Caution
The C terminals are internally connected to each other, but are not
connected to chassis ground. This isolation is intended to prevent ground loops and
does not meet UL ratings for safety isolation. You can connect the C terminals to
chassis ground externally. Refer to the specifications on
information about the power supply input range and maximum voltage from
terminal to chassis ground.
If you apply power to both the V1 and V2 inputs, the cRIO-9032 operates from the V1 input.
If the input voltage to V1 is insufficient, the cRIO-9032 operates from the V2 input.
The cRIO-9032 has reverse-voltage protection.
The following NI power supplies and accessories are available for the cRIO-9032.

RS-232 Serial Port
The cRIO-9032 has an RS-232 serial port that is implemented with an RJ-50, 10-position
modular jack 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. Refer to the
LabVIEW Help
for information
about the Serial VIs.
