Re: Photoeye's not working-Difference between RoboRIO and Digital Side Card?

Chris,
I would suggest the same thing, although I think I would start with 10k to limit current. However, I am still trying to analyze why a meter, testing continuity, between two common points should make this work. The lights on the sensor indicate that switching is taking place. I would expect that the output of the Banner sensor is a photo transistor that includes a series resistor for over current protection. However, simply connecting a meter seems to indicate that the power common wiring is not as low impedance as one would expect. I would suggest someone with a scope actually check the operation of the sensor and report your findings.
