Connecting TMCC to Multiple DCS TIUs??

Pretty sure you just need to connect it to one TIU and the job is done.

Hello GunRunnerJohn! Good to hear from you. I was expecting something complicated....no wonder I couldn't figure it out !

I see you're a MTH ASC Certified Technician. I have a quick question for you. I unboxed a RailKing Santa Fe 4-8-4 and fired it up. It ran just fine except for the sound....could barely hear it.

After removing the tender top, I saw the speaker and it looked like it was covered with some kind of "fuzz". But it wasn't fuzz......it was particles from the speaker's magnet. It looked like it was covered with iron filings! Have you ever seen this before?? I'm guessing these particles are keeping the speaker's voice coil from moving? What a mess!

Well, this is an older model, right?  First off, do NOT run it any more until you get the speaker replaced!  This was something that was happening to a lot of the older 5V models with a 16 ohm speaker, the coating coming off the magnet.  In an extreme case, these can actually short to the frame and kill the audio amp, not a good thing.

I have 16 ohm replacement speakers if you need one.

Yep...this is an older model. The markings on the speaker are "STATR or STAER or STAR NR-05009-01 16 ohm 5W 354E".

I emailed MTH on 9/2 and heard from Kirstin on 9/6 that she passed my email on to the Parts Dept. I was thinking MTH might cover it as a defective product...but now I kinda doubt it (not sure what happened to the font here). 

Anyway, I have a request in to MTH so I'll wait to see what they say. But I do appreciate the help .......

And yes...I'll stop running the engine.

Thanks for the help with the TMCC/DCS connection......

Yep, that's the one that frequently dies.  It's an old 5V unit, and a host of them developed the same issue.  I used to have about a dozen of the defective speakers stuck to my workbench legs, then I decided to clean up and toss all of them.

It doesn't really matter  which tiu you  select to add the   command base   ,however when going to add a  TMCC engine you must  select  that same  tiu ( the one the base is connected to)

GunRunnerJohn.....I'll email you to find out the cost of the speaker with shipping and how you handle payment. I'm guessing your replacement speakers don't suffer from a bad coating.....

Gregg.....Thanks for the heads up about adding TMCC engines to the TIU the Command Base is attached to. I'm hoping TMCC engines can run across TIUs using Super TIU like MTH engines do.....

 I'm hoping TMCC engines can run across TIUs using Super TIU like MTH engines do.....

They certainly can... we have 4 tiu in super.   Part of the success is having a good common...

Once the engine is loaded into a TIU that your remote knows about, it'll run just fine.  The TMCC signal is everywhere on the rails, kinda' like a fart in a space suit.

LOL.......just remember....."In space no one can hear you scream" (Alien)....
