Gerald,
Toggle must be done before TIU is powered, otherwise watchdog signal is lost and loco will start in conventional mode.
Not exactly.
From The DCS O Gauge Companion 2nd Edition, page 102:
Missing the Watchdog Signal
If individual PS2 engines miss seeing the watchdog signal, they can be either brought directly into DCS active mode by pressing the Start Up key or put into DCS stealth mode by pressing the Shut Down key. However, this is not the same for lashups.
If a lashup is powered on after the watchdog signal has come and gone, perhaps if its siding was toggled on after voltage appeared at the TIU channel outputs connected to its siding, there are two ways to put the lashup into DCS mode. One way to put the engine into DCS mode is to turn off power to the inputs for the TIU channel that is connected to the track upon which the lashup resides, toggle on the siding and then re-apply power. The other way is to first highlight the engine in the remote's Active or Inactive Engine list. Then, flip the toggle switch and immediately press the thumbwheel to select the engine. It will come up in DCS stealth mode, dark and silent. This also works with individual PS2 engines.
