USB Device Port
The cRIO-9031 USB device port is intended for device configuration, application deployment,
debugging, and maintenance. For example, you can use the USB device port to install software
or driver updates during field maintenance instead of interrupting communication on the RJ-45
Ethernet ports.
Caution
Do not hot-swap USB devices while the cRIO-9031 is in a hazardous
location or connected to high voltages. If the cRIO-9031 is not in a hazardous
location, you can connect and disconnect USB devices without affecting operation.
The following table shows the pinout for the USB device port.
