NI 9871 460.8 kbaud works but not 921.6 kbaud

NI 9871 460.8 kbaud works but not 921.6 kbaud

‎07-22-2015 03:06 PM

Hi,

 

I have a PCIe-based RS422 card that can write to our NI 9871 cRIO module at 460.8 kbaud but the data is garbled at 921.6 kbaud (which is supposed to be supported ion the 9871).

 

A loopback test on the PCIe card shows the 921.6 kbaud data is fine.

 

Attached is my test program.

 

I've tried playing with Project settings but I don't see a difference.

 

Steve
