QSI Sound decoders in Atlas engines
#1
My Atlas engines with QSI sound decoders arrived with a small booklet explaining how to program. There are long section about sound programming for DC only as well as DCC operation. Both booklets I have do not mention how to program the basics of DCC motor control and I assumed there are no CVs t be programmed for motor control. The engines had an awful jump start and a lightning top speed. I considered QSI decoders as barely useable and replaced them with other (none) sound DCC decoders.

This an example of Atlas documentation for those decoders

I stumbled last night over this very similar document
http://www.atlasrr.com/DCC/Revised%20%20...Manual.pdf

All of a sudden is there an appendix 2 (page 50) listing all the usual CV I am used to. Indeed the QSI decoders has most (my old version has no CV6) needed to setup a smooth and slow running switcher (MP15DC in my case). e.g. CV 2-5 set to 1,5,5,80 results makes an outstanding switcher on a small ISL Big Grin

I post this just in case you are irritated like me by the little printed booklets shipped with the model not mentioning any CVs to control the motor.
