Hi Mondeep, For the 4472, there is a 32->24 bit lossless mode and a 32->16 bit lossy mode. On 16 bit MIO, there is a 16 bit no compression mode and an 8 bit lossy mode. For 12 bit MIO, there is a 16->12 but lossless mode and and an 8 bit lossy mode.
Unfortunately, we do not support the HSDL VIs that I had talked previously about, and so I am unable to post them here. I apologize for this inconvenience. Hope this answers all of your questions! Let me know if you need anything else! Jeremy L. National Instruments
