TIU Variable Channel

Is there a way to just turn on the system and have all six variable channels be "ON" at set voltage(s) ?

Almost, if you're using DCS 4.30.

Instead of selecting each TIU Track individually, instead press the ALL softly on the TR screen and then select ALL TIU TRACKS. That will take you to a track control screen where you use the thumbwheel as a throttle for all of the TIU tracks together.

If you aren't on DCS 4.30, you can do the same thing except that the tracks will all come up at 18 volts every time you sroll up from zero.

Alternately, you can set each Variable channel to fixed mode. Then, when you power on thew layout, power will immediately pas straight through the TIU to the tracks for all 6 channels. When you want tho operate conventionally, just change the channels back to variable mode. This is discussed on page 45 of The DCS O Gauge Companion 2nd Edition.

Thanks for the info Barry !!!  I'll check my DCS revision, I know I'm at least one rev behind.  I'll be upgrading.  This is exactly what I was hoping for.   I still haven't figured out how to do block/collision avoidance in the command control mode ?  Any advise on present or future DCS capability ?

Any advise on present or future DCS capability ?

Just say tuned...
