This is incredibly easy to do. It's in the instructions that come with the TIU.
1. Hook up the transformer you are using to either the Variable 1 or Variable 2 channel input. Connect the wires to the track to the Variable 1 or Variable 2 channel output.
2. Turn transformer throttle to full.
3. Hit the track button on the DCS remote. Select which ever channel the track is hooked up to (Variable 1 or Variable 2 channel).
4. Scroll the thumb wheel up. Voltage to the track increases or decreases if you scroll the thumb wheel down. The direction, whistle, and bell buttons will control your conventional trains. DCS locomotives on the track will ignore all commands unless they are addressed from the remote.
