Hey
I am making a simple revcounter for a experiment setup. It consist of a photocensor (Omron EE-SX461 P11) and the NI 9401 in port 4 in a NI cDAQ 9174.
I am not sure how to wire the photosensor to the 9401. So far I have done it like the illustration (ill.png), but nothing is working.
The outputvoltage from the photosensor is approx 2,5V so it should be ok?
Regards
