Was getting impatient as far as the new DCS from MTH and saw a new unused remote (50-1038) so bought it. My old remote is the same except the new one on the back it says “50-1038” below the FCC info. My TIU is old so that to upgrade software you need some sort of special cable so I am running version 4.10. My current remote has a balky thumbwheel so part of the plan is to get the new remote working and use it while old one is out somewhere for repairs and then later use one remote for trains (three) on upper track and the other for the lower track with as many as five trains. Finally, do not have a 12 year old handy to help with the technical aspects of this so asking here.
First goal is to do whatever I wind up doing without causing me not to be able to run trains with the TIU and remote(s) I have. I have to do this DIY as I am not aware of anybody local to me who could assist.
One issue I thought of after I bought the new remote is whether the software is stored on the TIU or the remote as I doubt stuff will work if my software version is not the same on the TIU and both remotes. So hopefully the software is on the TIU so that I can add the second remote without upgrading the software version.
If that is the case, how do I add the second remote?
When I add it will all my locos be in it or will I need to add them separately?
What other issues am I looking at that I have not thought of?
Many thanks.
