Measurement Computing USB-DIO96H driver issue with Labview 2012 SP1 on Windows 7 x64

[SunshineDesign]

Is anyone else having issues with measuremetn Computing's USB-DIO96H driver in Labview 2012 SP1. It throws warnings in Labview when loaded that are unresolvable as you can't save to the DLL driver file. Also it regularily crashes Labview randomly. I am not impressed with their driver. Anyone have any suggestion other than replacing with NI-DAQ solution, which I am working on?

Where did you get the drivers you are referring to? Did you download them from the manufacturer's website?

[SunshineDesign]

Yes and the latest update from them as well.

I've taken a look and I don't see any drivers available for that device on ni.com. There are two potential workarounds that would both involve building your own driver:

1. Write a LabVIEW application that calls functions on the DLL you downloaded from Measurements Group

2. Write a LabVIEW application that addresses the device using NI-VISA and serial communication.

Some resources if you choose to go down that path:

Hope this helps!

Of course there is nothing from NI. It is a DAQ device from Measurement Computing. Their driver does have LabVIEW functions that call the DLL. Using VISA and serial makes little sense. It would be like trying to use those functions instead of DAQmx and an NI DAQ device.

SunshineDesign,

I'm not sure why you posted here. You have not mentioned the exact errors you are getting and that is pretty essential information. I have not used that exact card but have used other mc devices. Have you checked with their technical support? You need to specify the version of LabVIEW, your os, and the version of the mc driver as well as the errors when you do contact them.

Dennis I did post what my Labview, OS and the Meas Computing Driver (latest download available from Meas Computing). I did not post a specific error as I got none to give, just a Labivew crash with little info to go on. The Meas Comp support engineer seems to be indicating that the driver may be crashing if hardware is not connected and Meas Computing Driver, as DLL can't resolve the handle of the card at design time when it checks that the board(s) is configured by InstaCalc, which it cannot do if the device is not connected. If this is the case, this is not good as you MUST have the card connected to do ANY development with it. NI DAQmx does not require this. I will be watching to see if this is the case. If the crashing does not stop, I will have to replace with NI DAQmx so I have a more stable test system.

I am also checking to see if Labview x64 is causing the issue and have ported the project over to x32 Labview 2012 SP1 to see if there is any difference.

[BauerPower]

Have you already chosen a DAQ device for your application? PM me if you would like some assistance picking one out.

Thanks for the offer Rob. I think I can select one OK. I've been around for a while with NI stuff. I also think I may have resolved the issue by going to Labview x32 instead of x64. I have not had Labview crash for 2 days now and am still keeping an eye on it.
