QUOTE (rickb @ 7 Nov 2006, 18:35) <{POST_SNAPBACK}>Sorry for not understanding your reply. I can't think of a smoother smooth DC than you get with a rheostat - provided it's feeding from a smoothed power supply, of course.
Does anyone know what range of inputs is expected for the jump terminals? e.g. 0V to +/-12V, or 0mA to +/-200mA perhaps.
R.
A "rheostat controller" to me implies an ancient piece of kit that only produces any kind of control when connected to a load such as a locomotive.
I would try turning the control up to maximum and then wiring a 10K potentiometer across it with the controller outputs across the track of the pot and the pot slider connected to the jump port. You'll also nee a common connection from one side of the controller.
