MTH AIU/ Ross Switch/ DZ2500 Wiring Diagram

Here is the diagram from the instructions.  Green and yellow are not used.

So it should look like this.

Thank-you CAPPilot.

Relooking this, I believe the black wire out of the switch machine needs to be connected to ground.  I use the DZ-2500 in the one-wire TMCC mode, not the 2-wire DCS.  For me, the DZ-2500 needs to be powered all the time, but I am not sure about DCS.  However, the Z-Stuff diagram shows the black wire connected.  

So the black common wire out of the switch machine needs to also run to the AIU "In" port.   That does look correct from the diagram.   Thank- you for posting.

To help anyone in the future who is having trouble wiring a Ross switch with a DZ2500 using an MTH AIU, this is what I found.  When I follow the wiring diagram from Z-stuff for the DZ2500 (Figure 5) with the blue wire going to AIU 1 and the white wire going to AIU 2, only the turnout button on the MTH controller (app) will move the switch from straight to turnout and also turnout to straight.  The straight button does not work when wired this way.

After researching other people's troubles, I found that if you wire the DZ2500's yellow wire to the AIU 1 and the green wire to AIU 2, everything works as it should.  If anyone has other suggestions or comments, please leave them.  I do not claim to be an expert, I am just trying to get everything to work properly.

The black or common goes to the common on the power supply and to the AIU "In".  The red wire simply goes to the red of the power supply.
