how to use second ni6534 to make 64 bit parallel digital I/O possible

[Jaap]

I have installed 2 NI6534 cards to be able to write 64 bit data. I have connected the two NI cards using the flat cable connections. But how do I make the cards write 64 bit data ? Can you please give a small example.

Hi Jaap,

The trick is to use the RTSI Connect VI. This, combined with a RTSI cable, allows you to share the clock between the two boards effectively making them appear as a single 64 bit device. Here is an example program.
