stan2004 posted:Stop the presses! I gave you bad information on the Z-controller. I examined mine and it appears "Black" is NOT common between input and output. Instead it the "Red" that is connected internally. OTOH for the DCS-RC, the "Black" is common between input and output. I'll have to revise my diagram. Maybe it can still be done with "just" a DPDT configuration but as you have intuited, it may require a more complex (e.g., 3P) switch type.
If you have a meter, with nothing connected to the Z-controller, could you measure the Ohms between the input center-pin and the output "Red" banana...and separately the Ohms between the input "sleeve" and the output "Black" banana? You can plug in the barrel-connector with pigtails if it makes it easier to attach the meter probes.
Boy do I know the feeling.
Up is down and down is up.
I will check that out and, if I find as you suggested, I will try it again with regard to the reversal.
Thanks for checking into your controller.
That is going above an beyond, and I sincerely appreciate the effort.
