Figure 18. Installing a Ferrite on Two USB Cables

Refer to Figure 1 for the location of the two USB host ports on the cRIO controller. Refer to

Table 2 for USB host port pin locations and signal descriptions.

Caution Do not hot-swap USB devices while the cRIO controller is in a hazardous

location or connected to high voltages. If the cRIO controller is not in a hazardous

location, you can connect and disconnect USB devices without affecting operation.

USB Device Port

The USB device port, shown in Figure 1, is intended for use in device configuration, application

deployment, debug, and maintenance. For example, you can install software or driver updates

through the USB device port during field maintenance instead of interrupting communication on

the RJ-45 Ethernet ports.

Caution National Instruments requires a locking USB cable, such as part number

157788-01, in order to meet the shock and vibration specifications of this product.
