Logging to external USB device from cDAQ 9139

Hello,

 

I am using a cDAQ 9139 running the RTOS and developing with a combination of LabView 2013, Real Time Module, and daqmx that I'd like to configure for external USB device logging tasks.  It doesn't appear to me that any of the USB drives I've connected are being auto detected.  Can someone point me to an article on setting up USB drive logging or maybe point out some things I might be doing wrong.  Maybe I'm not looking in the right places to find the drive.  Any help would be greatly appreciated.

 

Thanks.

Hi Michael-

 

This KB entry explains that a USB mass storage device added to a LabVIEW Real-Time ETS-based system can be accessed as drive U:\ using the LabVIEW File I/O functions.  This is true for cDAQ-9138 and cDAQ-9139 systems.

 

Hopefully this helps-

Make sure that you formatted it with the FAT32 filesystem, Pharlap cannot use NTFS or exFAT etc.

 

Additionally if you have a monitor attached to the system you may see a console message when the usb device is connected.

 

There may also be some settings in the controllers BIOS settings that pertain to USB that you could check.

Formatting the USB drive in FAT32 file system solved the issue.

 

I can now see the device register when connected and am recording to it.

 

Thanks for all the help and the quick replies.
