Robert,
I note that you have been recommending the R-S power supply on the forum for many years, and I do not recall that, until recently, you have stated that it was not suitable for AIU-equipped TIUs.
That's correct. However, even I learn something new, occasionally.
Regardless, the RS supply is good for only a limited set of DCS implementations, and should not be construed as any kind of a "silver bullet" as regards providing TIU power.
The other misconception floating around is that the USB port on the Rev. L TIU is a good way to power the TIU. It is, but only for providing power for TIU and DCS Remote upgrades.
I learned through experience that there's a huge difference between powering the TIU via the Aux. Power port and the USB port.
While the Aux. Power port powers all of the DCS signal generators, the USB port powers none of them. Therefore, USB power does not allow DCS sound file transfers, or DCS engine operation at all, except using Fixed #1, with track power coming in through the Fixed Channel #1 input.
