Need recommendation on a I/O Card

[Damian G]

I need to send/receive serial data (2048bits) at 250 k/s with no protocal, can someone recommend and I/O card and VI's that can do this. Thanks for any info.

Also any VI's out there that can generate a CRC-16

Hi Damian,

The PCI-6533 (or PXI-6533) high-speed digital I/O card would be perfect for this type of application. It can achieve rates in the MHz range for finite transfers. It is 32 bits wide (I assume you only need 16). It is also a clocked protocol. Here is the link to the product page:

As for a VI that does CRC-16, LabVIEW doesn't have this algorithm built in but I've seen other developer exchanges that mentioned the protocol. Here are the links:

Anyway, hope that helps. Have a good day.

thanks for the info Ron. I have a PCI-6534 that I
was planning on using. Just making sure that there
was not something out there that would be a better fit.
