. The DCS engine is only associated with one TIU and, when it leaves that TIU's domain, just like with the remote no other TIU is sent commands from the app.
