RS-232 Serial Ports

The cRIO-9068 has two RS-232 serial ports to which you can connect devices such as displays

or input devices. Use the Serial VIs to read from and write to the serial ports. Refer to the

LabVIEW Help for information about the Serial VIs.

Find examples on how to use NI-Serial or NI-VISA to perform serial communication in the

NI Example Finder. The NI Example Finder is located on the Help menu in the LabVIEW

Help.

Note The RS-232 serial ports cannot be accessed by the user application when the

Console Out startup option is enabled.

Note For information on serial port behavior during FPGA reconfiguration, visit

ni.com/info and enter Info Code crioserial.
