You can power the TIU through Fixed 1 with DC. I program all my boards using a DCS Commander and can access the board/loco using my DCS remote.
You can also power the TIU with a Z500 brick via the Aux input. A switch in the TIU disengages the power fed into Fixed 1 to power the TIU when the plug is inserted.
