Page 110 General purpose digital sensors typically have three wires: power (typically +5V), ground, and signal. The preferred method for wiring a digital sensor to the NI 9760 is to wire the sensor power wire to one of the 5V OUT pins (pins 1-3, 20-22), the sensor ground wire to one of the sensor ground pins (pins 10-13, 29-31), and the sensor signal wire the IN+ pin corresponding to the desired channel (pins 4-9).
