JohnActon posted:Lou1985 posted:JohnActon posted:Lou, my response is based on a discussion that started on 2-2-17 "Lionel Railsonds history" it is worth a search and read. This is a quote from that discussion by GGG in response to a post by Mike Reagan.
"Wasn't part of this that RS up through and including RS 2.0 were conventional only? RS2.5 was the first TMCC based RS and that was in the early NYC/SP GP-9?
Also RS 3.0 board does require the early LARGE power Supply board. After RS 3.0, the powerboard became universal and smaller. Even works with modular Legacy.I have moved RS 2.0 chips into RS 2.5 platforms and they work in TMCC mode. But the 2.0Hardware is not command capable. G"
The RS2 boards were the first to use removable programmable PIC and ROM chips. The chips in the RS2 board could be transplanted into the RS2.5 board and give full TMCC capability. However the RS2 boards do not talk to TMCC. j
I noted above that Railsounds 2.5 and above boards can be used with TMCC. Railsounds 2 is a conventional only system stock. Came out in 1994. In 1995 TMCC came out and Railsounds 2.5 was introduced at the same time to communicate with the LCRU/LCRX, even though the catalog still called it Railsounds 2.
We would be able to let the OP know if his Railsounds 2 board would work with the DC Commander if we had a part number for the locomotive the board came out of.
As an aside I have a Railsounds 3 GP9 board connected to an AC Commander in a GP9. It's got hours of runtime on it and works fine.
Lou you might want to go back and read your original post. The original post by RRADDICT was about RS2 it made no reference to RS2.5 and my response was directly about RS2 and you write, "Nope. Any TMCC capable Railsounds2 board can be connected to the DC Commander no problem." I guess I get hung up on the word "Nope" as though my explanation about his RS2 problem was incorrect. j
I think we've both missed each others point. Railsounds 2 is digital. There is both a 2 and 2.5 version. Railsounds 2 came out in 1994 and some of the early boards from 1994 do not have serial input. By 1995 Railsounds 2 boards were TMCC serial capable, as TMCC was introduced. So in a nutshell if the Railsounds 2 board the OP wants to use is from 1994 it wouldn't be TMCC capable because it's not digital, but because the board isn't programed to accept serial data. So long of the short is all Railsounds 2 boards are digital but not all of them (the early 1994 ones) have TMCC capability.
