UART communication fails between NI myRIO and XBEE PRO S3B

I am trying to connect an XBee Pro S3B to an NI myRIO, via a UART visa connection. I have all of the serial settings the same, such as Baud rate, parity, stop bits, and data bits. But every time I try to sent anything to the XBee or read from the XBee i get an error that the serial communication was unsuccessful.

Are you able to communicate between the two xbee modules when mounted on interface boards and your PC?
