Property of DAQmx Channel

Specifies the data transfer mode for the channel.

DMA (10054) Direct Memory Access. Data transfers take place independently from the application.
Interrupts (10204) Data transfers take place independently from the application. Using interrupts increases CPU usage because the CPU must service interrupt requests. Typically, you should use interrupts if the device is out of DMA channels.
Programmed I/O (10264) Data transfers take place when you call DAQmx Read or DAQmx Write.
USB Bulk (12590) Data transfers take place independently from the application using a USB bulk pipe.
