Speed tables

[rrinker]

No, there are 28 CVs to set for a speed table, not 128. With some decoders, the 28 step speed tables only work if you command the loco with 28 speed steps - this is handled by your command station, not the programming in the decoder. Other decoders, even if you send them 128 speed steps, will interpolate values from the 28 individual entries and give you approximately the same curve even though you are sending many more actual steps. There are ALSO 3 step speed tables using CV2, 5, and 6, but not all decoders have that. Tsunamis for one do not have CV5 and 6, and I don't think the MRC onces have the mid speed CV, CV6 - their 'menued' programming system skips setting that so you have to do the option to program individual CV in order to set CV6 on decoders that DO have it - all current DIgitrax, TCS, and NCE decoders support all 3 and you can usually get quite effective response just from those 3. And you do not have to convern yourself with speed steps, CV2,5, and 6 work regardless.
