General Description
The LM87 Design Kit allows quick connection and evaluation of the LM87 System Hardware Monitor
integrated circuit. The Evaluation Board connects to and derives its power from the parallel printer port of a
PC. The software was written using Visual Basic 5.0 and is compatible with PC type computers running
Microsoft Windows 95 or Windows 98 operating system. Minimum 800 by 600 graphics resolution is
recommended for best viewing.
With the LM87 evaluation board and software you can:
•
Configure the LM87 registers
•
View the LM87 register contents
•
Quickly gain familiarity with the LM87 features and operation
1.0 Setup
1.1 Installation
The LM87 Design Kit consists of the LM87 Evaluation Board, software on three 3.5” diskettes, and this
instruction manual.
•
Insert Disk 1 into the 3.5” floppy drive of the PC. Install the software by clicking on the “Start” button,
selecting “Run” and typing in the name of the drive followed by “\setup”. For example type a:\setup.
Then click on “OK” or press the Enter key. Alternatively, you can use the Windows Explorer to view
the drive where the diskette is inserted, and double click on the “setup.exe” file.
•
Follow the on screen instructions and select the drive and folder you would like the software installed
on. The LM87 evaluation software uses approximately 3 Megabytes of disk space.
•
Some features of the program require that Adobe Acrobat Reader be installed on the system. If this
software is not present, primary software functions are available, but you will not be able to access the
LM87 datasheet, evaluation board schematic, and user manual files. The Adobe Acrobat Reader
software is available at:

Board Preparation and Connection
•
Make sure the jumpers are placed on the evaluation board at JP1, JP5, JP6-+5V, JP6-FAN/AIN1, JP6-
FAN/AIN2, JP6-CI, JP7-INT# are installed.
•
Run the software by clicking on the Windows “Start” button, then selecting “Programs->LM87 -
>LM87Eval” to launch the program.
•
Select the parallel printer port address and the device address of the evaluation board (default 00 with
ADD_HI and ADD_LO not installed).
•
Connect the board to the parallel printer port of the PC directly or through a cable less than 6 feet (2
meters) long.
