Basic ProgrammingStep 5: Function MappingFunction Mapping ExplainedFunction mapping allows the DSD to be reconfigured so that sound effectsand function outputs can respond to a different function key input. This isespecially useful for users who have throttles with less than thirteen functionkeys as now they can pick and choose what effects they can control insteadof being restricted to an arbitrary assignment.There are 14 function mapping CVs - twelve CVs, 35-46 are used to assignoutput control to function keys 1 through 12 respectively.The other two CVs, 33 and 34 are both for the F0 function. CV 33 controlswhich outputs are on when F0 is on and the locomotive is moving forward.CV 34 controls which outputs are on when F0 is on and the locomotive ismoving in reverse. If the same output is selected in both CV 33 and CV 34,that function will turn on when the F0 function is on regardless of locomotivedirection.Not all keys can control all outputs or effects. The table below shows whichfunctions can be mapped to which outputs. Note that a function key can beset up to control more than one output.Table F.
