Wi Fi unit Powering TIU | O Gauge Railroading On Line Forum

I have a layout utilizing 3 MTH Tiu(s) with Lionel 180w Power Bricks. Each TIU has 4 Bricks.

The Tiu's have separate power supplies and are current Versions with USB.

Everything in the system is current revision.

Added a Wifi unit recently for testing purposes and realized that by using the USB cable out of the Wifi unit

into the TIU USB input Powered the TIU. No issues so far, but the wall wart for the WiFi unit does not look particularly robust.

The question is: is there any real downside to having the WiFi unit powering The TIU thru the USB cable?

Thanks,

Buzz,

is there any real downside to having the WiFi unit powering The TIU thru the USB cable?

Yes, there is. The USB connection doesn't power the DCS signal generators.

If you attempt to operate an engine on Fixed #1 or either of the Variable channels without power to either Fixed #1 or the Aux. Power port, you won't be able to do so.

DCS Book Cover

This and a whole lot more is all in “The DCS Companion 3rd Edition!"

This book is available from many fine OGR advertisers and forum sponsors, or as an eBook or a printed book at OGR’s web store!

Thanks Barry:

I believe there are two choices.

Maybe others?

Go back to a USB to Serial Cable and power the TIU from a dedicated power supply.

That should work.

Or

Use the USB Cable as supplied (WiFi to TIU / USB) but, also use a dedicated power supply for The TIU.

Your help is greatly appreciated.

That would be my preference.
