Introduction

This manual contains detailed instructions for installing and configuring
the National Instruments PCI-7041. The PCI-7041 is a multifunction I/O
board with an embedded processor. Use LabVIEW RT and NI-DAQ to
create embedded, real-time applications that run on the PCI-7041.

Overview

The PCI-7041/6040 RT Series board is a plug-in PCI board with an
embedded processor and measurement functionality. The PCI-7041,
LabVIEW Real-Time (RT), and measurement software, such as NI-DAQ,
provide an easy-to-use system for real-time applications.

Three subcomponents make up the PCI-7041: the processor board, the
I/O daughterboard, and the accessory board, as shown in Figure 1-1.
The following section explains each subcomponent in further detail.
