Introduction

This chapter lists what you need to get started and includes a brief
description of the USB-8486 hardware and the NI-FBUS software.

What You Need to Get Started

To install your NI-FBUS software, you need the following items:

❑

USB-8486 hardware

❑

Installation CD kit

❑

Windows installed on your computer

Hardware Description

The USB-8486 is a USB high-power bus-powered device that is
compatible with both USB 2.0 High-Speed and Full-Speed ports. The
USB-8486 is a F

OUNDATION

transfer rate of 31.25 kb/s.

Software Description

Your kit includes either the NI-FBUS Communications Manager software
or the NI-FBUS Configurator software. Depending on the system you
purchase, you may receive both disks. If this is the case, use the NI-FBUS
Configurator software.

The NI-FBUS Communications Manager software is used by the interface
boards to communicate over the bus. Additionally, it provides a high-level
API advanced users can use to interface with the National Instruments
