Will a Legacy handset work a TMCC base?

Nope.  You need a Cab1 for that.  As I understand the reason for the "Y" cable and connecting the TMCC command base to the Legacy base is to allow the Cab1's to continue to work.  Legacy bases and TMCC bases communicate on a different frequency to their respective handhelds.

Thanks Mitch, darn it.

Hi Dave,

          If you have DCS on your club layout you could use DCS controllers to run TMCC.

A cable connects DCS to the TMCC command base so they can "talk" to each other.

Actually, the PowerMaster Bridge is ONLY for using PowerMasters with Legacy.  The TPC receives it's signal using the serial cable from the base, not from the handheld.  In addition, if you have a PowerMaster Bridge in the configuration, you can not use any CAB1 units as well, they will conflict.

Hi Nick,

yes we have DCS. The trouble is, when using a DCS controller, for some reason, the loco starting speed is way too high. We have scoured Barry's book and just can't find a fix. Barry advised me the problem was not in the DCS system. But, every loco we try fitted with TMCC behaves like this. So, I will just use a Cab1.

If anybody has an answer, please tell me.

Dave I have both TMCC and DCS I will run a couple of Lionel engines and get back to you.  I don't recall noticing that they start out running at high speed though.

Bill,

I've never heard anyone else complain either. I'm sure we are missing something, but we just can't figure out what it is.

Dave, 

        Could this be something to do with the stall setting for TMCC Locos? I seam to remember someone mentioning that the DCS remote has no way of setting the stall or doing a loco reset for TMCC.

You would have to do this with a Cab 1.

I can't say I have tried running TMCC via DCS as I have Legacy and would not be able to use the extra Legacy features from the DCS remote. I did pick up the TMCC/DCS cable when I picked up my DCS set in the States just in case though. 

Regards

Nick

Nick, thank you for the clue. I will look at this. It indeed sounds feasible, given that Barry said it was not something in DCS doing this, and I would never question his knowledge on the DCS subject.

Dave, a funny thing happened to me on the way to .... .

First I tried to run my Alco Pa's, the diesel sound only played for a few seconds and then went off.*  Hmmm, needs a battery? No, the same thing happened with a fresh battery.  Out side of that the engine ran fine, no high speed take offs.

Next I put my MR 2338 on and I had no issue with the diesel sounds and this engine ran flawlessly.  I did notice that with the ZW transformer set at 18, I had to scroll the speed up slowly.

*Anyone have an idea as to what would cause the diesel sounds to only play for a few seconds?  BTW it would do this whenever I pressed the startup key.

Was your layout fully functional with the TMCC base before you switched over to the new Legacy base?  Did you change any wiring?

How many devices do you have wired to the serial output of the Legacy Base - 3 TPC's + anything else??  There is a limit on how many devices the Legacy Base can drive.

Do you have the power bridge from lionel connected in your system?

In response to Dale's and Balto's questions.  The TMCC was fully functional BEFORE I hooked up the new Legacy. With no problems at all.  (It's been running for the last 6-8 months.)  I figured it (Legacy) would be pretty much the same (no problem) hook up as hooking up the TMCC Base with the SAME wiring.  The only things I had hooked up to it were the 3 TPC 300's.  They were all hooked up in "daisy" as stated in a video I received from Lionel. (Before I even hooked up the TMCC I sent Lionel a message and this is how they told me to hook up the TMCC.)  (Lionel did advise me not to hook any more than the 3 TPC's up to the new Legacy System.)   I sent Lionel a message on Wednesday informing them of my problem.  I read about the "Powermaster Bridge" in the manual.  I thought this was my problem also. (I even was about to purchase one.)   I got a reply back from Lionel Thursday morning telling me that the "Powermaster Bridge" wasn't needed.  They also sent 4 video clips of how to hook up the Legacy System with TPC's.  I had my system wired exactly as they had it on the video.  After playing around with it pretty much the whole day Thursday; this is when I discovered the burned out TPC 300 in Track #1 and the blown in-line fuse in Track #2.  Thanks Guys  TT

Dave,

The trouble is, when using a DCS controller, for some reason, the loco starting speed is way too high

There are two things that you can try.

The first is to use soft key SPD to set the remote for 128 speed steps instead of 32.

The second is to use soft key REL to change the remote to work in relative speeds steps instead of absolute speed steps.

This and a whole lot more is all in "The DCS O Gauge Companion 2nd Edition", now available for purchase as an eBook or a printed book from MTH's web store site! Click on the link below to go to MTH's web page for the book!

The fact that you have a COMM led is encouraging.  That probably means that the internal power supply isn't dead.  Can you get the COMM led to flash when you send a command to the TPC?
