DT400 can be set up to handle stop commands globally or locally.
The default is local control.
With local stop, when the EMRG STOP Key is pressed once the loco on the active throttle will stop and when the EMRG STOP Key is pressed a second time, the loco on the other throttle knob will stop.
To resume operation, use the throttle knobs to increase speed of the locos from 0.
With global stop enabled, pressing the EMRG STOP Key will stop all locos on the layout and you will see the DT400’s track power indicator blinking on and off.
To resume operations, press the PWR Key followed by the Y+ Key to return locos to their speed prior to the EMRG STOP.
