Bob,
If I run power through any of the the other terminals (individually), the TIU does not turn on (no red led and it cannot be found through the 'READ' button. I have not tried an external power supply and the track does receive power when I connect to Variable 2.
That's how the TIU is supposed to work.
In order to provide a DCS signal on any channel, a TIU must be receiving power via either the Aux. Power port (preferred) or Fixed Channel #1 Input. The USB port on a Rev. L TIU will also power the TIU, however, it will not power the DCS signal generators.
You might consider purchasing a copy of The DCS Companion 3rd Edition. You'll find it helpful in better understanding how DCS works and what are all of its capabilities..
This and a whole lot more is all in “The DCS Companion 3rd Edition!" This book is available from many fine OGR advertisers and forum sponsors, or as an eBook or a printed book at OGR’s web store! |
