Figure 2-1. A Typical Configuration for the DAQCard-1200

Configuration

The DAQCard-1200 is completely software configurable; refer to your

software manuals to install and configure your software.

If you are using NI-DAQ, refer to your NI-DAQ user manual or function

reference manual. The software installation and configuration instructions

are in Chapter 1. Find the installation and system configuration section for

your operating system and follow the instructions given there.

If you are using LabVIEW, you do not need the NI-DAQ manuals; the

software installation instructions are in your LabVIEW release notes. After

you have installed LabVIEW, refer to the Data Acquisition, VXI, and GPIB

Installation Notes section of Chapter 1, Required Configuration,

Installation, and Upgrade Information of your LabVIEW Version 5.1
