DCS Remote Commander/Lionchief Plus and Smoke.

Some things of which you should be aware:

• The DCS Remote Commander cannot turn smoke on or off for PS2 or PS3 engines. For that, you need the full DCS Remote and TIU set; or DCS TIU, WIU and DCS App; or DCS Commander (different product from the DCS Remote Commander).
• The DCS Remote Commander cannot control your Lionchief Plus engines at all. It can only control PS2/PS3 engines that have been reset to Factory settings.

Further, although newer PS3 engines can be Factory Reset using the DCS Remote Commander, older PS3 engines and all PS2 engines cannot. They require either the full DCS Remote and TIU set; or DCS TIU, WIU and DCS App; or DCS Commander.

• The full DCS Remote plus TIU can only control your Lionchief Plus engines as conventional engines, and cannot control their smoke on/off. However, you can can continue to use your Lionchif remotes with those engines, even on the same tracks that the DCS TIU is using.

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!

Like Barry says, you have the same issue with PS/3 if you use the cheap DCS Remote Commander.  The bonus with MTH locomotives is you can upgrade to the full DCS system as they're full-featured command locomotives.

Thanks for the info on DCS remote not controlling smoke units on ps2 or PS3. 

That about answers the question on the MTH remote.
