How can I increase the retriggering speed of 6534?

Question

I try to write into PCI 6534 buffer and generate the same output every time a trigger pulse is detected at the "start trigger" pin.
I'm playing with retriggabble_output.vi example using 1 Mhz clock speed. The problem is that there is about 4msec dead time between two triggering events.
How can I reduce this time? ( the program doesn't work without the "digital I/O wait" VI. So I set it to 1 msec).
My second question is:
How can I write a long data sequence onto the buffer and output one portion of the data every time a triggering event occurs? For instance, the data in the buffer is a 128 element array, and the output is only 32 elements upon a reception of a triggering signal.When the next triggering sign
al is received the following 32 elements in the buffer are sent to the output port.
Thank you,

Hello,
When trying to retrigger output with a 653x device, there is some amount of software overhead. This is unavoidable as the board itself does not support retriggering. However, there are two solutions to this problem, one is a fast software reset, and the other is to create a retriggered pulse train.
If you want to use software for resetting the trigger, then there is a good example for doing this. The example uses a call that preserves a configuration setup. Take a look Here.
If you would like to use hardware to solve this problem, take a look pd4?p_guid=B123AE0CBAFD111EE034080020E74861&p_node=DZ52321&p_source=External�>Here. This example does require a counter timer board, which supports retriggering.
