Quick Start

Required Equipment

Before you begin, the following equipment is needed:

• Computer running Windows 95, 98, or 2000 (Note:

Windows 2000 requires the installation of a driver;

refer to Win2000.pdf or Win2000.txt located on the

diskette.)

• Parallel printer port (this is a 25-pin socket on the

back of the computer)

• Standard 25-pin, straight-through, male-to-female

cable (printer extension cable) to connect the com-

puter’s parallel port to the Maxim SMBus interface

board

• DC power supply capable of supplying any voltage

between 7V and 20V at 100mA

• 500mA DC power supply rated at 5V or 12V,

depending on the fan

• DC power supply capable of supplying 5V at 50mA

• 5V or 12V fan rated up to 250mA with a tachometer

output

Procedure

1) Carefully connect the boards by aligning the 20-pin

connector of the MAX6660 EV kit with the 20-pin

header of the MAXSMBUS interface board. Gently

press them together.

2) Make sure switch S1 on the MAX6660 EV kit is in

the OFF position.

3) Make sure JU3 is set to the 1-2 position.

4) Connect a fan to either J2 or the pads FAN+, FAN-,

and TACH.

5) Connect a cable from the computer’s parallel port

to the SMBus interface board. Use a straight-

through 25-pin female-to-male cable. To avoid

damaging the EV kit or your computer, do not use a

25-pin SCSI port or any other connector that is

physically similar to the 25-pin parallel printer port.

6) The MAX6660.EXE software program can be run

from the floppy or hard drive. Use the Windows pro-

gram manager to run the program. If desired, you

may use the INSTALL.EXE program to copy the files

and create icons for them in the Windows 95/98/2000

Start menu. An uninstall program is included with the

software. Click on the UNINSTALL icon to remove

the EV kit software from the hard drive.

Do not turn on the power until all connections

are made.

7) Connect the fan power supply to the VFAN and

PGND pads.

8) Connect the 7V to 20V power supply to the pads

labeled POS9 and GND1 of the SMBus interface

board.

9) Connect the 5V power supply to the VCC and

AGND pads.

10) Turn on the power supplies.

11) Turn on the EV kit by moving S1 to the ON position.

12) Start the MAX6660 program by opening its icon in

the Start menu.

13) Observe as the program automatically detects the

address of the MAX6660 and starts the main program.

Note: The MAX6660 reads the address select pins at

device power-up only.

Detailed Description

User-Interface Panel

The user interface is easy to operate; use the mouse, or

press the Tab key to navigate with the arrow keys. Each

of the buttons corresponds to bits in the command and

configuration bytes. By clicking on them, the correct

SMBus write operation is generated to update the inter-

nal registers.
