two TIU's #1 on same layout?

Ed,

I was wondering if having 2 TIU's with the number 1 on my layout would work to help get better signal strength.

That's a recipe for absolute disaster.

 

TIUs should always have different numbers if a remote can see more than one TIU.

Thanks for the reply Barry. I was afraid you might say that. I'll have to delve deeper into your book to try and understand what specific problems that might lead to. Would it be OK to have TIU #1 run the lower level and make the upper level TIU #2 and not run in Supermode? If all engines were added using TIU#1, can I run them on the upper level with TIU # 2 by using the Read button?

 

Ed

Yes, you can do as you posted without any issues, however, doing the READ is, in my opinion, a somewhat crude process, If you just use Super mode, it's all seamless. That's what Super mode is for.

Thanks again Barry. I guess I'm concerned about some possible problems I read about with fast speed scrolling in Supermode. I tend to do a lot of fast scrolling.

 

Ed

Ed, The issue (there's only one) with fast scrolling has been blown way out if proportion. Further, the workaround solution, that I use every day, is simply to use Quickset Speed to tell your engines to accelerate or decelerate to a certain speed. If you plan to use multiple TIUs and operate the same DCS engines on all of them, Super TIU mode is what you should definitely be using.

Many thanks again Barry for being so generous with your help. I hope you and your family and everyone else on the Forum have the best Thanksgiving ever.

Hi again Barry,

 

Was reviewing some info on TIU and engine associations,etc. Then was thinking about what problems 2 TIU #1s would cause on the same layout. If you get a chance after eating turkey, could you please let me/us know what some of the main problems would be with having the 2 TIUs with the same number on the layout.

Ed

Ed, Mostly error messages and loss of control.

Barry and Greg,

 

Error messages and loss of control don't seem too good to me. Ive got 3 remotes but don't want to be tethered. I'm going to read up on Quickset speed control with Supermode but I think the last time I tried it I didn't like it because the train seemed to speed out of control. Seems like I can get a workable solution to trying to improve the signal strength and running the two levels. Thanks again for the guidance.

 

Ed

Gregg, The bug you reference as regards lashup members is not a Super TIU bug, rather it is also present when operating in normal TIU mode as well. Further, it only presents itself in certain specific situations and it's completely preventable.

Barry,

Is the speed scrolling bug in Supermode present all the time with fast scrolling or only occassionally on some layouts?

 

Ed

Ed, AFAIK, all the time in Super mode.

Barry I didn't mention anything about lash-ups on this thread. I'm referring to any engine that ends up in the inactive list in a tiu zone other than the one it was added to. The engine will not come out of the inactive list. With 4 tiu in super this can be a  problem . Thankfully we know about this problem and never use the "read" because of engines left on toggled off siding through out the layout.

 

Had fun the other day doing some house cleaning with the remotes. , We have 7 remotes and an engine with ID 21. somehow ID 21 vanished from one of the remote and we wanted the engine in all the remotes. Took a while to discover that everytime we used the remote with ID 21 missing it would change the iD number to the lowest available ID making ID 21 invalid in all the other remotes..
