Hi s-p,
How do you have the timing configured for this task? What is the sample rate? Your incoming clock may be running too fast to acquire any data points.

Hi Luke
by counting input and then frequency DAQmx there is no way to set the sampling rate and timing stuff .i just configured to get continuous sample.what is incoming clock?
i have been working in this problem for 4 days.please give me some advises how to fix that.

Hello s-p,
I was just checking the spec sheet of you device. How's the output selection setup? Inverted or non-inverted? Have you tried using Express vi's instead of lower level? Give it a shot, for the mean time I will double check my old vi's related to this though I've used IRS-P type sensor on my project.

Thank you
i found the problem.it was the clip cable i was using.

I have a Monarch ROS that I'm tring to use with a USB-6210. It's not clear to me what pin to plug the black wire (http://www.monarchinstrument.com/pdfs/manuals/1071-4854-118R.pdf) to on the 6210.
1. Do I need to power the ROS with the 6210
2. I'm using signal express and can not seem to get a clean signal. jumps all over. I don't think I am connected to the correct pin. Currently on Pin1. Also tried grounding to pin 5 with no luck.
3. My goal is to detect RPM on a computer power supply fan. I have a green light on my ROS when the fan is active.

4U2C,
You have resurrected a posting that is 4 years old.
There is a voltage supply line on the USB-6210 on pin 10 that may be used to power the sensor if not already powered from another source. Looking at the information on the sensor, it does need to be powered. Here's the spec on the supply pulled from the manual
http://www.ni.com/pdf/manuals/371932f.pdf
Power Limits
+5 V terminal as output2
Voltage ....................................... 4.6 to 5.2 V
Current (internally limited) ........ 50 mA max, shared
You may want to review the connections and how the counters work on the 6210 in the user manual. If you don't have it, it is linked here.

I resolved the issue after posting this. My ground was not sourced from the 6210. When I did this (and used it's 5v) it worked great. I returned today after letting it run over night and mysteriously my RPM's doubled... I think I have a flakey 6210.
Thanks for the reply on this old thread. Still valid even today 😉
