Single Buffered input with 6533 card

I'm an RF test engineer who has been thrust into a DSP project.
I'm working with a 6533 board to do some simple digital data acquistion.
I want to single buffer my input for 4K of serial data set up as an 8-bit
group. In other words, I have 8 lines connected connect to DIOA0-7
and I'm interested in 4K of serial data over each of thos lines. I keep
getting an error when I run my program. The error occurs at the
"DIG_Block_In" function. I want to acquire 38000 points. The run-time
error that tells me to set the array buffer to some ridiculously large
amount
(4 billion bytes?). Any thoughts on where I might be going wrong or
on how one would setup a buffer to acquire data in the manner that
I wish?
