4.0 Software Installation and 
Operation

 

4.1 Installation 

The CD provided in the LM32/LM40/LM41 Evaluation 
Board Kit contains the SensorEval software used to 
make the LM32, LM40, LM41 Evaluation Board operate 
with the user’s PC. It is assumed that the user will be 
using a PC with a Pentium

®

 III or higher processor and 

Microsoft Windows

®

 XP/2000/98/ME operating system.  

 
 The software is installed as follows: 
 

1.  Insert the LM32/LM40/LM41 Evaluation Board 

CD into the CD drive of the PC. See details in 
the readme.txt file. 

2. 

The software manual, provided on the CD, may 
be useful to the user during this process. 

3.  Follow all of the Installation instructions in the 

windows as the SensorEval software is 
installing. 

4.  The installation process will put an icon on the 

PC desktop so that the SensorEval program will 
run when the icon is double-clicked.  

 

4.2 Operation 

 

Follow the following procedure for operation the 
LM32/LM40/LM41 Evaluation Board using the 
SensorEval software: 
 

1.  Run the SensorEval program by either double-

clicking on the icon on the desktop or by 
selecting Start, Run, and browse to find the 
SensorEval.exe file. 

2.  Plug in the USB cable on both the PC and the 

LM32/LM40/LM41 Evaluation Board.  

 
Follow the register setup steps given in 2.0 Quick Start 
section of this User’s Guide. Make sure that you are 
following the given procedure for the specific evaluation 
board you are working with. 
 
Temperature and voltage monitoring can easily be done 
using external thermal diodes and/or external voltages 
applied to the pins that are jumpered on J2 and J3.  
Refer to the schematic, layout and electrical connection 
tables to be sure about the connections the user will 
make.
