If I run a jumpers to the variable track input that would power the input side.
Correct.
If I wire the track leads to the center of a double pole double throw switch, and then run the dcs to one side of the dpdt switch, and the variable track output to the other side of the dpdt switch, then I think that will do it without frying anything or creating any type of feed back loop. Can someone please confirm this for me?
That's not necessary. You just need to wire the output of the TIU's Variable Channel directly to the tracks.
When you want to operate your DCS engines in Command mode:
- Press TR
- Select Variable 1
- Roll the thumbwheel to 18 volts
- Press ENG
- Run your DCS engines.
When you want to run in conventional using non-DCS engines:
- Press TR
- Select Variable 1
- Use the thumbwheel to control voltage.
If you want to run conventional, including running your DCS engines as conventional engines:
- Press Menu/System/DCS Setup and press the AOF soft key to turn the DCS signal off for all channels
- Press TR
- Select Variable 1
- Use the thumbwheel to control voltage.
When you're done:
- Press TR
- Select Variable 1
- Roll the thumbwheel to 0 volts or press TVZ
- Press Menu/System/DCS Setup and press the AON soft key to turn the DCS signal back on for all channels.
This and a whole lot more is all in MTH’s “The DCS O Gauge Companion 2nd Edition", available for purchase as an eBook or a printed book at MTH's web store!
So i am doing this kinda in reverse want to be sure it is okay
I have it powered by aux power
input to variable1 out put to variable 1
turn power on z4000 via throttle to 18
use menu/system/dcs setup and FXD to toggle between fixed when running in command and variable when running conventional so only worry about the volts when running in conventional. turn voltage to zero and go back to running DCS
the step I have been missing is the AOF and AON button turning on and off the DCS signal
