Installing the Hardware

Connecting the USB Cable

USB modules can be connected directly to the host PC, to a powered USB hub, or to an NI

PXI or PXI Express chassis featuring a USB port.

1. Connect the USB cable to the NI USB-7855R using the cable device port.

2. Connect the other end of the USB cable to the host PC, powered hub, or chassis.

3. Use the jackscrew on the locking USB cable to securely attach the cable to the

NI USB-7855R.

Powering the Module

Caution To ensure the specified EMC performance, install the included snap-on

ferrite bead onto the DC power cord of the power supply in accordance with the

instructions provided.

1. Install the ferrite bead by opening the housing and looping the power supply once through

the center of the bead. Ensure the ferrite bead is as close to the end of the cable as

practical.

2. Close the ferrite bead until the locking tabs engage securely.
