1) What is the VISA resource?
2) What is a XBEE connection and where is the serial port that I can connect the Arduino to the cRio?

We're trying to do the same thing and running into the same problem of not knowing what VISA Resource Name to use. I assume we need to know the name that indicates the RS232 port on the cRIO.
XBEE makes a series of little radios that you can communicate over as if they are RS232 Serial ports. They are commonly used in small robots to provide a link back to a controlling computer or in a mesh network.
While there are other good ways to communicate between the cRIO and the Arduino, including I2C and GPIO lines, I'd prefer to use RS232 because we're actually controlling a 32x32 array of LEDs and would like to let the cRIO send us strings to display on the array.
So, please, if anyone out there knows how to make this work, please post a reply. If I figure it out, I'll post a reply here, myself.
