How do I configure the NI-6534 to send a pattern generation of a buffer of 16 bit words and receive the same number of words (as if talking to a FIFO or looping the output back to the input) at 10 MHz on the internal clock? In other words, for each word I send I need to receive a word. I am currently using single buffering, ports C & D for output, A & B for input, no external gating, latched input, unlatched output, timebase of -3, and interval 2. I call DIG_Block_In and then DIG_Block_Out with the data. All I get back is zeroes. I think this is a configuration problem. I am using LabWindows/cvi. Please help.
