Using Tiu variable channel and Z-4000

TIU fixed channels cannot be changed to variable.  Variables can be set to fixed, but only via the remote.  Without a remote, your DCS locos will still get a watchdog signal from the TIU and you will be unable to control them without a remote (or a wifi app).

With no remote, all you can do is used fixed channels and run conventional.

Hi Rjr,

You may have misread my question but not sure, I am not trying to change the fixed channel to Variable via the remote, I took the TIU and re-routed my input/output fixed channel wires to the variable and the power is from the Z-4000. I was asking in this case, do i just now hook up an external power supply?  The reason for doing this is that my remote is in the repair shop...Thanks

So how do you plan to control the variables?  Unless you set them to fixed before the remote went to the shop, you can't control them.  Go back to the fixed terminals, and use external power supply.

Ok so even thought I am using a Z-4000, I still have to use another power supply for fixed 1??

Sorry somewhat confused here.

I believe I have some confusion cleared up, from what I understand, you cannot run through the TIU unless

you are using the DCS remote, to run conventionally, I have to wire my Z4000 outputs to the track, is this

correct?

In brief, yes.  Without a remote (or WIU), you can't change any TIU settings, as would have to be done.  Without a remote, there's nothing to be gained by having a TIU in the mix.

Ok will do, it seems I may need a new thumb wheel and the shop says that MTH has them on back order, so the money that i spend for  a new remote I may as well go with the WIFI system I presume.

I make no comment, pro or con, on the wifi.  I have 2 WIUs & 4 remotes; you either love WIUs or hate them. 

If your remote is in a local shop, you might want to retrieve it and check with some of the techs who frequent this forum, such as GGG, who keep them in stock.  I would not dump a remote that only needs a cheap thumbwheel, a 10-minute cheap repair job.

Hi - I was not going to dump the remote by any means, Ok I thank you for your input.

RJR,

   You and I have been running DCS sense it came on to the market, and this is one thread that is more than just a little hard to follow.

Trackhead,

RJR gave you good advise, retrieve your DCS HHRC and have GGG here on the OGR Forum fix the thumb wheel for you, purchase Barry's DCS O Gauge Companion book and the OGR Video Guide to DCS.  After doing some reading and maybe watching the Video we will help you in any way we can.  

Please pass the Russell's down this way.   Keep the ice!
