Hello. I'm in the process of wiring up the two NPN NC proximity sensors to the c10 BOB. I've read since they are NC that they should be wired in series. Is that correct? I've also read that I require a resistor to drop the voltage from the +12v to around +6v for the c10. I've read I should use a 10k ohm resistor but I guess that would change after its wired in series? A diagram would be most helpful.

All help is appreciated. Thanks.
