@AcelaNYP posted:In short you would not need to change your wiring diagram when using the Z4000; simply disconnect TIU barrel jack adapter and connect the wires from the TIU to either the Track 1 or Track 2 ports on the Z4000.
One possible tweak is to eliminate the Variable 1 Input - Fixed 1 Input jumper wires and moving the Variable 1 Output wires to the Fixed 1 Output. Doing so will eliminate the ability to set track voltage through the DCS remote, but the voltage can still be manually set with the corresponding the Z4000 throttle.

Not sure if I understand your second paragraph.
If I eliminate the Variable Voltage connections how will I control the track voltage for my conventional steam locos?
If I use the Fixed Voltage 1 output won't that put ~18 volts to the track all the time? If so, would the Z-4000 throttle override that fixed voltage? Certainly confused.
