All of the NI drivers can be located on the
NI Drivers and Updates page. In order to find the required driver, you will need to know what the device is called. You can find this information in several different ways. One way is to visually inspect the device. If it is an NI device then it should list the device name somewhere on the board. Also, you could locate the part number. This number usually ends in -01 or -02 and is printed near a bar code. If you can find this number, then simply type it into the search on ni.com to locate the name of the device.
When the name of the device is figured out, you should then determine the appropriate driver for the device from the Drivers and Update page linked above.
If it is not an NI device, then you will want to view the device manufacturer's webpage for available drivers.
Please do not post back to this message as I do not believe the message pertains to the NI Measure software. The question is more related to a specific piece of hardware. Thus, you should repost this question, if another exists, to the appropriate NI Hardware category.
Best of luck.
