The 6024E does not have DMA capabilities. So basically you cannot read and write at the same time. I think that you are going to have to read one channel then right to the other to get this to work. Depending on how fast you need this sequence to go it should work. If you need very precise timing then you will need to get a card that has DMA capabilities.
