32 bit operation in pattern i/o with pci6534

[Vishal]

I want to check the pattern i/o mode completely.I can check the 8 bit and 16 bit operations by looping.i.e. writing to a port,connecting that port to another input port and then reading the other port.This way i can check 8 & 16 bit operations.
But if i want to write a 32 bit data to the port and want to read the written value back.Is it possible using pattern i/o?
Is it possible that in a same vi, i configure the four port combination(0:3) as input and output simultaneously?

Hi Vishal,

In pattern I/O you can't read from the same port you are writing to. When you configure the group, you configure it for pattern input or output. The card is not capable of internally looping the output back into the card. Hope that helps.
