Legacy voltage compatibility with DCS

Transformer voltage does not go through your Legacy.  I think others can confirm.  Enjoy the benefit of both.  You should be good to go.

Legacy engines should be limited to 19 V.  What transformer(s) are you using to power the tracks the Legacy engine will be on.  Whatever the transformer is putting out just passes through the fixed channels on the TIU to the track.  A Z-4000 can put out 22 V.  Just set it at 18 V and you will be okay.

I’m just using the Lionel 180 watt power bricks. After posting my initial question, I ran an MTH locomotive around my layout and checked the track voltage through the remote control at different points along the lAtYourGate. It was always below 18 volts. 

I guess that the DCS remote is programmed to display up to 22 volts due to the fact that the z-4000 is capable of producing 22 volts, even if the track isn’t seeing that much voltage from other transformers.

If you use the DCS WiFi app you can read track voltage on your device.  My handles are set at 17 VAC, but track voltage read is 15.6.  I don't think you are going to have any problems here.  Enjoy the benefits of both.  Having both is better than being limited to one.  Both are good.

You need to use an actual voltmeter to get an accurate reading. The remote reading is on a proportional scale and may or not be the actual voltage.

If you power the TIU with the PH180 brick, you'll be fine.  The TIU doesn't put out more voltage than it takes in.
