PCI-QUAD04 User's Guide Installing the PCI-QUAD04

Installing the software

Refer to the Quick Start Guide for instructions on installing the software on the Measurement Computing Data

Acquisition Software CD. This booklet is available in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-

Quick-Start.pdf.

Configuring the PCI-QUAD04

Before installing the board, configure the channel input mode for either single-ended or differential. You set the

channel configuration with a set of jumper blocks on the board. Each jumper is labeled for its functionality. By

default, the board is shipped with the channels configured for single-ended operation, with no termination

resistors installed.

Channel input mode

To configure for single-ended operation, place a jumper between pin 2 and pin 3 (labeled SE). To configure for

differential operation, place a jumper between pin 1 (labeled

DIFF) and pin 2. A single-ended configuration is

shown in Figure 3.

Input mode jumper settings are listed in the table below.

Termination resistors

Although termination resistors typically are not required, SMT pads on the PCI-QUAD04 are open and labeled

to allow you to install terminating resistors from the various inputs to ground.
