Hi. I am using cRIO-9039 with NI-9871 Serial Interface. cRIO has max baudrate of 115200 but 9871 supports baudrates of upto 3686400 so I think it should work and I am making some mistake. My approach is as following:
1) I am using LabView 2014 SP1 with August 2015 Drivers
2) I am using NI Visa 15.0 Interface 3) I am working in Scan Mode
4) I am unable to change baudrates of 9871 ports even from NI-Max
5) Whether in LabView or NI-Max, if I set baudrate greater than 115200, I guess error message that it is unsupported.
