Speed Step For Starting Voltage Adjustment
Posted by maxman on Monday, December 6, 2010 10:49 AM

Okay, just a minor point.  When adjusting the starting voltage to get the engine to move at speed step 1, is that speed step 1 on the zero to 28 range, or speed step 1 on the zero to 128 range?  And yes, I know that all the 128 speed step range does is break down each of the 28 speed steps into smaller pieces.

Thanks.

Depends on what you have your throttle set to.  If you have it set to 128 speed steps then you are programming for speed step 1/128.  This is the way it should be done for decoders that support it.

 If using 128SS mode, you might consider making the starting point at step 2, so there's that one click dead space in case someone twists a knob without looking to see if they really are on step 0 when coming to a stop.  At the same time that might NOT be good because while a loco might not start from a stop on speed step 1, it might be able to continue moving if slowing down from a faster speed. Which might not be totally bad, either. Confusing? Yes, I am managing to confuse myself. There are pros and cons both ways, so you have to just think about it and decide how you want to proceed.
