Re: Wiring previous-year banner sensors
We're using the QS18 this year.
Brown = +12V on the power distribution through a 20A
Blue = GND on the power distribution
Black = Do not connect
White = Run this wire, and ONLY this wire to the digital sidecar, any Digital INPUT, to the SIGNAL pin - where the white wire on a PWM cable would go.
These are sinking outputs, and the DSC has pull-up resistors in them. It's a common ground from the digital input to the power distribution board, and so this works without too much of a problem.
Good luck!
