3. SOFTWARE

The evaluation software was developed with Lab

Windows/CVI™, a software development package

from National Instruments. The software is de-

signed to run under Windows 95™ or later, and re-

quires about 3 MB of hard drive space (2 MB for

the CVI Run-Time Engine™, and 1 MB for the eval-

uation software). Before installing the software,

read the readme.txt file for any last minute updates

or changes. More sophisticated analysis software

can be developed by purchasing the development

package from National Instruments (512-794-

0100).

3.1 Installing the Software

Installation Procedure:

1) Turn on the PC, running Windows 95™ or later.

2) Insert the Installation CD into the PC.

3) Run the appropriate installer package (either

instmsi.exe or instmsiw.exe, depending on the

operating system). See the readme.txt file for

more information.

4) Run EVL5451A.msi to begin installation.

5) During installation the user will be prompted to

enter the directory in which to install the Lab-

Windows CVI Run-Time Engine™. The Run-

Time Engine™ manages executables created

with Lab Windows/CVI™. If the default directory

is acceptable, select OK and the Run-Time En-

gine™ will be installed there.

6) After the Run-Time Engine™ is installed, the

user is prompted to enter the directory in which

to install the CDB5451A software. Select OK to

accept the default directory.

7) Once the program is installed, it can be run by

double clicking on the EVL5451A icon, or

through the Start menu.

Note:

The software is written to run with 640 x 480

resolution; however, it will work with 1024 x 768

resolution. If the user interface seems to be a

little small, the user might consider setting the

display settings to 640 x 480. (640x480 was

chosen to accommodate a variety

of computers).

3.2 Running the Software

3.2.1 Getting Started

The CDB5451A Evaluation software allows the

user to obtain, display, and save data that is ac-

quired by the CS5451A chip. Before running the

software, the first step is to make sure that all of the

headers that are listed in Table 2 are set to an ap-

propriate setting, the exact setting should be deter-

mined by the user. Next, with the user’s DC power

supplies still turned off, the user should connect

the necessary power leads to the banana jack

power connectors on the evaluation board. Refer

to Table 1 for various acceptable power supply

connection configurations. Then at this time the

user should turn on their DC power supplies, which

should apply power to the CDB5451A. Several

test point locations are available on the evaluation

board. The user can check these test points with a

voltmeter, to make sure that the voltages at these

test points are at the expected levels. When the

user has verified that the power supply levels are

constant, the user should connect the included 25-

pin cable between J17 of the evaluation board and

the parallel port on the user’s PC. The user should

then press down on the S1 “RESET” switch, and

make sure to hold it down for at least ~0.5 seconds

before releasing. Finally, the user can start the PC

software. To start the software, double click on the

EVAL5451A icon, or initiate through the Start

menu.
