cRIO-9012/9014 Operating Instructions and Specifications
Powering On the Controller
Plug in each power supply to the CompactRIO system. The controller runs
a power-on self test (POST). During the POST, the Power and Status LEDs
turn on. The Status LED turns off, indicating that the POST is complete. If
the LEDs do not behave in this way when the controller powers on, refer to
the
Understanding LED Indications
section.
You can configure the controller to launch an embedded stand-alone
application each time you boot the controller. Refer to the
LabVIEW Help
for more information.
Connecting Serial Devices to the Controller
The controller has an RS-232 serial port to which you can connect devices
such as displays or input devices. Use the Serial VIs to read from and write
to the serial port. For more information about the Serial VIs, refer to the
LabVIEW Help
.
