[quote user="KingConrail76"][quote user="Falls Valley RR"] <p>Also DCC has different function keys. Maybe F2 for a bell. Some manufactors will put in thier OWN system to control the engine.</p><p>Even worse, the CV (Configuration Variables) aka switches inside the Decoder's brain are different from one maker to another. If I was to say configure CV # something to make a bell choice something for a QSI engine... it will NOT be the same value or something for another MANUFACTER of a different engine... like MRC.</p><p>Until DCC is truly Common across ALL of the software and the controls UP TO the limits of the hardware used... we will never enjoy peace from the noise of the tower of Babel.</p><p>[/quote]</p><p>Really??? I thought CV#'s were standardized under NMRA Recommended Practices? I mean, I know some manufaturers do not use all CV's that are available, but I thought that CV# such-and-such was always that particular variable. Like say CV#1 is always the Loco's address, and CV#3 is always speed increase momentum, and CV#19 is always Consist Address...No??</p><p>[/quote]</p><p>Uh, sort of.</p><p>I think I bit off more than I can chew here.</p><p>Let me try to explain.</p><p>My MRC 4-4-0 had CV numbers on their own chart. It was a rather small chart... maybe 20 CV's each with options. Yes there was the start voltage mid etc.</p><p>Now park the QSI engine and look at that manual. Downloaded as a PDF file off the internet for the engine presents ALL of the CV's PLUS Bit mapping etc etc etc etc etc.</p><p>Kinda like being told that this button or number is for the bell on one engine and totally something else with another manufacter's engine because they felt like writing these values thier own way and not bothering to make sure that a value is the same across the entire hobby range of decoders.</p><p>Maybe SOME CV's are the same because they have to be.. but it will be very nice to see ALL CV's the same across the board.</p><p>I'll shut up now before I confirm my total lack of understanding.</p>
