NI6211 USB Data Streams

[david.ball]

Hello,

In have just purchased a NI6211 M series USB device that has USB data streaming, but I can not figure out how to set the task up. I have found the property node for data transfer mechanism but I am getting the error message :

Possible reason(s):

Buffered operations cannot use a Data Transfer Mechanism of Programmed I/O for this device and Channel Type.

Non-buffered operations cannot use a Data Transfer Mechanism of Interrupts or DMA for this device and Channel Type.

Property: CI.DataXferMech
Corresponding Value: USB Bulk

Property: SampTimingType
Corresponding Value: On Demand

Channel Name: BulkCTR

Task Name: _unnamedTask<3>

Could you give me some pointers as to where to start with setting up this device as I have spent hours searching with no luck so far.

Hi David,

why do you want to fiddle with "DataXferMech" at all?

DAQmx will handle the data transfer from USB6211 to your LabVIEW VI on its own…
