Horn does'nt work TMCC Remote

If you turn the sound off in command mode with the remote does it still function normally in conventional mode?

Can't recall if we've ever tried (aka "done in error by accident") it.

When's the last time you changed the cab-1's  batteries.? I'd start there.

The smoke defaults on in conventional mode, so you may have it turned off in command mode.

Look in your TMCC manual how to turn up the volume, the person who did the repair on the smoke may have turned the sound mode down. You may also want to try a reprogram of the engine.

In conventional, the volume is controlled using the volume pot, the TMCC setting doesn't apply.

I went to reset my TMCC 4-4-2, hopefully to restore the horn key on the remote.  Now the engine doesn't reset.  But the horn sounds when ever any key is pushed, except the Horn key.  Engine doesn't respond in command.

I tried to install this engine to run in DCS.  It allows me to register to the TMCC roster.  It keeps coming up no engine on track?  I tried everything according to the Cab 1L and Base L manuals and DCS Companion manual and manual for the DCS remote.

The symptoms suggest the RUN/PGM switch is in PGM mode.

When resetting the R2LC step 1, switch from Run to PGM.  I followed the steps to Step 5, press ENG and ID# and AUX1 and the #4.  When #4 is pressed, that's when horn will sound on every key when pressed except the W/L key.

Are you trying to set this up using the DCS system?  Do you have a TMCC remote to configure it?

Yes.  I have DCS Remotes, TIU's and AIU's.  TMCC Base-1L and a Cab-1L remote.

Are you saying you can't get this working with the CAB1L remote?  Do other TMCC engines work?

yes.  I have 1 other Lionel  and Atlas O engine.  I will try one.

The other Locomotive operates  fine with the Cab-1L remote .

Sounds like the engine in question may have a problem.

Horn problem solved.  When GRJ suggested check another engine to see if the 0-8-0 has similar problems as the 4-4-2.  I also had the 0-8-0 manual.  Finding none.  I decided start from scratch.  GRJ also mentioned a Run/PRG problem.  Evidently, the two manuals are very similar.   The 0-8-0 manual tell how to set the Quilling  for the W/H. Following the instructions restored the W/H.

I must be missing something?  Neither engine will run in DCS?

What do you mean "run in DCS"?  If they're Lionel TMCC, they MUST have a TMCC/Legacy base controlling them to run in command mode.

If the TMCC base isn't properly cabled to the MTH TIU, that would explain not being able to run them from the DCS remote.

It's cabled from the Base-1L output to the TIU input.  Cable end labeled Legacy Base is connect to Base-1L the other end is to TIU labeled .

I don't have a clue why that doesn't work if it works using the CAB1L, the same engine, and the same TMCC ID.  I just add a TMCC engine and pick the same TMCC ID as it has already been configured for.  That's never failed to work for me.

The ground wire or Track U is attached outside rail FasTrack with female spade connections.  The TIU is attached to 2  Terminal Blocks one 24 ports the other 12 ports.

Unless I am misunderstanding he TMCC ID

Since you can control them from the CAB1L, I suspect you understand the TMCC ID concept.   When you add a TMCC engine, you scroll to the same number as you used to control the engine using the CAB1L.  That's really all it should take.  Since TMCC works, all the stuff about track blocks and TIU ports is moot.  The only connection that is important is the cable between the TIU and the TMCC command base.

When you have a TMCC engine selected on the DCS remote, do you see the light flash on the TMCC command base when you try to control it from the DCS remote?  If not, that tells me there's a problem with the cable connection between the two, or at least one of them has a problem with the serial port.

I will try to Edit the engine address.  My error could be, not having the engine PRG/Run switch in PRG.

It flashes Red.  When I select TMCC engine.   The ID is just 1,2,etc  correct.

If you have the engine running on the CAB1L at engine 10, for instance, you do NOT have to tinker with the PGM/RUN switch.  Leave it at RUN and just pick 10 when you add the TMCC engine on the DCS remote.  That's really all there is to it.

GRJ,

Thanks for setting me straight on the ID #'s.  TMCC  engines  working in DCS as you instructed.  I copied your comments and added them to the DCS Companion, TMCC chapter.  It's easy for me to forget, so for future reference.

Great, I'm glad you sorted it out.  Sounds like you were just making a simple task complex.
