Last 2 scans of packet can be read when I received the following packet.

[Germain H.]

I'm using a 6533 with Labview and settings like this: pattern, external clock, 16-bit group (port 0-1) and continuous mode.

This card receives high-speed packets.

My problem is the last two scans can't be read until the next packet arrived. Is it normal?

Is it a Labview issue?
Is there any workaround?

Germain;

One thing you can try is to reduce the rate of your application and see if that solves the problem. I'm saying that because since that board of yours doesn't have a big on board memory, it relies at the DMA data transfer very often, becoming system dependent. Try that out, and if that is the problem you will need either to reduce the rate of the task or work with the 6534 board which has a 32Mbytes on board memory.
Hope this helps.
