Can't change serial port settings on cRIO 9072 controller.

I am attempting to connect a device to the RS-232 serial port on a cRIO 9072 controller.  MAX sees the port just fine, and it is apparently working properly, but does not allow me to change the port settings.  The device I am attempting to connect operates at a different baud rate than the (apparent) default for the cRIO port.  Help would be greatly appreciated.

Hi Obxetec,

I believe you have to configure the port in software when you establish the connection. The VISA config serial port VI has a baud rate input that will configure the port. You should call this VI prior to calling the read and write VIs.

Let me know if this helped.
