Chapter 2 Installation and Configuration

© National Instruments Corporation 2-3 DAQCard-700 User Manual

If you are using LabWindows/CVI, the software installation instructions are in Part 1,

Introduction to LabWindows/CVI, of the Getting Started with LabWindows/CVI manual. After

you have installed LabWindows/CVI, refer to Chapter 1, Configuring LabWindows/CVI, of the

LabWindows/CVI User Manual for software configuration instructions.

Analog I/O Configuration

At startup, the DAQCard-700 defaults to the following configuration:

• Referenced single-ended input mode

•±10 V analog input range

Table 2-1 lists the available analog I/O configurations for the DAQCard-700 and shows the

default settings.

Table 2-1. Analog I/O Settings

Parameter Configuration

Analog Input Polarity Bipolar—±10 V (default setting)

Bipolar—±5 V

Bipolar—±2.5 V

Analog Input Mode Referenced single-ended (RSE) (default setting)

Differential (DIFF)

The analog input circuitry is software configurable.

Warning: Connections, including power signals to ground and vice versa, that exceed any

of the maximum signal ratings on the DAQCard-700 can result in damage to the

DAQCard-700 card. National Instruments is NOT liable for any damages or

injuries resulting from incorrect signal connections.

Analog Input Mode

The DAQCard-700 has two different input modes–referenced single-ended (RSE) input and

differential (DIFF) input. The single-ended input configuration provides 16 channels. The DIFF

input configuration provides eight channels. Table 2-2 describes these configurations.
