Preface

The

DDA-08/16 User’s Guide

provides the information needed to set up,

install, and use DDA-08 and DDA-16 boards.

The manual is intended for data acquisition system designers, engineers,
technicians, scientists, and other users responsible for setting up, cabling,
and wiring signals to DDA-08 and DDA-16 boards. It is assumed that
users are familiar with data acquisition principles and with their particular
application.

The

DDA-08/16 User’s Guide

is organized as follows:

●

Section 1 provides an overview of the features of DDA-08 and
DDA-16 boards, including a description of supporting software and
accessories.

●

Section 2 provides a detailed description of the features of DDA-08
and DDA-16 boards.

●

Section 3 describes how to unpack, configure, and install DDA-08
and DDA-16 boards.

●

Section 4 describes how to attach accessory boards and how to wire
signals to DDA-08 and DDA-16 boards.

●

Section 5 describes how to use the Control Panel to test the functions
of DDA-08 and DDA-16 boards under Windows



.

●

Section 6 describes how to calibrate and test the functions of DDA-08
and DDA-16 boards under DOS.

●

Section 7 provides troubleshooting information.
