Yes it is a ttl signal when i wire it to osscilloscope i see a constant line on 5v.I wired it correctly because i got wiring information from authorized person of sensor.my daq is ni usb 6229 bnc.Shortly according to the sensor output signal should be square wave

Actually it is not exactly 5V fluctuating a bit but very small.I am providing the sensor and how i wired it., xample of labview i used count digital events pause trig but i have seen no data.

They sent me this picture. i wired signal cable to pfi4. supply voltage is 12V.resistance is 2.2k because sensor manufacturer said you have wire a pull up resistor as in the picture.
