The USB 3.1 Type-C Dual Role port implements dual role functionality and is capable of functioning as either a USB 3.1 Gen1 host or device. When operating as a host, the port supports common USB devices such as mass-storage devices, keyboards, mice, and USB cameras. When operating a device, use this port to connect the cRIO-904x to a host PC. The USB device functionality provides an alternate method to connect the cRIO-904x to a host PC and is intended for configuration, application deployment, debugging, and maintenance. The role of the port is determined automatically based on the cable inserted into the port. For example, the port will automatically function as a device when the cRIO-904x is connected to a host PC using the NI USB Type-C male to Type-A male cable provided in the kit.
The USB 3.1 Type-C with DisplayPort Alt Mode port implements both a USB 3.1 Gen1 host and a DisplayPort 1.2 source using the USB Type-C DisplayPort alternate mode. Use a USB Type-C video adapter or monitor supporting the DisplayPort alternate mode to use this port as a display output. Alternatively, this port may be used as a standard USB host port and supports common USB devices such as mass-storage devices, keyboards, mice, and USB cameras. Use a USB Type-C male to USB Type-A female adapter to use this port with USB devices implementing a type-A male connector. Use a USB Type-C multiport adapter to simultaneously use this port as a display output and a USB host port.

The Programmable Function Interface (PFI) terminal is a SMB connector.
Programmable Function Interface—You can configure the PFI terminal as a timing input or timing output signal for AI, AO, DI, DO, or counter/timer functions.
The cRIO-904x has a power connector to which you can connect a primary and secondary power supply. The following table shows the pinout for the power connector.
|V1||Primary power input|
|V2||Secondary power input|
The C terminals are internally connected to each other, but are functionally isolated from chassis ground. This isolation is intended to prevent ground loops, but does not meet IEC 61010-1 for safety isolation. You can connect the C terminals to chassis ground externally. Refer to the specifications on ni.com/manuals for 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-904x operates from the V1 input. If the input voltage to V1 is insufficient, the cRIO-904x operates from the V2 input.
The cRIO-904x has reverse-voltage protection.
