Hello community.I need to build VI that will collect torque data using a Mark-10 torque sensor. It connects to a PC via usb and collects data with a canned sw solution that is buggy. I would like to know how to do this better with Labview. What equipment would I need to interface/connect this sensor to a PC. See the address below for detailed desciptions of sensor and indicator. I'm not very experienced with Labview and any help would be appreciated. I have at my disposal NI 9236 and 9237 modules to work with. Is there any other recommended HW?

What in their documentation makes you think that you using LabVIEW or NI-9236 or NI-9237 would be in the least bit compatible?
They have compatible software. Just use it.

Using the supplied VI/executable has been problematic. When the VI runs for a few hours it starts to miss data points and if there are any fluctuations in power to the lab it will crash. This VI is written in such a manner that after each scan it doesn't write to the data file....only after the alloted time the VI was set up to run. I mentioned the modules to just let the community know what I had at my disposal.

Can you provide a screenshot of the code you are using?

There are 2 ways to do this. 1) Pull the analog signal off of the individual pins on the back and read the DC voltage with a NI DAQ. you'll need to do a calibration to convert the voltage signal into usable data. 2) you can pull the calibrated data out just by using VISA and a USB com port, no extra DAQ hardware needed. I've it for a number of Mark-10 devices. Parsing the serial stream is tricky (i'm only a casual user these days, and not very good at serial data nuances, however) - I've had issues with dropping data points because the parsing loses track if you change modes or something, but otherwise it's a stable read. you can set up the save however you like.
Their canned software IS definitely made in Labview (and buggy).
