I am having a problem with our AT-MIO-64E board on a PC with Windows NT 4.0
and NI-DAQ 4.9 and custom program written VC++. The program is installed
in two systems and runs fine. Am modifying the software and attempting to
test the modifications. After using SCAN_Setup and SCAN_Start to setup and
start acquisition with status code zero returned from these functions to
indicate no problems, DAQ_Check is used to look for the data. DAQ_Check continually
returns a status code of zero to indicate no problems but "retrieved" parameter
which is suppose to contain the number of bytes acquired is always zero.
Has anyone encountered this? Is this an indication that there is a problem
with the A/D converters on the board? Any ideas? TIA
