Editing TMCC address to a new address

If you use your Legacy to address and run the engine and it’s #21. To add it to the DCS remote. There is no need to access the program, run switch. The layout doesn’t even need to be powered up. Only the DCS remote needs to be on. Just follow the manuals instructions and be sure to assign it to the TIU that the Legacy base is plugged into if you are running in Super mode.

@Missabe  I've posted on this issue along with others on this issue. The only thing DCS will do is assign a TMCC ID which you provide to the DCS Remote/app - it then will assign a DCS ID number to the controller. It cannot change the engine ID on the engine.  If the DCS number does not match the engine ID, nothing happens. If you do not know the TMCC engine ID (default is 1 for a diesel), you must change the TMCC engine ID using a TMCC remote using the program switch located on the engine to the desired ID. Switch back to run and it should then be recognized.

I assume you have the TIU cabled to the TMCC base unit which is properly connected to the track. Took me hours of frustration to figure this out and once I did - it really is pretty simple. On-line instructions are way too confusing and inaccurate in my opinion. BTW the engine TMCC ID is completely different than the DCS ID - that's where I was getting confused. 

The other thing that catches me all the time is running conventional. The TMCC engine will not respond to conventional signals/power unless the TMCC base is unplugged. 

Scouting Dad,  The DCS will apply the TMCC locomotive to a vacant address on the DCS remotes (inactive engine list).  Let's say #5,  I then click on it and move to the (active engine list) #5.  The TMCC locomotive will then operate with the DCS remote.  Because the TMCC ID #21 is assigned to the legacy remote.  It would be easier to remember TMCC #21 and the DCS # were the same ID #.

(DCS)  When I activate ID address #5, then go to menus edit address and change #5 to the vacant new address #21.  The remote reads at "#21 is new address is #21 and done".  When I go back to the active engine list the TMCC #21 is still listed at DCS #5.  There is no knew address #21.  I moved engine addresses many times to new addresses and never had a problem.  Most   of my engines are DCS, only a few Lionel or AtlasO Legacy engines.  I guess I will have-to live with DCS assigned address.

I very much appreciate your time and help,

Gerry

I thought when you added engines to the DCS remote they were added into the next available slot. Just wondering if you could enter non existent  TMCC engines into the remote till #21 becomes the next open slot. Then simply delete the phantom engines. Would be time consuming but you can add TMCC engines while watching TV.

Apologies - I can sometimes not be very clear with written instructions. I think in flow charts so maybe this will be helpful. The DCS TIU only sends the TMCC Engine ID and command to the TMCC base, which in turn transmits to the engine(s).

I suspect the DCS handheld or App, is what stores the DCS engine number and the TMCC engine ID.  When it sends a command to the TIU, the TIU decodes the signal and sends the instructions to the TMCC base. (I cannot find the details on how this operates, not in Barry's book as far as I can tell.)

In the App, when setting up a new engine, it asks you for the TMCC engine ID, it will then assign the next DCS engine number and enter any name you wish to call the engine. DCS handhelds may be different. Unlike DCS it does not look for the engine on the track (no return signal), you just need to put the TMCC engine in the active list.

NOTE: 1) DCS cannot change the TMCC engine ID.  2) Barry shows a way to get the DCS engine number to match the TMCC engine ID if desired.  3) @dave c. you are correct about the work around - basically the method Barry suggests. 4) just a guess - it should be possible to have a DCS engine with the same engine number as a TMCC engine ID ---  BECAUSE --- DCS will assign that TMCC engine a different DCS engine number. 5) @Missabe  from what you describe - you can use the method Dave C describes to move the DCS number to 21.

Hope this is clearer. 

Dave, I tried that using phantoms in all open addresses up to #21.  

There must be a gremlin with TMCC ID 21 and DSC address #21.
